Abstract: It is studied, in this paper, the cluster-based network architecture combined with multi-hop transformation and a hop-number-constrained multi-hop routing (HMR) algorithm is proposed. This new scheme is designed to prolong the network lifetime in which the maximum hop-number is considered in order to enhance the stability of the communication from sensor nodes to base station. Meanwhile, nodes with higher residual energy undertake more tasks of relaying information so as to balance the energy consumption in the network. Simulation results show that this new scheme provides longer lifetime than the classical clustering algorithms, and HMR also reaches larger amount of effective messages.
