Abstract


Wireless mobile ad hoc networks (MANETS) are self configuring, dynamic networks in which nodes are free to move. In mobile ad hoc networks, the major performance constraint comes from path loss and channel fading. This project implements a channel adaptive routing protocol which extends the Ad hoc On-Demand multipath Distance vector (AOMDV) Routing protocol to accommodate channel fading. This channel aware AOMDV routing protocol uses the channel average non fading duration as a routing metric to select stable links for path discovery and senses the channel to avoid channel fading by applying a preemptive handoff strategy before a fade occurs. This channel aware AOMDV routing protocol maintains reliable connections by exploiting channel state information. Using the same information about the channel, paths can be reused when they are available rather than discarding them completely. This Channel aware AOMDV routing protocol will be implemented in heterogeneous network.
