摘要
为了提高移动通信网络的覆盖能力,提出一种基于自适应分层路由探测的移动通信网络通信节点拓扑定位方法。采用Sink节点分组协调机制进行通信网络负载均衡控制设计,同时采用最短收发路径寻优方法进行通信节点的自适应组网设计,计算网络链路节点的正确传递概率密度函数,求解其最优值,以此为优化目标进行分层路由探测,实现通信节点拓扑定位。仿真结果表明,采用该方法进行通信节点拓扑定位,提高了移动通信网络的覆盖度,以最少的节点实现最大范围的通信覆盖。
A topological positioning method of communication node in the mobile communication network is proposed to improve the coverage capacity of the mobile communication network, which is based on adaptive hierarchical routing detection. The Sink node grouping coordination mechanism is adopted to achieve balance control design of communication network load. The adaptive networking design of communication nodes is conducted by means of the shortest transceiving path optimizing method. The probability density function for correct transmission of the network link node is calculated to solve the optimal value, so as to optimize the hierarchical routing detection to realize the topological positioning of communication node. The simulation results show that the proposed method can improve the coverage capacity of mobile communication network and achieve the maximum communication coverage with the least nodes.
