Load balancing techniques for extending smart metering system lifetime

In smart metering systems, when the density of node is high or distance of communication range is large, the adjacent node number becomes large. If routing based on the number of hop from the sink node is used in such a network, the deviation of load will become large and it will shorten the network lifetime, also degrades other network performance. In this paper, we proposed the techniques solving the above-mentioned problem as routing technique and intermittent interval control technique. The sender node control reduces differences in load and throughput resulting from topology by bypassing to sideward nodes. In the receiver node control, data reception probability is controlled by adjusting the intermittent interval. Simulation results show that proposal technique prolonged the network lifetime by about 53%, and reduced the average delay time by about 21%, comparing with existing method.
