Abstract
This paper proposes AM-AOMDV, a novel multi-metric and multipath reactive routing scheme for wireless ad hoc networks. The AM-AOMDV extends the AOMDV scheme by including a multiple route metrics, a novel local route update and route maintenance algorithm. The algorithm uses the one-hop information exchange between neighboring nodes to increase the packet throughput and route longevity, decrease the end-to-end latency, route discovery frequency and route overhead under high mobility environments. The multiple metrics (i.e., node-to-end latency, node-to-end RSSI, and node occupancy) allow the routing scheme to converge to the most efficient route during the data transmission period and hence avoid the creation of hotspots under heavy traffic conditions. Simulations are carried out in ns-2 and the results are compared to the AOMDV protocol. The results show that the AM-AOMDV outperforms the AOMDV protocol in terms of the above discussed performance metrics.
