Performance Enhancement in AODV with Accessibility Prediction
Habib-ur Rehman, Lars Christian Wolf · 2007
The need for mobility awareness in ad hoc routing protocols is widely proclaimed. In this paper we present AODV-AP, a scheme to make AODV nodes aware of the accessibility of the neighbor nodes in the network. Nodes acquire the accessibility information of the other nodes through routine routing operations and keep it in their routing tables. later, this information can be utilized to enhance routing operations. One possible use of this accessibility information, restrict the route discoveries for inaccessible nodes, is also evaluated in this paper. Simulation results show that the use of accessibility knowledge in the route discovery process largely reduces the MAC and Routing overhead. Similarly, the Normalized Throughput with respect to MAC overhead is up to 3 times higher than that in standard AODV which reflects the effective use of network resources.
