Data Dissemination in Wireless Sensor Networks with Clustering Method

Chao Gao, Xiaoya Hu, Bingwen Wang, Hongliang Gao and Wei Xiong

In Wireless Sensor Networks (WSNs), since the network consists of low-cost sensor nodes with finite battery power, energy efficient is the primary consideration in algorithm design in order to prolong the network lifetime. Various schemes had been proposed to efficiently store and process sensed data. In this study, a data storage scheme called Cluster Based Data Storage (CBDS) is proposed to reduce the communication cost for transmitting data and to efficiently process data queries. The CBDS uses the clustering architecture to efficiently transmit and store data. To our knowledge, this is the first time using clustering method in data centric storage. The CBDS uses the virtual coordinate instead of geographic location information. So CBDS does not need to use the GPS or other technologies to locate, it also saves energy. Moreover, CBDS does well in handling hot spot problem. Analysis and simulation results show that the CBDS scheme outperforms the GTH-based DCS scheme.
