Abstract
The Dynamic Source Routing Protocol (DSR) is one of the most reliable and effective protocols in the
Mobile Ad Hoc Networks (MANETs). It is also one of the few MANET protocols whose routing scheme
can easily be optimized. But the routing overhead generated by its routing algorithm still leaves substantial
amounts of energy being wasted. Route Request (RREQ) and Route Maintenance packets generate
overhead control packets that occupy bandwidth, consume energy and may overwhelm a network if not
controlled. This paper proposed EEDSR, an extension of DSR that reduces routing overhead by limiting the
number of route discovery and maintenance packets in the MANET. The scheme involves bigger packet
headers for the source route discovery packets since they contain information about the energy levels of the
nodes in the route cache. In EEDSR, since the RREQ packets are flooded once for each communication
period, routing overhead is minimized.
