Self-organizing redundancy-cellular architecture for wireless sensor networks
Xiaofei Wang, Thomas Berger · 2005
We propose self-organizing redundancy-cellular architecture (SoRCA) - a cell-based architecture for wireless sensor networks (WSN). SoRCA conserves energy by significantly reducing redundant data admitted to the network. It is scalable, robust and guarantees coverage. At a cost of extra energy, it can supply adjustable resolution. SoRCA also significantly simplifies the network models and may serve as a framework for mathematical analysis and simulation of WSNs. A formula for network lifetime is derived for location-based SoRCA and is verified by simulations. In addition, a scheme for extending network lifetime is proposed. We also evaluate various partitions from practical perspectives and show that hexagonal partitions are best for the class of cell-based WSNs.
