Software Update Recovery for Wireless Sensor Networks

Free registration required

Executive Summary

Updating software over the network is important for Wireless Sensor Networks in support of scale, remote deployment, feature upgrades, and fixes. The risk of a fault in the updated code causing system failure is a serious problem. In this paper, the authors identify a single, critical, symptom loss-of-control that complements exception-based schemes, and supports failsafe recovery from faults in software updates. They present a new software update recovery mechanism that uses loss-of control to provide high-reliability, low energy, software updates, including a comparison of optimised-flooding against spanning-tree for determining loss-of-control in a multi-path environment.
