A Mobile Ad Hoc network (MANET) is a collection of digital data terminals that can
communicate with one another without any fixed networking infrastructure. Since the
nodes in a MANET are mobile, the routing and power management become critical
issues. Wireless communication has the advantage of allowing untethered communication,
which implies reliance on portable power sources such as batteries. However, due to the
slow advancement in battery technology, battery power continues to be a constrained
resource and so power management in wireless networks remains to be an important
issue. Though many proactive and reactive routing protocols exist for MANETs the
reactive Dynamic Source Routing (DSR) Protocol is considered to be an efficient
protocol. But, when the network size is increased, it is observed that in DSR overhead
and power consumption of the nodes in the network increase, which in turn drastically
reduce the efficiency of the protocol. In order to overcome these effects, in this paper it is
proposed to implement overhead reduction and efficient energy management for DSR in
mobile Ad Hoc networks.
Key words: MANET, DSR, Energy Management, overhead reduction.
An Ad Hoc network is a collection of wireless mobile
hosts forming a temporary network without the aid of any
established infrastructure or centralized administration .
The absence of any fixed infrastructure, such as access points,
makes Ad-Hoc networks prominently different from other
wireless LANs. In such an environment each node may act as
a router, source and destination, and forwards packets to the
next hop allowing them to reach the final destination through
