Delay-bounded and robust routing protocol for emergency applications using wireless sensor networks

Monitoring and response for emergency environments is a novel application area for the deployment of wireless sensor networks. In this context, delay-bounded delivery and robust routing is the essential operating criteria in order to ensure safe and timely response for emergency scenarios. Existing routing mechanisms for wireless sensor networks are not well suited for hazard situations, especially as they do not consider critical and dynamic network scenarios. In this paper, a novel delay-bounded and robust routing protocol is presented. The protocol adapts to handle dynamic emergency scenarios and works well with the routing “hole” problem. Theoretical analysis and simulation results indicate that our protocol is well suited for dynamic emergency scenarios when compared with other related work.
