针对由各种功能不同的传感器构成的无线传感器网络,提出了一种基于连通度的多跳传输的路由协议(MHTA),该算法根据网络中节点能量分布的不同,引入权重因子作为调节参数进行簇头选举,选举过程中综合考虑了各节点消耗能量,与基站的邻近程度和周围邻节点的数目.为了减少在数据传输过程中消耗的能量,提出了一种簇内多跳和簇间多跳相结合进行数据传输的方法.模拟实验结果证明:该算法能够降低簇头能量消耗,均衡网络负载,从而延长网络生存时间.
Aiming at the wireless sensor network which consists of sensors with different functions, a multi-hop routing protocol (MHTA) based on connectivity is proposed. According to the energy distribution of nodes in the network, a weighting factor is introduced as an adjustment parameter Cluster head election, the election process takes into account the energy consumption of each node, the proximity of the base station and the number of neighboring nodes.In order to reduce the energy consumed in the data transmission process, a multi-hop intra-cluster and multi-cluster Jump combined with the method of data transmission.The simulation results show that the algorithm can reduce the energy consumption of cluster head, balance the network load, thereby extending the network lifetime.
