Multi-Hop Transmission Algorithm Based on Connectivity in Wireless Sensors Networks

According to the wireless sensor network composed of sensors with various different functions,a multi-hop transmission routing algorithm(MHTA)based on connectivity is proposed.In this algorithm,according to node energy distribution's difference,the weighting factor is introduced as adjustment parameter for the cluster-head's election.In the process of election,combines multiple factors such as each node's energy consumption,its adjacent degree to base station and its number of neighbor node to select the cluster heads.In order to reduce the energy consumption in the data transmission process,the Intra-Cluster and Inter-Cluster multi-hop transmission algorithm is proposed.Simulation results showed: This algorithm can reduce cluster-head's energy consumption,balance the network load,and prolong the network's lifetime.
