Abstract: With the thriving of the Internet of things, the applications of wireless sensor networks (WSN) become more and more extensive. As the core technology of the network layer, the routing algorithm has become a hot issue for wireless sensor networks. Taking the limited energy of sensor node into account, this paper proposes a novel routing algorithm. Firstly, this paper devises a biological cell clustering method based on similarity between biological cell selection and distributed systems. In order to minimize the energy consumption and maximize the network lifetime, this paper proposes an optimal distance routing algorithm. With the combination of the devised clustering method and the proposed routing algorithm, all nodes are divided into clusters, and intra-cluster routing and inter-cluster routing are accomplished to transfer data. The proposed algorithm has been implemented by simulation, and the performance evaluation has been done over different network topologies. Simulation results show that the proposed algorithm can reduce the network energy consumption and extend the network lifetime effectively with better performance than existent routing algorithms.
