Fuzzy Logic based snooze schema for wireless sensor network MAC protocol

摘要

Energy competence is an imperative aspect to intend an extensive existence wireless sensor network. Several methods have been proposed to increase the battery lifetime of sensor nodes. One of the methods is sporadically turn off the radio receivers of the sensor nodes in a synchronized mode. The sleep and wake up mode are included with this corresponding nature. Arbitrarily elected node form virtual clusters based on universal snooze scheme. However, protocols resembling the extensively known S-MAC possibly will require some nodes to pursue several snooze schemes causing them to wake up more frequently than the other nodes. In this paper we present the wireless sensor networks by means of S-MACF (for S-MAC Fuzzy) where a significant amount of the nodes may have to stay awake much extended than expected. An adjustment of the protocol is then projected to get rid of the requirement for the nodes to keep on awake longer than the other nodes. The customized edition improves the energy efficiency and enhances the life length of a wireless sensor network (WSN).
