“…Thus, the associated energy consumption and lifetime of the WSN can be analyzed and optimized before the deployment. Wu et al [ 8 ], Liu et al [ 21 ] and Wang [ 22 ] divide the target area into multiple rings and analyze the optimal sensor deployment schemes in different rings. AbdelSalam [ 23 ], Chiang et al [ 24 ], Fan et al [ 25 ] and Gupta et al [ 26 ] study the structured deployment methods based on grids, and Onur et al [ 16 ] deployed a WSN based on grids to monitor Dolmabahçe Palace in Istanbul.…”

Sensor-deployment-based lifetime optimization is one of the most effective methods used to prolong the lifetime of Wireless Sensor Network (WSN) by reducing the distance-sensitive energy consumption. In this paper, data retransmission, a major consumption factor that is usually neglected in the previous work, is considered. For a homogeneous WSN, monitoring a circular target area with a centered base station, a sensor deployment model based on regular hexagonal grids is analyzed. To maximize the WSN lifetime, optimization models for both uniform and non-uniform deployment schemes are proposed by constraining on coverage, connectivity and success transmission rate. Based on the data transmission analysis in a data gathering cycle, the WSN lifetime in the model can be obtained through quantifying the energy consumption at each sensor location. The results of case studies show that it is meaningful to consider data retransmission in the lifetime optimization. In particular, our investigations indicate that, with the same lifetime requirement, the number of sensors needed in a non-uniform topology is much less than that in a uniform one. Finally, compared with a random scheme, simulation results further verify the advantage of our deployment model.
