Connectivity performance for CDMA-based wireless sensor networks with variations of deployment

In this paper, we investigate connectivity probability of ns of deployment are model by 2D Gaussian distribution with zero-mean for the triangle, grid and hexagon topologies. Thus, the k-connectivity performance is studied through the outage probability of CDMA signal links. Simulation results show that with a minimum requirements SIR0 = -10.7dB, the three topologies can perform 3-connectivity for small variation σN ≤ 0.07. Furthermore, with SIR0 = -12dB, 3-connectivity performance can be achieved with variation range by 0.08, 0.083 and 0.085 for the triangle, grid and hexagon topologies, respectively.
