SURVEY ON ENERGY EFFICIENT AND LOAD BALANCED DATA COLLECTION ALGORITHMS IN WIRELESS SENSOR NETWORKS

The extensive development of wireless sensor networks lead to deployment of numerous real world applications. The sensors which is in mobility is used to sense physical or environmental conditions and store the data to be collected by the base station of the sink. The efficacy of wireless sensor network relies on the data collection stratagem. In the study of many dat a collection algorithms for WSN, the algorithm fails to provide the consistency of the network in respect of coverage distance, delay, traffic, load balance, energy efficiency and end - to - end connection. To support high scalability and better data aggregati on, sensor nodes are often grouped into disjoint, non - overlapping subsets called clusters. Clusters create hierarchical WSN, which incorporate efficient utilization of unlimited of sensor nodes and this extends network lifetime. This paper compares various data collection topologies in terms of providing better Quality of service
