Abstract

Sensor networks(SN) feature low-cost sensor devices with limited wireless network capacity, transmit power and energy. This paper proposes a new routing model (Tiny Reg) based on regular-graph theory and a clustering method. By dynamically arraying cluster heads into a hierarchy transmission tree in sensor networks, our two-level approach shortens the transmission distance between cluster heads and the sink. This reduces the energy consumption during packet delivery. Simulation results show the improved energy-efficiency performance of our method compared with existing protocols.
