In a disaster or battlefield zone, rescue workers, soldiers, and other survivors (referred to as nodes) may need to survey damages and send images to the command and control center (the server) in a hop-by-hop fashion in the absence of any communication infrastructure. The server considers some area/landmark as the point of interest (POI) and distributes a request to the nodes to collect more information

A mobile sensing and visualization platform for environmental data Pervasive Mob. Comput. (IF 2.725) Pub Date : 2020-06-18 Armir Bujari, Ombretta Gaggi, Claudio E. Palazzi
The ubiquity of mobile technology has opened the door to the new era of mobile sensing. Through this new paradigm, physical phenomena can be observed in a distributed way, crowd-sourcing the data measurement tasks to smartphones and/or other popular smart wearables. Mobile sensing and wireless communications can hence be employed to gather data and generate new information and services, benefiting

Secure and anonymous authentication scheme for the Internet of Things with pairing Pervasive Mob. Comput. (IF 2.725) Pub Date : 2020-06-18 Hsiao-Ling Wu, Chin-Chen Chang, Long-Sheng Chen
The Internet of Things technology allows devices automatically connect with others or a server for the purposes of exchanging data. People can conveniently integrate data from those devices for a smart home, vehicular ad-hoc network, e-Health, etc. In 2017, Wang et al. proposed a simple authentication scheme for the Internet of Things. Although they formally proved that their scheme is secure, they
