A mobile ad hoc network is a collection of wireless mobile hosts forming a temporary network without the aid of any centralized administration or standard support services regularly available in wide-area networks to which the hosts may normally be connected In this paper, we present an effective scheme to balance the load in ad hoc network. The scheme can be applied in most on-demand routing protocols. It is implemented in the process of route request. When route request (RREQ) messages are flooded to acquire routes, Only the qualified nodes, which have a potential to serve as intermediate forwarding nodes, will respond to these messages, so that the established path will not be very congested, and the traffic will be distributed evenly in the network. In this scheme, a threshold value, which is used to judge if the intermediate node is overloaded, is variable and changing along with the nodes’ interface queue occupancy around the backward path. Therefore, we call it an adaptive load-balancing approach and the performance of routing overhead and average end-to-end delay is also improved.
