A comparative analysis of various 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 nearby nodes exhaust their batteries faster than further nodes, this leaves the sink trapped and disrupts the data reporting communication between sensor nodes. To avoid such scenarios, protocols with mobile sinks were proposed. They helped in achieving load balancing and uniform energy consumption throughout the network. This research aimed to concentrate on the dynamic requirements of the mobile sink by providing an overview of mobile sink protocol concerns, design requirements, and challenges associated with issues of the mobile sink routing. On the other hand, in this research different types of mobile sink protocols are reviewed and compared on the basis of some parameters of the sink protocol. In this paper, the concept of the mobile sink with various protocols that were defined with the static sink is presented. Mobile sink is supposed to be moving in each round and the data collection is done through Coordinator Cluster Head which collects the data through various cluster heads. Simulation results showed that mobile sink concept is increasing the network lifetime.
