Nearest neighbor nodes and connectivity of three-dimensional wireless sensor networks with Poisson point field

Some problems about the connectivity of wireless sensor networks (WSNs) are always important and difficult topics in research, especially the trade-off between connectivity and energy control. In this paper, we present a novel and effective method to calculate nearest neighbor nodes in three-dimensional WSNs using Poisson point field theory, which enables each node to find the kth nearest neighbor node and adjust transmitting range according to local requirement. Simultaneously, the probability expression of the k-connected network is given.
