摘　　要：对现有抑制网络中干扰信号强度的方法进行了研究,针对抑制干扰的同时也限制了网络的传输容量的问题,提出在无线Ad-hoc网络中设置保护区域来抑制干扰,并推导了最优保护区域的半径。理论分析和仿真结果表明,设置保护区域能够极大程度降低网络中的干扰信号强度,合理地设置保护区域大小能有效提高传输容量,并且保护区域半径存在一个最优值,能使得网络的传输容量达到最大值。The existing methods for suppressing the strength of interference signals in the networks can suppress interference signals effectively but they cause a limit to the transmission capacity of the networks at the same time. To solve this problem, a method of setting guard zone in wireless Ad-hoc network is proposed to suppress interference and the optimum radius of guard zone is derived. Theoretical analysis and simulation results show that the proposed method could greatly reduce the level of interference signal and reasonable radius of guard zone could increase the transmission capacity. The transmission capacity will reach maximum due to an optimum radius of guard zone.
