Efficient Routing Path Selection Algorithm based on Pricing Mechanism in Ad Hoc Networks

Abstract

In military and rescue applications of mobile ad hoc networks, all the nodes belong to the same authority； therefore, they are motivated to cooperate in order to support the basic functions of the network. However, the nodes are not willing to forward packets for the benefit of other nodes in civilian applications on mobile ad hoc networks. In view of this, we adopt the “pay for service” model of cooperation, and propose a pricing mechanism combined with routing protocol. The scheme considers users’ benefits and interference effect in wireless networks, and can distribute traffic load more evenly to improve network performance. The simulation results show that our algorithm outperforms other routing protocols. Using our pricing mechanism and routing protocol at the same time can achieve more economical efficiency.
