Reliability Improvement of Multi-Path Routing for Wireless Sensor Networks and Its Application to Wormhole Attack Avoidance

Wireless sensor networks have recently been widely studied and applied in long-term mission-critical environments, where reliable delivery of sensing information under multiple node failure is required. In this study we discuss tabu-list-based multi-path routing which guarantees that multiple copies of events are delivered through completely different paths, without requiring additional communications to exchange path information. Toward development of attack-tolerant multi-path routing, we also investigate the effects of wormhole attacks and location-aware wormhole detection scheme.
