Abstract:

Code dissemination is an important building block of wireless reprogramming. We notice that current code dissemination protocols fails to consider page selection and energy balancing. In this paper, we present an integrated mutual selection based code dissemination protocol (MSD). The key idea of MSD is mutual selection comprising sender selection and page selection. By exploiting link quality information in mutual selection, MSD enhances the propagation. Further, MSD takes energy level information in the sender selection, thus avoiding low power nodes’ over-consumption. We simulate MSD by settings of Mica-Z motes. Simulation results show that MSD can reduce the completion time and average transmission, and help low power nodes avoid unnecessary transmission and energy consumption.
