Survey on techniques for cluster based communications in WSN.

Abstract

Wireless Sensor Networks basically depends upon the data gathering scheme. In WSN when compared to mobile data gathering time, data uploading takes large amount of time. The time taken for data uploading can be decreased by placing multiple antennas on the mobile collector. Hence for data gathering a three-layer framework has been proposed, which contains Sensor, cluster-head and the mobile collector layer also named as SenCar layer. This three layer framework proposed employs an algorithm called as distributed load balanced clustering and dual data uploading, also termed as LBC-DDU. The aim lies in increasing the network lifetime, low latency for data gathering and good scalability. When compared to the existing schemes, the proposed scheme facilitates dual data uploading and balances the work load by introducing numerous cluster head simultaneously in every cluster. Through inter cluster transmissions, SenCar receives information from the cluster head and in turn SenCar transmits the information to sink node.
