A Kind of Adaptive Energy Management Protocol for Wireless Sensor Network

Abstract

A new modeling assumption for wireless sensor networks was put forward. Under the modeling assumptions, a new energy conservation scheme was designed and implemented for efficient data, propagation. The network conditions were locally monitored, and accordingly the sleep-awake schedules of the nodes was adjusted to improve operation choices. The protocol was tested in software. Using the network simulator ns-2, the adaptive energy management protocol (AEMP) was compared with the Directed Diffusion Protocol (DDP) and the achieved performance was evaluate with a detailed simulation study. The advantages of our protocol are that it do not require knowledge of topology and not requires explicit coordination of sleep-awake schedules between nodes. Simulation results show that this new scheme is simple, and Directed Diffusion with AEMP outperforms again the stand-alone Directed Diffusion.
