A secret handshake scheme for mobile-hierarchy architecture based underground emergency response system

Wireless Sensor Networks (WSNs) is one of the most important solutions for emergency applications, such as fire, flood and volcano monitoring, especially underground disasters. In this paper, we propose a mobile-hierarchy WSN architecture for underground emergency response system and a secure handshake scheme for the mobile-hierarchy architecture. In the discussions, the proposed secret attribute handshake scheme verifies the legitimacy of a node over an insecure wireless communication channel and accomplish the secret attributes negotiation. Mobile-hierarchy WSN architecture is evaluated in underground emergency response system by experiments. It shows good efficiency by extensive simulations in special emergency scenario. Moreover, it enables a new efficient solution to underground emergency response system.
