A Design of Lightweight Reprogramming for Wireless Sensor Networks
ABSTRACT Considering a maintenance of sensor networks, wireless reprogramming techniques are required. Particularly, when sensor networks
are introduced to targeted environment, several parameters of sensor nodes must be calibrated, for example, sensing interval,
data sending interval. To change these parameters, we don’t have to reprogram the whole of program. It is needed to update
only program sections that include targeted variables in our sensor network. We designed and implemented a lightweight reprogramming
scheme. This scheme doesn’t require reboot of sensor nodes, therefore we don’t have to stop the services in long term. Our
proposal makes reprogramming efficient in respect of service availability and energy consumption.
