摘要
提出了一种分布式能量有效的无线传感器网络分簇路由协议DEEC(Distributed Energy-efficient Clustering Routing)。该协议采用基于时间的簇首选择算法,广播时间取决于自身剩余能量和其邻居节点的剩余能量。在数据传输阶段,采用簇内单跳与簇间多跳相结合的方式,引入权值函数优化簇首中继节点的选择。仿真实验结果表明,与LEACH,PEGASIS协议相比,DEEC能够有效地节约单个节点能量、均衡网络能耗、延长网络生存周期。
A distributed energy-efficient clustering routing protocol(DEEC)for wireless sensor networks(WSNs)is proposed.DEEC uses time-based cluster head selection algorithm,and broadcasting time depends on the remaining energy of itself and neighbors '.In the phase of data transmission,DEEC adopts a combination of single-hop mode for intra-cluster communication and multi-hop mode for inter-cluster communication,and introduces a weight function to optimize the selection of cluster head relay.Simulation results demonstrate that DEEC outperforms LEACH(low-energy adaptive clustering hierarchy)and PEGASIS(power-efficient gathering in sensor information systems),and it can efficiently decrease the dead speed of the nodes,balance the energy dissipation of all nodes,and prolong the network lifetime.
