A New Wireless Sensor Network Transmission Mechanism-Research and Simulation of RNTA Algorithm
一种新的无线传感器网络传输机制——RNTA算法的研究与仿真

To enhance the entire network lifetime of wireless sensor network, this paper puts forward a new transmission mechanism by redundant nodes basing on the characters that the sensor nodes are tiny and energy-limited. The method builds an redundant nodes tree as the transmission agents to realize the information exchange between the clusters and base-station so that the energy consumption of normal nodes and clusters’ heads can be decreased. The simulation results show that the mechanism can improve the lifetime of effective wireless sensor nodes largely under the condition that the nodes are relative dense and the redundant nodes exist.
