摘要
针对无线网络的多用户接入问题,提出了信道负载估计的迭代算法。对于采取动态接入概率机制的无线网络,中心节点根据文中提出的迭代算法,能够快速而精确的估计出信道负载,从而通过下行广播信道对终端用户的接入概率进行控制,达到提高信道吞吐率,降低分组时延的目的。
An algorithm of load estimation based on iteration algorithm has been proposed in this paper to solve the multi-user problem in wireless networks. In those using DAP(dynamic access probability) protocol, the centre node can accurately and quickly compute the load on shared channel with the iteration algorithm, to control the access probability of all users' in the system through the down-link broadcast channel.
