Multi-base Station Placement for Reprogramming Wireless Sensor Networks

Reprogramming sensor nodes is an effective way to improve wireless sensor networks. The latest reprogramming protocols use radio communication to distribute software data. In large-scale sensor networks, several base stations are placed to disseminate software fast, but performances of reprogramming protocols for multi-base station environments have not been discussed. In this paper, we evaluate the features of software dissemination for multi-base station sensor networks. Simulations revealed that the placement and the number of base stations were the key parameters in software dissemination.
