The structure of many possible applications of wireless sensor networks with energy harvesting functions can be one dimensional. For this environment, this paper introduces a relay node that forwards data of a number of neighboring sensor nodes to data sink so as to increase the data gathering frequency while maintaining all sensor nodes alive. We also propose an algorithm that determines the relay node, the per-node based forwarding strategies, the sleep duration after next round, based on the values of remaining energy, harvesting power, and the estimated communication energy of every sensor nodes. Numerical analysis based on communication energy model and practical assumptions shows that the proposed algorithm has at most 10 times larger value of data gathering frequency compared to single hop and multi-hop forwarding only strategies.
