A color-based energy-efficient topology control algorithm was presented , called CEETC, to minimize the energy loss in dense WSN .The algorithm classified and colored dense nodes , and the nodes of the same color can transmit data .Only if there are no nodes of the same color in the effective transmission distance , the nearest neighbor node of the other color and most remaining energy can be chosen to transmit data .It can reduce the number of neighbor nodes effectively , and transit transfer data to a base station after fewer hops .It can avoid the routing transmission with the multiple neighbors used in the traditional dense wireless sensor network topology control algorithms , thereby saving the energy consume in data transmission , and delaying the survival of the network .Simulation results show that CEETC can pass data to the base station node quickly with less energy , and thus getting higher energy consumption rate and prolong the lifetime of WSN , compared with other typical routing algorithms .%针对一类稠密无线传感网,提出了一种基于着色能量高效的网络拓扑控制算法CEETC.该算法将稠密结点进行合理着色分类,同色的结点能够传输数据,只有在有效传输距离内没有同色结点时可选择距离最近且剩余能量多的其他着色邻居结点进行数据传输,能够有效地减少结点邻居数目,经过较少的路由跳中转将数据传输给基站,避免结点稠密无线传感网拓扑控制算法采用多邻居路由传输,从而节约了数据传输过程中因数据转发而带来的额外能量消耗,延长了网络的存活率.仿真结果表明,与其他典型的路由算法相比,CEETC能够更快地将结点数据传递给基站且结点消耗比较少的能量,获得更高的能量消耗率和更长的网络生存期.
