SAHRC: A Cluster-based Routing Control Protocol for Wireless Sensor Network

Exploring a new routing control protocol is a hot spot in WSN research. A cluster-based Self-Adaptive Hybrid Routing Control (SAHRC) protocol for WSN in special application is proposed based on traditional LEACH protocol. It takes account of large-scale event-driven network application scenarios, uses self-configuring and trigger mechanism to solve the shortages of LEACH in large-scale networks, such as the lack of self-adaptability, leaving consideration of the nodes residual energy, and the difficulty in improving communication efficiency. The simulation experiments show that, compared with existing LEACH algorithm, the algorithm SAHRC provides higher performance in stability and energy-saving.
