Code Propagation in Wireless Sensor Networks
Wireless sensor networks consist of many radio-equipped nodes which are limited in resources and power. After deployment, these nodes may need reprogramming to fix bugs, add features or make the nodes suitable for another task, among others. Because it may be impractical to physically visit these nodes to reprogram them, several methods have been proposed to reprogram nodes using data sent over the network. This paper gives an overview of methods to propagate code through the network and to reduce the size of this code.
