摘　　要：无线AdHoc网中,公平分配资源和最大化利用资源本质上是冲突的,这对资源分配算法的设计带来了挑战。在系统地分析AdHoc网络的信息流竞争特点的基础上,引入价格作为资源分配的度量指标,通过路由发现时的价格查询以及路由响应时的价格反馈,消除分布式预测带来的不一致性,构建了一种新的基于价格的无线AdHoc网络资源分配算法,对资源分配进行了仿真实验。仿真结果表明:改进的资源分配算法具有良好的收敛性,与现有的资源分配算法相比提高了资源利用率。In wireless ad hoc networks fair distribution of resource and maximization of resource utilization are in conflict in nature, which brings a great challenge for designing resource allocation algorithms. With the analysis of the contest characteristics of ad hoc network information flow, price was introduced to measure resource allocation. Price query was done with the route discovery and price feedback was done with the route reply. It can eliminate the inconsistency of distributed prediction. Then a new price-based resource allocation algorithm of wireless ad hoc networks was proposed. Contrast simulations were done to test resource allocation. The simulation results show that it has good convergence and it improves the resource utility compared to other algorithms.
