Abstract:

Clustering is an important energy-saving mechanism in sensor networks. Most existing clustering algorithms ignore the reverse-data-forwarding phenomenon suffering from limitations in energy efficiency. A directional clustering algorithm (DCA) is proposed for data aggregation in sensor networks. DCA ensures that node’s data is always transmitted towards to sink but not away from it during the whole forwarding route, so as to avoid energy waste caused by the reverse-data-forwarding phenomenon. Simulations show that DCA possesses higher energy efficiency and can prolong the lifetime of sensor networks.

Key words: reverse data forwarding, directional clustering, data aggregation, energy consumption
