基于控制簇头能量的改进分簇路由算法

Improved clustering routing algorithm based on energy control of cluster-heads

针对LEACH协议中簇头节点能量消耗相对过快,导致部分节点加快死亡、网络能量利用率降低的缺陷,提出一种改进的方法。通过计算理想簇半径,限制簇头的发射功率,从而减少簇头能量的消耗。仿真结果表明,改进后的方法能均衡节点的能耗,有效地延长了整个网络的生存期。

Aiming at the problem about LEACH algorithm that the energy consumption of cluster-heads is relatively fast,resuiting in speeding up some nodes to death and reducing the utilization of network energy, it proposes an improved method. This method restricts the transmission power of the cluster-heads by calculating the ideal cluster radius, thus to reduce energy consumption of the cluster-heads.The results of simulation show that the improved method can balance energy consumption of nodes and prolong the lifetime of the whole networks;
