-The dissertation is organized as follows: the next chapter presents a scientific background about wireless sensor networks. Chapter 2 states a review of the related literatures to the coverage problem in WSN, the prior works, and the current works. The evaluation tools and optimization solvers have been investigated in Chapter 3. Chapter 4 describes the the proposed DiLCO protocol. Chapter 5 presents the MuDiLCO protocol. The PeCO protocol is illustrated in Chapter 6. Finally, we conclude our work in Chapter 7.
