Improving Efficiency of Wireless Sensor Network Using LEACH Protocols: Review Paper

In recent times, Wireless Sensor Networks (WSNs) have given promising directions for a mixed bag of application monitoring along withgathering the required data from the environment.Due to the insufficient transmission range and high density of nodes, routing is considered to be an important fieldof WSNs. The absolute lifecycle of a wireless sensor network robustly depends upon factors such like how the relaying neighbors are selected by the sensor and the data path taken to get to the objective. Energy used is more for transmission of data from the Cluster Headto the Base Station. Even supplementaryif the space between them is more. It is noticeable that by reducingdistance energy consumption mechanism will reduce the overall energy consumption of the entire network. Since these sensors are usually deployed in secluded areas where the charging or substitution of batteries is not possible, new methods should be planned to increase the network life span. In this paper we have taken our concern towards it by presenting various protocols to improve the efficiency of the Wireless Sensor Networks, our main focus is to improve the battery life and the life time of the whole network. Furthermore this paper describes various improvements on LEACH protocols. It also enlists some limitations of LEACH and how the extended or modified versions of it have helped to overcome the problem.
