Precise Packet Loss Pattern Generation by Intentional Interference

Download Now Free registration required

Executive Summary

Intermediate-quality links often cause vulnerable connectivity in wireless sensor networks, but packet losses caused by such volatile links are not easy to trace. In order to equip link layer protocol designers with a reliable test and debugging tool, the authors develop a reactive interferer to generate packet loss patterns precisely. By using intentional interference to emulate parameterized lossy links with very low intrusiveness, the tool facilitates both robustness evaluation of protocols and flaw detection in protocol implementation.
