Abstract: Hybrid ad hoc networks are a combination of a fixed network, a base station or free standing mobile ad hoc network (MANET). The energy conservation is a major issue in hybrid ad hoc network with limited battery life of mobile terminals. The lifetime of a network will be improved by suitably reducing the requirement of power for connections. This paper proposed a novel energy efficient ad hoc on-demand multipath distance vector (EEAOMDV) routing protocol that uses ad hoc on demand multipath distance vector (AOMDV) routing protocol as a basic routing strategy. The selected route satisfies quality of service in energy stable and the delay constraint on the application. The operation of EEAOMDV has three phases. In the first route discovery phase, the delay and energy constraints are built into the AOMDV route discovery mechanism. During link failure, the second phase is invoked to search for an energy stable alternate path locally. The third phase chooses the optimal path from available multiple paths from source to destination pair in the hybrid network. Simulation was performed to determine the packet delivery ratio, routing overhead, throughput, end-to-end delay and average energy consumption are experienced by varying nodes and pause time.
