Problem statement: A Wireless ad hoc network is a collection of autonomous movable nodes that communicate with each other over wireless links without any static infrastructure. In these networks there is no fixed topology because of the mobility of nodes, interference, multipath propagation and path loss. A variety of routing protocols and algorithm with varying network settings are analyzed to link between the nodes and communicate packets to their destinations. Most of these algorithms are single cost, in the logic that they consign a scalar cost parameter to every link and compute the path that has minimum cost. Although multicost routing, a vector of cost parameters is consigned to each link and the cost vector of a path is well-defined based on the cost vectors of the links that embrace it. Adjustable transmission power control of the nodes with multi cost routing algorithm can support optimizeto acquire the reduced interference and improve the ad hoc network performance. Approach: The link and path of the wireless network is consigned with several cost parameters. Hop count, total interference, node link delay, residual energy of a node and the node transmission power are the cost parameters assigned for link and path of the ad hoc networks. Multicost parameters are combined in different optimization function with respect to various routing algorithm. Results: Simulation and optimization shows multicost SUM/MIN Energy-Interference algorithm with variable transmission power can lead to decrease the interference and improves the overall network performance. Conclusion: The function optimized for wireless ad hoc networks that the Multicost SUM/MIN Energy-Interference algorithm achieves improved performance over than the single cost algorithm.
