| 摘 要： | 文中针对传感器节点分布不均和拓扑建立时间长的问题,提出了一种基于二分法的拓扑控制算法,每个节点自适应选择发射功率以获得预设的度。仿真显示,与基于均匀功率增量的算法相比,基于二分法的拓扑控制算法大大减少了功率切换次数且形成的拓扑简单,减少了网络拓扑形成时间和平均发射功率。

| Abstract: | A novel topology control algorithm based on dichotomy was proposed aiming at solving the problem of nodes non-uniform distribution and long topology construction time.Each node chooses the transmission power adaptively in order to achieve preset degree.Simulation results show that,compared with the algorithm with uniform power increments,the dichotomy-based algorithm greatly reduces the number of power handoff and gets simpler network topology.Therefore,both the formation time of network topology and the av... |
