摘要
由于当前的无线传感器网络能量均衡路由方法未能考虑最优发射功率问题,导致无线传感器网络能量消耗较多、网络使用寿命较低以及网络节点能量不均衡,因此提出基于拓扑控制的无线传感器节能路由优化方法。将无线传感器节点的功率控制抽象为一个多人的非合作博弈问题,利用节点之间的博弈进行拓扑控制,从而获取最佳发射功率,并将蚁群算法应用于无线传感器网络的路径选择,通过蚁群的动态适应和寻优能力平衡网络最短路径和能量均衡消耗,以达到无线传感器网络能量均衡路由优化的目的。仿真结果表明,所提方法能够有效降低能量消耗,提升网络使用寿命,使无线传感器网络能量达到均衡。
Due to the fact that the current energy balanced routing methods fail to consider the optimal transmission power, the energy consumption of wireless sensor networks is high, the service life of the network is low, and the energy of network nodes is unbalanced. Therefore, energy balanced routing optimization method for wireless sensor networks based on topology control is proposed. The power control of wireless sensor node is abstracted as a multi person non cooperative game problem, and the game between nodes is used to control topology to obtain the best transmit power. On the basis of the above, ant colony algorithm is applied to the path selection of wireless sensor network, and the shortest path and energy consumption are balanced by ant colony dynamic adaptation and optimization ability In order to achieve the goal of energy balance routing optimization in wireless sensor networks. The simulation results show that the proposed method can effectively reduce the energy consumption, improve the network service life, and make the energy balance of wireless sensor network.
