A Wireless sensor network is defined as a network of devices which are denoted as nodes, which can sense the environment and communicate the information gathered from the monitored field through wireless links [1].The data is forwarded, via multiple hops to a sink which uses it locally or is connected to other networks (e.g., the Internet) through a gateway [2-4].The wireless sensor networks have issues related to latency, speed, security and more energy usage.Recent research shows that latency minimization is a major problem in wireless sensor network [5][6][7][8][9].For this, different methods and algorithms are available in past research work.In wireless sensor networks, sink works like a gateway.There are different types of sinks like moving sink, static sink, single sink and multiple sink.As per past research, moving sink is better compared to other.One single mobile sink (WSN-MS) provides an effective method to collect data [10][11][12][13][14][15][16].In WSN-MS, all sensor nodes except mobile sink are stationary, and mobile sink can access sensor node's data by moving around them.
