Automatic routing mechanism for data aggregation in wireless sensor networks

To act an appropriate response for intelligent system, it is necessary to obtain sufficient information as possible. Wireless sensor networks technology is one of possible solutions that can provide intelligent system with sensing information of specific task. However, a large number of data transmissions for a long period of time might cause sensor node to lose its functionality. This is because sensor nodes have the restriction of energy, computing capability, and communication bandwidth. Therefore, data aggregation mechanism is one of possible solutions to prolong the life time of sensor nodes. In this paper, we present an automatic routing scheme for data aggregation using geographic information. Clustering the entire interesting field and chaining interesting nodes with "virtual link" of which "virtual path" is composed are proposed. The simulation results show that the proposed method can effective save transmission energy and bandwidth utilization.
