Fault-tolerant and energy-efficient routing protocols for a virtual three-dimensional wireless sensor network

摘要

In this paper, we consider a low-density, three-dimensional Wireless Sensor Network (3D WSN for short) in which the distribution of the sensors is poor, and the 3D virtual architecture proposed in our previous work. This later architecture provides a powerful, fast and economic partitioning of the network into a set of easily manageable clusters. We derive a fault-tolerant and energy-efficient routing protocol that allows efficient broadcasts of the data collected by the sensor nodes to a base station- a sink node located at the center of the network. Unlike existing routing protocols that run only on dense Networks ours is reliable on any type of 3D WSN: dense, sparse or non-connected. It can lead to the development of efficient algorithms for many applications as multicast, geocast, data aggregation, data collection with authentication and security. (C) 2018 Elsevier Ltd.
