A Tree Based DATA Transportation Scheme for wireless sensor networks

Approaches to transmit the collected data from cluster heads to the Sink, a novel inter-cluster data transportation scheme for wireless sensor networks-TBDTS (A Tree Based Data Transportation Scheme) is proposed. Considering the node's energy and location, TBDTS defines a weight value, and constructs an energy-efficient weight-based spanning tree passing through all cluster-heads. Moreover, this algorithm introduces a transmission range, and makes isolated nodes to connect to the network, by directly communicating with the Sink. Comparing with the existing algorithms, the simulation results show that TBDTS can decrease more transmission energy cost and achieve better transmission reliability.
