Poster Abstract: Storage-Centric Debugging of Performance Problems in Sensor Networks
After almost ten years of research into sensor networks, deployments continue to fail. Such failures are due to the distributed nature of sensor networks and the complex interactions of protocols. A variety of debugging tools have been developed to determine the exact causes of failures, and to mitigate the poor visibility into the operation of many sensor network protocols. Performance debugging of sensor networks has been limited to testbed experiments in the pre-deployment phase, where the developer typically has access to a separate wired channel for unintrusive debugging. Since it is difficult to mimic the environment of a deployed network in a testbed, debugging tools for deployed networks are desirable.
