An Effective and Efficient Method for Handling Transmission Failures in Sensor Networks
Abstract. The suppression scheme is a solution for limited energy constraints in sensor networks. Temporal suppression, spatial suppression and spatio-temporal suppression are proposed to reduce energy consumption by transmitting data only if a certain condition is violated. Among these suppression schemes, spatio-temporal suppression is the most energy efficient than others because it combines the advantages of temporal suppression and spatial suppression. A critical problem of these suppression schemes is the transmission failure because every nonreport is considered as a suppression. This causes the accuracy problem of query results. In this paper, we propose an effective and efficient method for handling transmission failures in the spatio-temporal suppression scheme. In order to detect transmission failures, we devise an energy efficient method using Bloom Filter. We also devise a novel method for recovering failed transmissions which can save energy consumption and recover failed...
