Corona Sensor Cell based Deployment for Multiple-Sink Wireless Sensor Networks
Authors: , , ,
Abstract: Wireless sensor network (WSN) scalability and energy-efficiency issues remain an interesting research problem. This paper presents a multiple-sink deployment scheme for large-scale WSNs. An 8-rings Corona style sensor network is regarded as a Corona Sensor Cell (CSC) based on coarse-grain location awareness for energy-efficiency consideration. The overall task includes nodes training and data delivery. Let a specific WSN consists of N CSCs. In training protocol periodic, the costing ratio for the traditional single-sink scheme compares with our proposed multi-sink scheme is approximately0.7 N . In data delivery period, the sensor node power consumption ratio for the traditional single-sink scheme compares with our proposed multisink scheme is approximately 0.9 N . Thus, the proposed scheme is more energy efficiency than the traditional scheme.
