Energy Balance Quorum System for Wireless Sensor Networks

Abstract

In recent years, wireless sensor networks (WSNs) technology has been widely used in various fields because of its advantage of low construction cost. Based on the characteristics of sensor-limited power, there are presently many studies that explore how to extend the life cycle of WSNs under limited power conditions. Some research designed sensor wake-up scheduling mechanisms according to the quorum system that can not only achieve the effect of energy-saving, but also ensure the rendezvousing opportunities between the sensors. However, there is a problem of rendezvous idle when the sensor performs a sensing task. In order to improve the power-saving efficiency of the sensors, this paper designs an energy balance quorum system(EBQS). In addition to ensuring the opportunity to rendezvous between the sensors, this system can also balance the remaining capacity of the sensors and improve the power-saving efficiency of the traditional Quorum System depending on the remaining capacity of the sensors and the way they rendezvous. The experimental results show that the EBQS proposed in this paper can effectively reduce the number of slots compared to the traditional quorum system scheduling mechanism.
