Energy-efficient based multi-path routing with static sink using fuzzy logic controller in wireless sensor networks

Abstract

In Wireless Sensor Networks (WSNs), routing protocols manage the communication between wireless sensor nodes. In a multi-path routing protocol (MRP), data can be transferred from source to sink node in a reliable manner based on Received Signal Strength Indication (RSSI) value of a sensor node. This paper improves the life time of WSN by applying Fuzzy Logic Controller (FLC) to construct multi-path routing protocol based on distance, node density and residual energy parameters of wireless sensor nodes. We show the efficacy of our proposed routing protocol by using simulations.
