无线传感器网络在获取重要数据信息时,为了将获得的有用信息,从源节点以最小的能量消耗传输到目标节点,以提高网络的使用寿命,本文结合能量消耗在无线传感器网络的具体特点,在无线传感器网络中引入蚁群算法,提出了基于蚁群算法的能量均衡的无线传感器网络路由方法。算法中通过蚁群理论以寻找源节点到目标节点过程中能量均衡的最优路径,并对路径中的信息素进行不断更新;此外对适应度函数进行了改进,并将节点间路径长度与剩余的节点能量作为其参数。仿真结果表明,本文算法与传统的ACO等算法相比,能够同时兼顾路径长度与节点能量消耗,网络能耗均低于传统算法下的网络能耗,大大增加了网络的使用周期。
In order to get the useful information from the source node to the target node with minimum energy consumption, the wireless sensor network can improve the service life of the network. In this paper, according to the specific characteristics of the energy consumption in the wireless sensor network, The ant colony algorithm is introduced into the wireless sensor network, and the energy equalization routing algorithm based on ant colony algorithm is proposed. In the algorithm, the ant colony theory is used to find the optimal path of energy balance between the source node and the target node, and the pheromone in the path is continuously updated. In addition, the fitness function is improved and the path length and residual The node energy as its parameter. The simulation results show that compared with the traditional algorithms such as ACO, the proposed algorithm can take both path length and node energy consumption into account. The energy consumption of the network is lower than that of the traditional algorithm, which greatly increases the service life of the network.
