Ad hoc networks are used where wired network and mobile access is either unproductive or not feasible. They are infrastructure-less networks formed with limited life of existence. As adhoc networks change their topology frequently, routing in such networks is a challenging task. Moreover, bandwidth, energy and physical security are limited in these kinds of networks. In this paper, the reactive protocol—Ad hoc On Demand Vector (AODV), proactive protocol —Optimized Link State Routing (OLSR) and hybrid routing protocol—Zone Routing Protocol (ZRP) are evaluated for energy consumption for TCP and CBR traffic pattern. NS-2 simulator is used for performing all the simulation works.

 
 
 

Ad-hoc networks, the key factors in the wireless communication, seemed to be the future generation wireless networking. A Mobile Ad Hoc Network (MANET) is a group of autonomous mobile nodes connected by means of wireless links without having any backbone infrastructure. The system may operate in isolation or having gateways to interface with a fixed network (Singla et al., 2009; and Singla and Kakkar, 2010). The nodes in the network acted as hosts and also as routers that route data to other nodes in network. A few possible examples where MANET networks are useful include: earthquake hit areas, where infrastructure is destroyed; military soldiers in a destructive environment; virtual classrooms; biological detection; tracking of rare animals; space exploration; and undersea operations. In MANETs, a routing mechanism is always required to search a path for forwarding the packets between the source node and the destination node. In MANETs, energy consumption is an important issue as most mobile nodes operate on limited battery resources (Alsaadi and Qian 2007; and Ghosekar et al., 2010).

The paper is organized as follows: first, the paper briefly discusses the routing protocols that are evaluated in the next sections. Then, it compares the energy-based different routing protocols for CBR and TCP traffic. Finally, the paper ends with conclusion.
