Reactive Gateway Discovery Routing in Hybrid MANETs

Abstract

Hybrid MANETs enables mobile nodes to access internet services, and is achieved through gateways which act as bridges between a MANET and the Internet. A gateway discovery mechanism enables a mobile node to communicate with an Internet. The reactive gateway discovery routing is based on modified AODV routing protocol, so that in this paper a modification to NS2 has been adjusted to support a modified Ad-hoc On Demand Distance Vector (AODV) routing protocol called AODV+ to integrate MANET with Internet using a stationary gateway. Due to the dynamic nature of MANET, the changes in topology are very frequent and the task of routing the data turns out to be a challenging. Hence, in this paper the performance of modified AODV has been evaluated according to three performance metrics: Discovery time, End-to-end delay and Number of dropped packets under different mobility models and varying maximum speed for different number of nodes.
