PhD Research Title: A new Techniques to Improve the Route Discovery Process for On-Demand Routing Protocols.
The most important feature of MANETs is the mobility support that allows mobile nodes to move freely within a network’s geographical area. The nodes’ movements have varying speeds and patterns and these can cause link and route disconnections. In turn, this can significantly degrade an employed routing protocol’s performance. In addition, mobile nodes in MANETs suffer from limited power supplies and any receiving or transmitting of data affects their battery levels. Therefore, mobile nodes must conserve their batteries for necessary communications and should not waste them on duplicate processes such as flooding in the network.
The aim of y project is to resolve some of the issues found in Mobile Wireless Ad-hoc Networks, especially in on-demand routing protocols such as AODV and DSR that find end-to-end routes between network nodes to enable communication. This work introduced three new route discovery techniques that improve the overall level of overhead and offer a better experience during communication with regard to Network Lifetime, Throughput, Data Drop and Delivery Ratio.
