Performance Evaluation of Load Based Channel Aware Routing in MANETs with Reusable Path

Mobile Ad Hoc Networks (MANETs) are wireless networks which don't require any infrastructure support for transferring the data packet between two nodes. Routing protocols for ad hoc networks has generally ignored channel fading. The existing protocol Channel Aware - Ad hoc On-demand Multipath Distance Vector (CA-AOMDV) uses one of the routing metrics as channel Average Non-Fading Duration (ANFD). This metric is useful for informing the fading detail into neighbour node. We proposed a new Load Based Channel Aware - Ad hoc On-demand Multipath Distance Vector (LBCA-AOMDV) protocol which is applied for load balancing to improve the network performances. In our routing protocol calculates the channel's non-fading duration for routing with minimum packet loss. Specifically, the faded paths can be reused rather than being discarded and also the loads are balanced on the link. The NS-2 was used to perform both simulation and performance evaluation of the proposed protocol and to compare it with the existing protocols. The simulation result demonstrates the greatly improved network performance and reduction of packet loss on routing over CA-AOMDV.
