为了提高光纤光栅网络的生存周期,进行总线拓扑结构优化节能设计。针对最大角度路由算法进行网络局部能量均衡控制容易导致能量衰落和网络接收失败的问题,提出一种基于最小跳数路由算法的光纤光栅网络总线拓扑结构节能设计方法。采用链路能量均衡约束控制方法进行网络总线拓扑结构总体设计,根据网络拓扑的鲁棒性系数进行全网能量均衡设计,综合考虑网络的能量均衡和节点的通信负载,设计最小跳数路由算法,以网络链接中消耗的能量最小为代价函数进行总线拓扑优化设计。仿真结果表明,采用该方法进行光纤光栅网络总线拓扑结构设计,路由跳数和节点能耗都逼近于理想水平,节能效果较好,延长了网络寿命。
In order to improve the life cycle of fiber grating network, bus topology optimization and energy saving design. Aiming at the problem of energy fading and network receiving failure easily caused by maximum angle routing algorithm for network local energy balance control, an energy saving design method of optical fiber grating network bus topology based on minimum hop count routing algorithm is proposed. The link energy balance constrained control method is used to design the topology of the network bus. According to the robustness of the network topology, the whole network is designed with energy balance. The energy balance of the network and the communication load of the node are considered. Optimize the bus topology with the cost of minimizing the energy consumed in the network link. The simulation results show that the proposed method can be used to design the topology of the FBG network bus. The routing hops and node energy consumption are close to the ideal level, and the energy-saving effect is better and the network lifetime is prolonged.
