Abstract
A mobile wireless Ad hoc network (MANET) is formed dynamically without a need
for a pre-existing infrastructure. This kind of dynamic networks has been used in commercial,
cultural, and environmental applications including emergency situations. This paper addresses the
problem of the overhead resulting from flooding the control packets in mobile ad hoc networks in
searching for routes between the source and destination. We propose a location enhanced routing
protocol for clustered MANETs based on the cluster based routing protocol (CBRP). Our protocol
employs local position information obtained by smart antennas to discover routes and make
routing decisions for the clustered MANETs. Simulation results shows enhancing the performance
of clustered MANETs. Simulations show the packet delivery ratio increased, the delay decreased
and the control packets overhead decreased.
