摘要 CDMA无线Ad Hoc网络节点间的并发信息传送所造成的节点间相互干扰是影响网络传输性能的主要因素之一.文中从CDMA无线Ad Hoc网络的节点间的信息流量角度研究了CDMA无线Ad Hoc网络的传输性能和吞吐量性能,以节点间信息事件图为工具研究了节点间干扰对网络传输性能的影响,并证明了节点间信息流量成功传输的一个充分条件,最后对结果进行了仿真并给出了节点间信息流量的一个拟合方程. The transmission capacity of CDMA mutual interference of concurrent transmissions Wireless Ad Hoc Networks is constrained by the among nodes. This paper studies the transmission capacity and throughput of CDMA Wireless Ad Hoc Networks from the view of the information flux among nodes, and makes a research on the impact of interference among nodes on transmission eapacity of networks. The paper concludes and proves a sufficient condition to support the successful transmissions among nodes, and at last, some simulations is given and the validity of the results of paper is testified and a fit equation for information flux among nodes also is proposed.
