Improved Routing Performance using Bandwidth Estimation in MANET

Mobile Ad hoc Networks (MANETs) are dynamically formed, infrastructure-less, flexible networks. The performance deteriorates due to the unstable traffic conditions, network connectivity issues, mobility and limited resources. To increase MANETs performance metrics, various cross-layering approaches are performed where different OSI layer information are exchanged. Studies have shown that AODV is a most suitable distance vector proactive routing algorithm. In my research a modified version of AODV routing protocol, based on route discovery is investigated by using Physical Layer information instead of the minimum hop count method of the default distance vector algorithm. Altering the interactions between layers by cross layering has been shown to increase performance in certain scenarios of MANETs. This makes a way to cross-layer approach. In the proposed scheme, AODV protocol is used to exploit physical information such as bandwidth at the MAC layer in order to find out the suitable route for different application data. It will be proved that cross- layering between MAC and Network layer outperforms much better than using MAC and Network layer in OSI layer separately.
