Please let me know of any Formatted that I have missed. This document is very much a work in progress. So let’s have some discussion. While everything in this document is a subject for discussion, some parts are highlighted in particular as a discussion point] C802.20-03/43 (& 03/57) has a detailed proposal for traffic models for Web-browsing, FTP, WAP, and near real time video. C802.20-03-13r1 details a user modeling approach including a Web/interactive user/capacity model. C802.20-03/35 gives a list of MBWA traffic types. C802.20-03/53 shows a measurement of the mix of traffic types. C802.20-03/46r1 states that a mix of narrowband of broadband traffic types should be used] 1 Overview 1.1 Purpose This document specifies a set of mobile broadband wireless traffic models in order to facilitate the MBWA system simulations. 1.2 Scope The scope of this document is to define the specifications of mobile broadband wireless traffic models. 1.3 Abbreviations and Definitions FTP = File Transfer Protocol HTTP = Hypertext Transfer Protocol MBWA = Mobile Broadband Wireless Access TCP = Transmission Control Protocol UDP = User Datagram Protocol VoIP = Voice over IP WAP = Wireless Application Protocol 2 Traffic Modeling for MBWA Simulations 2.1 Introduction The Mobile Broadband Wireless Access (MBWA) systems being discussed in IEEE 802.20 standards group are designed to provide a broadband, IP-oriented connection to a wireless user that is comparable to wired broadband connections that are in use today. It is expected that there will be a mix of user 5 Deleted: June {Sept 13, 2003} IEEE P802.20-PD<number>/V<number> Deleted: 9 applications, not unlike that of such wired systems. Further, the traffic characteristics and system Deleted: i requirements of the various applications can vary widely. The performance of such MBWA systems is thus very much dependant on the details of the applications and their traffic models. This is in contrast to cellular wireless voice systems where the performance studies focused on physical and link layer performance with a relatively simple traffic generation model. The purpose of this document is to provide detailed statistical traffic models which can be used as an input to generate packets in a simulation study of a MBWA system. It will be a companion to the detailed statistical channel models which specify the wireless transmission channel impairments. 2.2 Context and Scope 2.2.1 User scenarios There can be various different user scenarios for MBWA systems, some of which we cannot foresee at this time. For purposes of illustration, we include some candidate scenarios to frame the context of our work. In Deleted: [Editor’s note: These all cases, the MBWA modem can either be built-in or supplied

Sterbenz: Chairperson Dr. Gary Minden Dr. Fengjun Li Date Approved i Abstract Mobile Ad Hoc networks (MANETs) present unique challenge to new protocol design, especially in scenarios where nodes are highly mobile. Routing proto- cols performance is essential to the performance of wireless networks especially in mobile ad-hoc scenarios. The development of new routing protocols requires com- paring them against well-known protocols in various simulation environments. The protocols should be analysed under realistic conditions including, but not limited to, representative data transmission models, limited buffer space for data transmission, sensible simulation area and transmission range combination, and realistic moving patterns of the mobiles nodes. Furthermore, application traffic like transactional application traffic has not been investigated for domain-specific MANETs scenarios. Overall, there are not enough performance comparison work in the past literatures. This thesis presents extensive performance comparison among MANETs comparing transactional traffic including both highly-dynamic environment as well as low-mobility cases.

In partial fulfillment of the requirements for the degree of Masters of Applied Science --------------------------------------------------------------------------- Chair, Dr. H.M. Schwartz, Department of Systems and Computer Engineering --------------------------------------------------------------------------- Thesis Co-supervisor, Dr. Marc St-Hilaire --------------------------------------------------------------------------- Thesis Co-supervisor, Dr. Chung-Horng Lung Carleton University May 2010 iii Abstract In order to overcome the known challenges (i.e., latency, jitter, packet loss, and etc.) of transmitting multimedia traffic over a packet switched network, careful network planning needs to take pace. Existing simulation platforms, particularly for Voice over IP (VoIP) simulations, have available a limited selections of speech encoding algorithms. The primary objective of this thesis is the creation of a tool aimed at supporting the planning and design phases of packet switched networks carrying voice traffic while considering realistic and current network conditions and simulation features. More specifically, this thesis focuses on the creation of a speech background traffic generation models with the purpose of generating traffic that follows the behaviour of a number of speech encoding algorithms.
