PROJECT TITLE :

The Evolution of Sink Mobility Management in Wireless Sensor Networks: A Survey

ABSTRACT:

Sink mobility has long been recognized as an efficient method of improving system performance in wireless sensor networks (WSNs), e.g. relieving traffic burden from a particular set of nodes. Though tremendous research efforts are devoted to the present topic throughout the last decades, yet little attention has been purchased the analysis summarization and guidance. This paper aims to fill in the blank and presents an up-to-date survey on the sink mobility issue. Its main contribution is to review mobility management schemes from an evolutionary purpose of read. The connected schemes are divided into four categories: uncontrollable mobility (UMM), path-restricted mobility (PRM), location-restricted mobility (LRM) and unrestricted mobility (URM). Several representative solutions are described following the proposed taxonomy. To help readers comprehend the development flow within the category, the link among totally different solutions is outlined, with detailed descriptions furthermore in-depth analysis. In this manner, besides some potential extensions based mostly on current analysis, we tend to are able to identify several open issues that receive little attention or stay unexplored therefore way.
