Coverage and connectivity in Wireless Sensor Networks: Their trade-offs

In Wireless Sensor Networks deploying a sensor node ensuring full coverage with connectivity is a real challenge. It is extremely difficult to find an optimal node deployment strategy that can minimize cost, and communicate on overhead and provide a high degree of coverage with network connectivity. In this paper we have made a comparative study to reach an optimum deployment solution using a layered deployment model. We have also presented the trade-offs between optimal coverage and optimal connectivity topology and their mathematical foundations. The simulation results verify the mathematical calculations.
