Incremental Network Programming for Wireless Sensors

Free registration required

Executive Summary

The authors present an incremental network programming mechanism which reprograms wireless sensors quickly by transmitting the incremental changes using the Rsync algorithm; they generate the difference of the two program images allowing one to distribute only the key changes. Unlike previous approaches, their design does not assume any prior knowledge of the program code structure and can be applied to any hardware platform. To meet the resource constraints of wireless sensors, they tuned the Rsync algorithm which was originally made for updating binary files among powerful host machines.
