An Integrated Protocol for Maintaining Connectivity and Coverage Under Probabilistic Models for Wireless Sensor Networks

Free registration required

Executive Summary

The authors propose a distributed connectivity maintenance protocol that explicitly accounts for the probabilistic nature of wireless communication links. The proposed protocol is simple to implement and it achieves a given target communication quality between nodes, which is quantified by the minimum packet delivery rate between any pair of nodes in the network. They demonstrate the robustness of the proposed protocol against random node failures, inaccuracy of node locations, and imperfect time synchronization of nodes using extensive simulations.
