Managing Data Transmission To Improve Lifetime of Wireless Sensor Network

Wireless sensor network (WSN) is a set of small sensor nodes with a limited amount of energy that is randomly deployed in an area of interest to transmit massive data. One of the main objectives of designing wireless sensor network is to make data transmission effective to increase network longevity and avoid premature death of nodes through energy management methods. In this paper, an energy-efficient routing scheme for WSN is proposed based on fuzzy logic for selecting a cluster head (CH), Node remaining energy and a distance of the Node to the base station (BS). The distance to the cluster head is taken into account as the inputs to be fed into the fuzzy inference system to determine the cluster heads. We also suggested an approach to managing the data transmission in a wireless sensor network to decrease the overall energy consumed; thus, extending the network lifetime. The performance of the proposed approach is evaluated using MATLAB simulation tool and compared with the LEACH protocol. Simulation results illustrated that the proposed protocol works better than LEACH regarding energy consumption and extending the network lifetime.
