A Fault Tolerant Power Constraint AODV Protocol for MANET

The rapid development in the wireless technology, enormous availability of mobile devices make the people expectation of their communication with each other without any interruption. Mobile Adhoc Network is a collection of mobile devices which communicate with each other without any infrastructure. The communication networks suffer due to frequent changes in topology because of mobility and scalability. The main objective of this protocol is to resoleve this issue by proposing an enhanced reliable,fault tolerant routing protocol for MANET based on the reactive routing protocol AODV, and is called Fault Tolerant Power Constraint Adhoc On Demand Distance Vector Routing (FTPC-AODV). The proposed FTPC-AODV deals with how the mechanism adapt to topology changes due to mobility induced link break by building back up paths between the source and destination by considering battery power as a constraint. If the primary path fails, it automatically switches to the backup path and improves the data transfer rate. The protocol is implemented using Network Simulator (NS-2) and simulation results are analyzed based on the quantitative metrics. The derived results shows that the performance of Adhoc Newtork significantly improved by means of good packet delivery ratio, through put and reduced packet loss, and delay.
