Abstract
Wireless Sensor Network is a group of specialized sensors have the ability to sense, monitor, communicate to the neighbors and recording conditions at assorted locations such as temperature, sound, pressure, security purpose etc. The sensed data's incurred for estimation and then forwarded to the neighbors. There are many challenging issues in WSN such as localization, synchronization, data aggregation, dissemination, database querying, architecture, middleware, security, power consuming, routing, abstractions and higher level algorithms. Maximizing the lifetime of energy dearth Wireless Sensor Networks is a very big challenging issue in the present context. An optimized solution is needed to increase the lifetime of the Wireless Sensor Networks. In this paper the depiction of mobile sinks with a choice of routing protocols is used in different scenarios to enhance the efficiency and life time of WSN.
