A new metric, processing delay, has been proposed for route path selection. Processing delay, proposed by G. Bianchi, (2000) is used to calculate the performance of each node along the route. The function takes into account the number of active nodes in the vicinity of the forwarding node. Simulation experiments which have incorporated the new metric into the on-demand mobile ad hoc network protocol, dynamic source routing (DSR), have shown that the new metric has the characteristics of spreading the routes among the nodes in the network, thus minimizing congestion. The performance of the new on-demand ad hoc network, enhanced-DSR (eDSR), has shown a 20% reduction in packet delay, with marginal increase in hop counts
