MANETs are ad hoc multi hop networks, formed of mobile battery chargeable devices and commonly used in emergency situations. With its dynamic topology and limited energy level they often come across with link breaks. This paper analyzes how energy consumption of the mobile devices and density of mobile nodes affects the performance of MANET. AODV and AOMDV are reactive routing protocols used in MANET which handles link break due to node mobility and energy drain. Performance of AODV and AOMDV is analyzed in presence of link breaks using ns2 simulator. The results show AOMDV has better performance in throughput, end to end delay and packet delivery ratio compared to AODV only in presence of large network size and high mobility of nodes.
