A Regularity-Based Connectivity Analysis of Three-Dimensional Wireless Sensor Networks

The connectivity is one of the key issues in the design and application of wireless sensor networks, which is a basic guarantee for the normal operations of networks. In this paper, the region regularity is introduced into the wireless sensor network model for connectivity analysis. By analyzing and simulating the link probability, the average node degree and the node density of networks, we summarize the influence of region regularities on network connectivity. Experimental results show that the connectivity varies with different region regularities and reduces with the decrease of region regularity. Moreover, the energy efficiency and lifetime of the sensor networks can be improved by the analysis of region regularity. To the networks in two-dimensional plane, the proposed methods can also be applied.
