摘要
针对无线传感器网络受Wi-Fi等异构系统干扰日益严重的问题,在引入基于簇的动态多信道组网策略的基础上,综合考虑频谱受干扰程度、信道切换代价、节点剩余能量等因素,提出了一种认知频谱干扰的能量有效的路由(CSIEE)算法。仿真结果表明,该路由与EEPA,AODV,AODV-EA路由相比,有效地节约了传感器节点能量,延长了网络生命周期。
Wireless sensor network disturbed by heterogeneous system becomes increasingly serious, and in order to solve this problem, this paper presents a spectrum of cognitive interference energy efficient （CSIEE） routing algorithm considering the cost of channel switching, spectrum interference degree, node residual energy and other factors. Simulation results show that compared with routings of EEPA, AODV and AODV-EA, this algorithm can reduce the energy consumption and prolong the life cycle of the network.
