A Multi-hop Data Gathering Method for Wireless Sensor Networks

Abstract

In wireless sensor networks used in environmental monitoring, data collection, the data generated by the sensor nodes will be transmitted with many hops from the sources to the destinations. In order to transmit the important data quickly, as well as reduce the energy consumption and extend the lifetime of networks, a multi-hop data gathering method (MHDG) for wireless sensor networks is proposed. The method aggregated the data from sensor nodes and marked the priority for the data with the source nodes. Simulation results show that compared to existing traditional method, the proposed method achieves the goal of a longer life time of networks, a lower packet drop ratio and energy consumption.
