An Experimental Study and Analysis of Impact on Mobile Sink in Wireless Sensor Networks

Targeting a growing number of promising applications sink mobility has been measured as a good strategy to prolong the lifetime of mobile wireless sensor network MWSNs. Mobile sink helps indirectly achieving uniform energy—consumption and provides load balancing to enhance data collection from the sensor node. Generally routing in MWSN is more complicated as it operates in low power, battery constraint with limited resources. A recent development in mobile sink leads to researcher to design routing algorithms for MWSN but still many unanswered gaps like shortest path, node mobility prediction, route reconstruction, and maintaining network coverage under movement and multi-sink approach for data collection towards critical events from sensor nodes. This paper address taxonomy of various data collection approaches under the routing protocol schemes sensor field. Based on this we classify routing schemes as location-based and query-driven approaches. Finally, discussion summarizes the detection of some unanswered issues and also gives a path to researchers to design and enhancement to improve existing routing schemes for future direction.
