Gateway Discovery in Ad hoc On-Demand Distance Vector (AODV) Routing for Internet Connectivity

In this paper, we consider a mobile ad-hoc network (MANET) in which mobile nodes can access the Internet via a stationary gateway node or access point. These gateways act as bridges between a MANET and the Internet. Mobile nodes that are outside the transmission range of the gateway can continue to...

Summary:In this paper, we consider a mobile ad-hoc network (MANET) in which mobile nodes can access the Internet via a stationary gateway node or access point. These gateways act as bridges between a MANET and the Internet. Mobile nodes that are outside the transmission range of the gateway can continue to communicate with the gateway via a multi-hop connection with their neighboring nodes. Ad hoc on-demand distance vector (AODV) ad hoc routing protocol was modified to support mobile devices in ad hoc networks to communicate with fixed device in the Internet. Thus, the problem of applying the modified AODV routing to MANET is considered in this paper. Network Simulator 2, NS 2 with Trace Graph 2, has been used to analyze the network under different scenarios (different topology , number of gateways , number of traffic sources and max speed of mobile nodes). Three proposed approaches for gateway discovery are implemented and investigated. Also, the effect of the mobile terminals speed and the number of gateways on the network performance are studied and compared.
