Dynamic Transmission Target Selection Scheme for Load-Balancing in WSN

We studied a dynamic transmission target selection scheme for load-balancing in WSN. The goal is for the energy consumption of packet transmission for all nodes to be nearly same as possible. For a load-balancing, it should be needed to predict the scale of the transmission energy of all nodes. In multihop transmission mode, a fixed transmission path is necessary for the load-balancing of nodes that are at the same hop distance from the sink node (we call as horizontal hopping transmission), and a variable range transmission mode is needed for the load-balancing of nodes that are at different hop distances from the sink node(we call as vertical hopping transmission). In this paper, we developed a dynamic transmission target selection scheme for horizontal-hopping and vertical-hopping transmission. The performance evaluation results show that the energy consumption of all the nodes was nearly the same, and the performance achieved was superior to that of existing load-balancing schemes.
