The authors describe an autonomous Emergency Support System (ESS) based on opportunistic communications (oppcomms) to support navigation and evacuation of civilians in built environments. In their proposed system, civilians are equipped with low-cost human wearable devices that employ oppcomms to exchange packets at close range of a few meters with limited or no infrastructure. This paper investigates the resilience and performance of oppcomms in the presence of network attacks. They assume that a portion of nodes in the network have been compromised and misbehave, which adversely affects communications and evacuation.
