摘要: 针对无线小区自组织网络节点连接性不高的问题，在网络节点所处的平面上引入空间约束机制，通过加入位置信息和增大平面以降低网络节点间干扰的方法来减小网络总干扰。分析了网络源节点的广播成功率，计算了网络节点的空间位置下界，并分别就单数据流和多数据流的情况下网络的有效性加以讨论。实验仿真表明，这种新型的网络拓扑控制方法可以有效提高无线自组织网络的相关性能。

Abstract: This paper adopted space restrain mechanism in the plain of network nodes due to the lower performance of connectivity in wireless cellular Ad hoc networks, and the total interference of the networks is decreased by considering location information and increasing the plain to lower the co-interference between the nodes. The broadcast success ratio is analyzed, the lower bound of the space location for the network nodes is computed and the efficiency of the network under single-flow and multi-flow environments is discussed separately. The simulation results show that the novel method can improve the performance of the networks significantly. -
