A Comparative Analysis of Various Mobile Sink Routing Protocols and Performance Comparison of Clustered Routing Protocols in Mobile Sink Scenario

The concentration of data transfer towards the sink in a wireless sensor network causes the nearby nodes to exhaust their batteries faster than other nodes, which leaves the sink trapped and disrupts the data reporting by sensor nodes to each other. To avoid such scenarios, protocols with mobile sinks was proposed. It helped in achieving load balancing and uniform energy consumption throughout the network. We tried to concentrate on the dynamic requirements of mobile sink. We have provided an overview of the concerns of a mobile sink routing protocol, design requirements and challenges associated with the problem of mobile sink routing. Along with it, we explained the types of mobile sink protocols and compared them on the basis of some important parameters that define a protocol. In this paper, the concept of mobile sink is proposed with various protocols that were defined with static sink. Mobile sink is supposed to be moving in each round and data collection is done through Coordinator cluster head (CCH) which collects the data through various cluster heads (CH). Simulation result showed that mobile sink concept is increasing the network lifetime.
