基于CDMAAd hoc网络的市场资源分配方案

An Approach of Resource Allocation of ad hoc Network Based on CDMA and Market

在无线通信中,最常用的通信方式有TDMA、FDMA、CDMA。其中,CDMA因为其抗干扰性好、辐射小、接通率高、系统容量高以及保密性好,所以是最好的选择。本文分析了采用CDMA通信方式的分簇结构的ad hoc网络,采用市场理论的方法,根据供需协商的原则,对资源进行最优分配。分析结果表明,这种分配方案能实现各簇收益最大,能有效提高系统资源效用,并且提高系统实际通信容量。

In wireless communications system, TDMA, FDMA and CDMA are most commonly used,Because the anti-interference capability of CDMA is strong and its flexible application., radiation effects is small, percentage of successful connections is presented., and can improve system capacity dramatically,CDMA is the best choice. This paper analyzes the approach which is used in Ad Hoc network that based on CDMA Communication Mode,and the applications of clustering structure.Market theory is used in this approach, the optimal allocation of resources is based on the principle which focus on balance of Supply and Demand. The results show that this allocation approach contribute to the maximum benefits in every cluster,and making full use of systematic resources of the ad hoc network, and has huge communication capacity.
