A Multi-channel and Power Controlled Based AODV for Throughput Improvement in Multi-hop Ad Hoc Networks

We propose a solution which aims at improving the throughput in multi-hop ad hoc networks. This solution equips nodes with multiple radio interfaces and dedicates a separate radio channel to each. It firstly assigns channels to transmission links so as nodes receive and emit data simultaneously. Then it enhances the routing protocol so that it takes into account both the channel diversity and the channel alternation while choosing the routes. Finally, it adapts the node transmission power in order to favor the channel re-use in each group of nodes that shared the same channel. We detail its principle while it operates with the AODV routing protocol. Analysis of simulation results prove that such an enhanced AODV protocol performs better than existing metrics such as WCETT and can provide a 370% throughput gain.
