Load-Balancing Dynamic Source Routing For Automatic Meter Reading

This paper describes the characteristics of typical powerline carriers and micro-power wireless communication in local AMR system. In order to solve the problem of low acquisition success rate, this paper presents a dual-channel self-organizing network model in local AMR system, based on powerline channel and micro-power wireless channel. In a self-organizing AMR network, relay routing selection is a crucial challenge in cooperative communication. Thus, a load-balancing dynamic source routing (LDSR) algorithm was designed, which is based on the activity of the meter node, and which uses the relaying number in each node and its neighbor nodes to indirectly evaluate the activity of each node. If some node's activity exceeds a certain threshold value, the cost of the node to relay packet is increased. Compared to the pure DSR algorithm, the LDSR algorithm effectively reduces the maximum number of relay packets among all nodes. This can shorten the meter reading period and increase network throughput. The superiority of this proposed routing scheme was verified through a simulation.
