A Survey on Various Routing Technique for Wireless Sensor Network with Sink and Node Mobility

node mobility,mobile sink,energy efficiency

Wireless sensor network contains a huge number of sensor nodes for communication. Some nodes can work as a gateway which transmits data to the sink. These nodes are considered as a bottleneck in multi-hop networks because they transmit data collected from other nodes and hence it drains their energy quickly. This problem is known as Hotspot problem. So, for balancing the energy throughout the network, sink and node mobility can be used. A mobile sink which could collect data without the need of gateway, and hence the problem of a bottleneck in the multi-hop network can be minimized. Along with the sink, sensor nodes also can be made mobile. Energy efficiency of WSN is achieved by using mobile sensors and mobile sink with improved coverage, enhanced target tracking, and superior channel capacity. There are various routing protocols to minimize energy consumption in a mobile wireless sensor network. This paper mainly focuses on the study of different protocols that are used for efficient energy consumption using the mobile sink and mobile sensor nodes.
