It is specified in the standards document RFC 6550 and is the emerging standard for routing in Wireless Sensor Networks. RPL has been widely criticized for a number of reasons, including underspecifi- cation and complexity of implementation. This thesis analyzes the RPL routing standard with regards to specification, performance, comparison with other routing standards, open source and industrial implementations, as well as improvement e↵orts. It also proposes an alternative to the RPL routing standard, RPL-Lite, that overcomes the shortcomings of the current RPL design. RPL-Lite reduces the feature set by including only the most necessary features required for routing. By doing so, it reduces the implementation complexity and makes it more suitable for deployment on resource constrained nodes. i Dedication I would like to dedicate this work to the Almighty, whose

Minden olyan részt, amelyet szó szerint, vagy azonos tartalomban, de átfogalmazva más forrásból átvettem, egyértelműen, a forrás megadásával megjelöltem. I, the undersigned Gergely Ács hereby declare that this Ph.D. dissertation was made by myself, and I only used the sources given at the end. Every part that was quoted word-for- word, or was taken over with the same content, I noted explicitly by giving the reference of the source. Budapest, 2009. április 8. ................................ Ács Gergely iii Abstract Routing is a fundamental networking function in every communication system, and multi- hop wireless networks are no exceptions. Attacking the routing service, an adversary can easily paralyse the operation of an entire network. Compared to traditional wired networks, such attacks can be performed relatively easily in wireless networks due to the unsupervised access to the wireless medium. The malicious manipulation of some routing messages results in the dissemination of incorrect routing information which can eventually lead to network malfunction. Even more, intermediate nodes can be corrupted, and thus, exhibit arbitrary behaviour. Considering these facts, securing routing protocols is a primary task, however, designing such secure routing protocols is not a straightforward procedure. A widely used method has been so far to identify different types of possible attacks against routing, and to define routing security implicitly as resistance to these attacks.

Received: 23 March 2019; Accepted: 5 May 2019; Published: 9 May 2019 Abstract: The emergence of the Internet of Things (IoT) and its applications has taken the attention of several researchers. In an effort to provide interoperability and IPv6 support for the IoT devices, the Internet Engineering Task Force (IETF) proposed the 6LoWPAN stack. However, the particularities and hardware limitations of networks associated with IoT devices lead to several challenges, mainly for routing protocols. On its stack proposal, IETF standardizes the RPL (IPv6 Routing Protocol for Low-Power and Lossy Networks) as the routing protocol for Low-power and Lossy Networks (LLNs). RPL is a tree-based proactive routing protocol that creates acyclic graphs among the nodes to allow data exchange.

  • A Secure Routing Algorithm
    TinyTermite: A Secure Routing Algorithm A Thesis Presented for the Master of Science Degree The University of Tennessee at Chattanooga Joshua L. Patterson December 2008 To the Graduate Council: I am submitting a thesis written by Joshua L. Patterson entitled “TinyTermite: A Secure Routing Algorithm”. I have examined the final copy of this thesis and recommend that it be accepted in partial fulfillment of the requirements for the degree of Master of Science with a major in Computer Science. ___________________________________ Dr. Mina Sartipi, Chairperson We have read this thesis and recommend its acceptance: _________________________________ Dr. Billy Harris _________________________________ Dr. Li Yang Accepted for the Graduate Council: ___________________________________ Interim Dean of the Graduate School Dedication I would like to dedicate this master’s thesis and my master’s degree to my parents. Without their support neither would be possible. i Abstract In this thesis, we introduce TinyTermite. TinyTermite is a novel probabilistic routing algorithm that is secure against selective forwarding and replay attacks. We use suspicion pheromone to build a flexible map of possible compromised neighbors. As suspicion builds up and decays for each neighbor, TinyTermite is able to deal with uncertain stimulus and react properly. TinyTermite is fully implemented on TinyOS based Intel Mote 2 platform and the experiments were done to compare its performance with that of the traditional Termite algorithm. The experimental results show that TinyTermite is significantly more secure against replay and sinkhole attacks by lowering the packet loss from 88.5% to 32.9% with 12.7% normal packet loss. The experimental results also demonstrate that the TinyTermite provides high throughput and low latency.

  • Implementation and Testing of Loadng: a Routing Protocol for WSN
    Bachelor of Science Thesis Telecommunication Engineering Implementation and Testing of LOADng: a Routing Protocol for WSN by Alberto Camacho Martínez Directed by: Thomas H. Clausen Paris, 2012 To my family Abstract The Wireless Sensor Networks is an emerging technology with strong poten- tial in a wide range of fields. Data acquisition, connectivity, and monitoring are real demand services in constant growth in which sensor networks can take an important role. Routing protocols for wireless sensor networks must be developed to sat- isfy the needs of the applications and to adapt to the limited sensor nodes resources. The current standardized routing protocol for Wireless Sensor Networks, RPL, has been proved to be inefficient in some scenarios and for certain traffic patterns. There is a need to develop routing protocols adapted to the traffic patterns in which RPL is not optimized. The work collected in this manuscript contributes in the developing process of a routing protocol for wireless sensor networks, LOADng [32], which was submitted as an IETF internet-draft during the elaboration of this thesis. The description of LOADng draft is presented in chapter 3. A LOADng implementation has been written and integrated into Contiki OS, an operating system for sensor nodes and other embedded systems. This implementation is documented in chapter 5. During the development of this work, some interoperability tests were made in cooperation with HIPERCOM, Hitachi YRL, and EDF. The results were satisfactory and are published in [10]. The results of the simulations testing LOADng implementation – and per- formance – for Contiki OS are presented in chapter 6 of this manuscript.

  • Routing Protocols in Ad Hoc Networks: a Survey
    Routing protocols in ad hoc networks: a survey Azzedine Boukerche, Begumhan Turgut, Nevin Aydin, Mohammad Z. Ahmad, Ladislau B¨ol¨oni,and Damla Turgut1 Abstract Ad hoc wireless networks perform the difficult task of multi-hop communication in an environment without a dedicated infrastructure, with mobile nodes and changing network topology. Different deploy- ments exhibit various constraints, such as energy limitations, opportunities, such as the knowledge of the physical location of the nodes in certain scenarios, and requirements, such as real-time or multi-cast communication. In the last 15 years, the wireless networking community designed hundreds of new routing protocols targeting the various scenarios of this design space. The objective of this paper is to create a taxonomy of the ad hoc routing protocols, and to survey and compare representative examples for each class of protocols. We strive to uncover the requirements considered by the different protocols, the resource limitations under which they operate, and the design decisions made by the authors. Key words: ad hoc networks, sensor networks, routing protocols 1. Introduction Wireless local area networks based on the 802.11a,b,g and n standards became one of the most ubiquitous ways of networking with mobile nodes. Most of these networks, however, are deployed in the configuration which can be called \wired everywhere, except the first hop". If the goal of the user of the mobile computer is to connect to a website located halfway around the world, the best strategy is to escape as quickly as possible from the challenges of wireless domain and enter the reliability of fiber optic networks and time-tested networking protocols.

  • Performance of Dynamic Source Routing Protocol
    International Journal of Advanced Technology in Engineering and Science www.ijates.com Volume No.03, Issue No. 03, March 2015 ISSN (online): 2348 – 7550 PERFORMANCE OF DYNAMIC SOURCE ROUTING PROTOCOL FOR FIXED AND VARIABLE POWER TRANSMISSIONS IN WIRELESS SENSOR NETWORK N.Divya1, U.Hari2 1PG Scholar, Embedded System Technology, Department of ECE, SRM University (India) 2Asst. Prof, Department of ECE, SRM University (India) ABSTRACT A wireless sensor network consists of collection of sensor nodes deployed over a geographical area for monitoring different parameters. The power source of sensor node consists of a battery with a limited energy and it is impossible to recharge the battery, because nodes may be deployed in an unmanned or remote area. Most of the power is consumed by the radio communication involved in the sensor network. So an energy efficient communication scheme has to be designed to improve the network lifetime. DSR protocol is a reactive protocol that makes it possible for all the nodes to find a route to a destination in a multiple network hops dynamically. The network lifetime reduces by forwarding data with more transmission power. The intermediate nodes spend more energy to transmit its own data and forward other nodes data. Therefore the intermediate node drains out of energy soon. To solve this problem the transmission power has to adjusted for different transmissions in the network according to distance towards the destination. The simulation is done using TOSSIM simulator tool. Keywords: DSR (Dynamic Source Routing) Protocol, Intermediate Nodes, Network Lifetime, Transmission power level, WSN (Wireless Sensor Network I. INTRODUCTION Wireless sensor network (WSN) is the collection of sensor nodes that performs a given task with coordination and in-network processing.

  • Shortcut Tree Routing Using Neighbor Table in Zigbee Wireless Networks
    Shortcut Tree Routing using Neighbor Table in ZigBee Wireless Networks Salmu K.P1, Chinchu James2 1,2Department of Computer Science, IIET, Nellikuzhi Abstract- ZigBee is a worldwide standard for wireless personal area network targeted to low power and cost effective data communications with business and consumer devices. The ZigBee Tree Routing is used in many resource-limited devices and applications. It is not able to require any routing table and route discovery overhead to send a packet to reach the destination. The ZigBee tree routing follows the tree topology. It cannot provide the optimal routing path. The Shortcut Tree Routing (STR) protocol has been provided the near optimal routing path as well as maintains the advantages of ZigBee tree routing that is no route discovery overhead and low memory consumption. The main idea is to provide shortcut tree routing to calculate remaining hops from a source to the destination using the hierarchical addressing scheme. Each source forwards a packet to the neighbour node with the smallest remaining hops in its neighbour table. The shortcut tree routing is fully distributed with ZigBee standard and it utilizes hierarchical addressing scheme. The aim is to find the near optimal routing path with low Route discovery overhead and Low memory consumption. Keywords- ZigBee; tree routing; shortcut tree routing (STR); neighbor table; MANET I. INTRODUCTION ZigBee is the global standards of communication protocol formulated by the relevant task force under the IEEE 802.15 working group. The ZigBee network layer [1] provides dynamic network formation, addressing, routing, and network management functions. Different from the other wireless personal area network standards such as Bluetooth, infrared, and Wireless USB, ZigBee provides the low power wireless mesh and tree networking and supports up to thousands of devices in a network.

Owing to this rapid growth, the deployment of IoT-oriented networks based on mesh topologies is very attractive, thanks to their scalability and reliability (in the presence of failures). In this paper, we provide a comprehensive survey of the following relevant wireless technologies: IEEE 802.11, Bluetooth, IEEE 802.15.4-oriented, and Sub-GHz-based LoRa. Our goal is to highlight how various communication technologies may be suitable for mesh networking, either providing a native support or being adapted subsequently. Hence, we discuss how these wireless technologies, being either standard or proprietary, can adapt to IoT scenarios (e.g., smart cities and smart agriculture) in which the heterogeneity of the involved devices is a key feature. Finally, we provide reference use cases involving all the analyzed mesh-oriented technologies. Keywords: mesh networks; routing algorithms; IEEE 802.11; bluetooth; IEEE 802.15.4; ZigBee; LoRa; smart agriculture; smart city; Internet of Things 1.
