Expedite Privacy-Preserving Emergency Communication Scheme for VANETs

Abstract

The existing communication schemes are often unusable in natural disasters and public emergencies. But requirements of information collection and data transmission in emergency scenario are very imperative. Thus, sensor networks ad hoc networks are required in the emergency communication systems. For example, rescue vehicles equipped with wireless communication devices, sensors, and cameras are regularly used to collect and transmit the real-time information for the rescue action. The paper focuses on security solutions for the vehicular ad hoc networks (VANETs) in the emergency communication cases, in which the communication infrastructures are not always available. An expedite privacy-preserving emergency communication (EPEC) scheme is presented for the vehicles to securely connect with the others in the neighbor area even when the trusted infrastructures are destroyed by the disaster. EPEC satisfies conditional privacy preservation requirements, in which both lightweight signature and batch verification are employed to provide efficiency. We also show the proof of the security, feasibility, and efficiency of our EPEC by the theoretical and experimental analyses.

Energy-Efficient Transmissions for Remote Wireless Sensor Networks: An Integrated HAP/Satellite Architecture for Emergency Scenarios

“…Due to extreme conditions, high altitude platforms (HAPs) [ 3 ] and satellites [ 4 ] are vastly underused and can be utilized for various uses to construct a remote WSN. Integrated HAP/satellite (IHS) networks are expected to optimally meet the emergency communication requirements of emergency relief and recovery operations for tackling large-scale natural and man-made disasters [ 5 ]. IHS networks have a number of potential advantages over conventional technologies [ 6 ], including: High capacity regional coverage; Rapid deployment; Low power consumption; Potentially low cost.…”

Capacity Model and Constraints Analysis for Integrated Remote Wireless Sensor and Satellite Network in Emergency Scenarios

“…Hence, satellites are vastly underused and can be utilized for various uses to construct an integrated remote wireless sensor and satellite network in extreme conditions [ 7 , 8 ]. Integrated remote wireless sensor and satellite networks are expected to optimally meet the emergency information requirements of emergency relief and recovery operations for tackling large-scale disasters [ 9 ]. Due to the distinguishing characteristics of integrated remote wireless sensor and satellite networks, how to make these satellites and remote wireless sensors cooperate efficiently is challenging and important.…”
