Adaptive Threshold Routing Algorithm with Load-balancing for Ad Hoc Networks

Routing algorithm is a challenge for a mobile ad hoc network (MANET), but current routing protocols for MANET consider the path with minimum number of hops as the optimal path to a given destination. This strategy does not balance the traffic load over a MANET, and may result in some disadvantages such as creating congested area, depleting power faster and enlarging time delay in the nodes with heavy duties. In this paper we proposed routing metric can reflect not only the load of the path, but also the load distribution along the path. Simulation results show effectiveness of the routing scheme on balancing the load over all nodes in the network. Index Terms—Ad hoc, Load balance, Thershold value
