Abstract:
Wireless sensor networks (WSNs) have recently achieved a great deal of attention due to its numerous attractive applications in many different fields. Sensors and WSNs possesses a number of special characteristics that make them very promising in many applications, but also put on them lots of constraints that make issues in sensor network particularly difficult. These issues may include topology control, routing, coverage, security, and data management. In this thesis, we focus our attention on the coverage problem. Firstly, we study the best current solutions in the literature. We choose one of them as the basis of our work and study it thoroughly as the core model of our coverage model. Then we describe how we tailor it to be suitable for uneven environments. Our proposed solution achieves full coverage with a noticeable low number of sensors. We present the simulation results and compare them with our core model to show the effectiveness of our proposed solution
