Research on Clustering Based Routing Energy-Saving Technology for Wireless Sensor Network

The clustering routing protocol for wireless sensor network (WSN) is the main part of this study. The number of sensor nodes in WSN is numerous and single node is extraordinarily limited in resource. The most significant aim of designing routing protocol of WSN is to reduce the overall energy dissipated in the network and to maximize the network lifetime. After taking into account the transmission and circuit energy together, the appropriate application scenarios of both multiple input multiple output (MIMO) and single input single output (SISO) are derived, and then a collaborative MIMO strategy based on clustering is proposed. Taking the merits of both transmission modes, the strategy reaches an optimal result in respect of energy consumption. Meanwhile, the algorithm distributes the energy consumption of cluster head to collaborative nodes, thus even balance the load and prolong the network lifetime.
