Abstract: Mobile Ad-hoc Network (MANET) is consisting of independent wireless mobile nodes which animatedly form a temporary network without use of any fixed infrastructure or centralized management. A major anxiety that affects such a network that characterized by dynamically changing topology is the performance, where routing with robustness performance is one of the key challenges in deploying MANET. In this work we concentrate on AODV routing protocol which is widely used in MANET, It is widely simulated in this paper by varying number of nodes in MANET for standard AODV routing protocol and modified AODV which will take forwarding decision based on two parameters that are energy of node and link expire time (LET) and scrutinize the impact on network stability. Routing protocols are analyzed against several performance metrics. Modified AODV employs a novel route discovery process that takes into account the links stability and the nodes residual energy to perform data routing.
