Review Paper on Data Gathering Techniques Based on Mobile Sink in WSN

Abstract: The main problem with fixed sink WSN network is energy hole creation near to the fixed sink node. This problem’s resolution is explored by distributing the energy consumption in many wireless sensors by using the mobile sink node concept. The mobile sink method of data gathering is much more efficient as compared to static sink design due to which it has attracted so much of attention in recent times. However, the path which the mobile sink follow while moving in the network area is the topic of extensive research. The optimization of the moving trajectory of mobile sink plays a vital role in making a WSN’s design energy efficient.
