slugFuzzy Base Enhanced LEACH IN WSN
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2014, Vol 2, Issue 6
Abstract
Wireless sensor networks (WSN) are highly distributed networks of autonomous small, lightweight sensors (nodes) in large numbers to monitor physical or environmental conditions by the measurement of, temperature, vibration, pressure, motion or pollutants, sound, and to cooperatively pass their data through the network to a main location (often called a sink). In designing WSN routing protocol, enhancing energy efficiency and extending the lifetime of WSNs are the most important challenges for researchers. In LEACH protocol each sensor nodes elects itself as a cluster head based on the probability model. Every sensor node will become cluster head in every cycle to evenly distribute the work loads. Main problem of LEACH protocol is it only depends on the probability model to elect the cluster head and therefore it is possible that no cluster heads or too many are selected in a single round. Moreover, selected cluster heads may be located near to each other or even near to the edge of the networks which leads to inefficient energy distribution. From the above discussion, we conclude that the focus of almost researches is to conserve energy at its maximum level. Our proposed model is also an improvement in the leach algorithm.
