Mobile ad-hoc networks (MANETs) are recently attracting a lot of interest due to their widely available wireless devices and low communication cost. MANET comprises a set of wireless communicating devices able to connect instantaneously without any pre-existing base station. Due to a limited transmission range of mobile devices, they need multi-hop routing for communication. In MANET nodes can change topology in an unpredictable manner so they need an efficient routing protocol which can handle the changing topology. However, MANET suffers from many challenges, including decentralization, low memory device, infrastructure less, bandwidth and limited battery reservoir. Different modes of the nodes like active-communication mode and non-active-communication mode consume available energy of a node. This paper presents an energy measurement model which shows the remaining energy level in each mobile node after some activity. The parameters required for designing energy measurement model consist of initialEnergy, txPower, rxPower, and idlePower. This paper also evaluates the performance measure metrics of two routing protocols such as Ad hoc On Demand Distance Vector (AODV) and Destination Sequenced Distance Vector (DSDV). This paper analyzes these routing protocols by simulation tested in network simulator (NS2). The performance will be studied based on Throughput, Packet loss, Routing delay, Cumulative sum of dropped packets, Calculate energy consumption and remaining energy at each node.
