GCCT: A Graph-Based Coverage and Connectivity Technique for Enhanced Quality of Service in WSN

The area of wireless sensor network has been a constant source of attention in the research community owing to its potential remote sensing application as well as significant issues associated with almost every applications. Out of various types of issues, coverage and connectivity is one of the unsolved issues till date in wireless sensor network that potentially degrade the efficient performance capability of the applications in wireless sensor network. This paper introduces a graph based coverage and connectivity technique (GCCT) that is aimed to attain better optimization of coverage and connectivity issues in large scale wireless sensor network considering the issues of energy depletion factor. A model is developed considering the radio and energy model of hierarchical routing protocol and a new module is introduced called as super-leader node, which aims to attain energy efficiency at a same time. Simulation results shows substantial energy conservation of GCCT compared to conventional protocols.
