Abstract

In this paper, we investigate the fault tolerance of connectivity probability for CDMA-based wireless sensor networks with variations of nodes deployment. The variations of deployment are modeled 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. We evaluate the connectivity performance with SIR 0,3-con, the minimum requirement of SIR, SIR0 for the 3-connectivity, when the nodes suffer a failure rate Pf. Simulation results show that the hexagonal and grid topologies suffer a degradation of -2.4 and -0.5 dB, respectively, when the failure rate Pf equals 0.1. However, the triangular topology shows robust fault tolerance with the failure rate Pf below 0.5 and moderate variations of deployment.
