Performance evaluation of improved reliable DSR protocol in case of node failure

A new approach is introduced to obtain the reliability function of time-dependent system by using reliable node and reliable path concept in mobile ad-hoc network (MANET). It is known that all nodes of the MANET are not functional at all the time. Upon the failure of any node in the active path of the network, the system switches to the next path and correspondingly the connection between the source and the destination is established. Here, reliable node model is used to evaluate the performance and reliability of MANET. The model is simulated using NetSim software and performance analysis is carried out. The efficiency of the proposed protocol has been evaluated on different scenarios and there has been a noticeable improvement in the throughput and also in the reduction of end-to-end delay.
