Experimental evaluation of a wireless ad hoc network

We experimentally evaluate the performance of a wireless ad hoc network from the point of view of both the routing and transport layers. The experiments are done on a testbed with desktop PCs and laptops using wireless radio LAN interfaces. For these experiments an on-demand routing protocol called AODV (ad hoc on-demand distance vector) has been implemented as a part of the operating system protocol stack. We describe our design choices and the experimental setup. The performance evaluation reveals that the performance is poor beyond two hops at moderate to high loads.
