Abstract
In this paper, we propose a transmission scheme to reduce energy consumption on wireless multi-channel sensor networks. This proposed scheme differentiates the number of usable channels based on a priority. Sensor nodes consume the most energy to transmit data. Also, as transmission distance is far, they consume the more energy. Therefore retransmission due to transmission failure of sensor nodes that are long transmission distance is required more energy consumption. In this paper, we provide a stable transmission environment by allocating a high priority for data that is sent far away. The received data with a high priority is more allocated the number of usable channels. In the experiment results, the receiving failure probability and the restransmission energy consumption of proposed scheme is superior to ones of comparison scheme.
