Finally we demonstrated that our results are robust to realistic sensing models and also validate the correctness through extensive simulations. The remainder of this paper is organized as follows the next section presents the optimized barrier coverage design Section 3 shows Mathematical modeling of Voronoi-based WSN based on energy consumption in detail Section 4 illustrates the proposed intelligent mobile target tracking scheme called CTT MAV Section 5 conducts experiments in Matlab simulator under multi-covered Voronoi-based clustered sensor network. Finally section 6 concludes the paper with future perspective. 2. Optimized barrier coverage design Although maintaining full sensing coverage guarantees immediate response to intrude targets sometimes it is not favorable due to its high energy consumption. We investigate a new and more efficient approach for deploying sensors in a large scale two dimensional monitoring area. New approach for sensor deployment To monitor an area WSN should achieve a certain level of detection performance. Due to the highly considerable cost in a given monitoring area better detection capacity and communication coverage is critical to sequential deployment of sensors. In this paper we explored a new approach for sensor deployment see Figure 2 to improve barrier coverage. Theorem 1. Let A denotes the area and f A denotes barrier coverage namely the fraction of the area that is in the sensing area of one or more sensors where sensors can provide a valid sensing measurement and r is the cartographic representation of area .Then 1 Ff p r a in G V E where E 0 Fig. 2.
