They need to the location information of nodes in information to the nodes in the ad hoc networks. It is supposed the network. Every node finds its location by GPS. that there are different clusters in the different levels. Every A source node uses the location service to find the location cluster has a cluster head. The clusters can be logical or physical. The higher level cluster heads have the information of of a destination node and puts it into the header of the data the tables of lower level cluster heads. The information of tables packets. every node routing decision is based on the location of a cluster head is updated periodically by its lower level cluster of destination node and the neighbor nodes. The location heads. The combination of the cluster and position based based routing protocols do not need to create or support the routing can be used. In this paper the cluster and position based routes. The nodes do not need to the routing tables and the location service is represented, that every node can find the updating packets. There are different location services like the location of its destination node via the location service. Some square location service or simple location service. The section nodes are selected as the mirror nodes of a cluster head which 2 surveys the MAODV multicast protocol and the section 3 can act as the cluster head after the failing of cluster head. These reviews the cluster based position service and the section 4 nodes have the replicated information of a cluster head. Here a represents the proposed location and cluster based fault multicast protocol is proposed that a source node can get the tolerant location service then the proposed cluster and position location information of the destination nodes via the proposed based multicast protocol (CPMB) is represented. In continue location service and puts this information into the header of the simulation results are shown, which show that the packets and sends them toward the destination nodes. The proposed multicast protocol has more packet delivery than the simulation results show that the proposed Cluster and Position AODV. [1], [2], [3], [4], [5], [6] based Multicast protocol (CPMB) has more packets delivery ratio and packets transfer ratio than the Multicast Ad hoc II. MAODV PROTOCOL On-Demand Distance Vector multicast protocol (MAODV). The MAODV is a demand based routing protocol that the Keywords —Ad hoc network; position service; fault tolerant; necessary routes are discovered. The MAODV has the least cluster; protocol. control and processing overhead and the multi hop capability and saves the topology dynamically and avoids the loops. I. INTRODUCTION Because of the limited resources of an ad hoc network, the An ad hoc network consists of some wireless mobile nodes MAODV tries to minimize the control overhead by limiting which route the packets without any infrastructure. The ad hoc the updating packets. To minimize the processing overhead, network is divided to static and dynamic ad hoc networks. In a the MAODV packets are simple so they need a little static ad hoc network, the location of a node does not change. computation. MAODV uses the sequential numbers to prevent In the dynamic ad hoc networks the nodes are moving like the the loops. In MAODV, every node has a routing table which mobile and vehicle ad hoc networks. The topology of the consists of information of the routes. Every entry of the mobile ad hoc network is changing. There are two kinds of routing table consists of destination IP address and the routing, the first one is the topology based routing and the sequential number and the number of hops toward the second one is the location based routing. The topology based destination node and the next hop toward the destination node routing use the information of links of the network to transfer and the time to live (TTL) field. When the information of a the packets. They are divided to the table-driven and the route is entered in the routing table, the TTL field for demand based routing protocols. The table-driven routing destination node, will be set based on the RREQ (route protocols consist of the distance-vector protocols and the request), RREP (route reply) or the hello packets. link-state protocols.
