无线Ad hoc网络网络中的节能技术已经成为研究领域中的一个热点。采用随机功率控制的无线Ad hoc网络,节点之间成功传输概率及网络能耗与各节点发射功率的概率分布有关,分析并仿真了分别采用均匀分布、正线性分布、负线性分布、凸三角(类高斯)分布和凹三角分布的随机功率控制策略对Ad hoc网络通信成功概率和网络能耗的影响。结果表明采用正线性分布和类高斯分布的随机功率控制具有较优的性能。
Energy-saving technologies in wireless Ad hoc networks have become a hot area of research. Adopting random power control in wireless Ad hoc networks, the probability of successful transmission between nodes and the network energy consumption is related to the probability distribution of the transmission power of each node. The distributions of the power distribution of each node, including the uniform distribution, positive linear distribution, negative linear distribution, Gaussian distribution and concave triangular distribution of random power control strategy on the probability of communication success and network energy consumption in Ad hoc networks. The results show that the stochastic power control with positive linear distribution and Gaussian distribution has better performance.
