Energy Consumption in Unipath and Multipath MANET Routing Protocols under CBR and VBR Traffic Models

A Mobile Ad hoc Networks (MANET) represents a system of wireless mobile nodes that can freely and dynamically self-organize in to arbitrary and temporary network topologies, allowing people and devices to seamlessly communicate without any pre-existing communication architecture. One of the main issues in MANET routing protocols is development of energy efficient protocols due to limited bandwidth and battery life. There are various such protocols developed and analyzed under Constant Bit Rate (CBR) traffic by many authors. The present communication is an attempt to identify the energy consumption packets in traffic models (CBR and VBR) using unipath routing protocol AODV and multipath routing protocol AOMDV.  Simulation and computation of energy consumed, received and transmitted energy were done with ns-2 simulator (2.34 version) with parameter variation: number of nodes, pause time, average speed.
