TL;DR: Those common characteristics that impair communication in high-stress environments and then evaluates their importance in the underground mine environment are outlined and wireless sensor network based communication and location sensing systems that could potentially address current challenges are explored.

TL;DR: This work demonstrates a scheme for secret-key generation able to construct shared keys with near-perfect agreement, thereby avoiding reconciliation costs, and demonstrates in several representative body-worn settings that this scheme can generate secret bits with 99.8% agreement.

TL;DR: It is shown that radio transceivers operating at dual widely spaced radio frequencies and through spatially separated antennas offer robust communication, high link diversity, and better interference mitigation and can significantly improve end-to-end delivery rates, network stability, and transmission costs at only a slight increase in energy cost over a single radio.

TL;DR: This paper is the first to integrate confidentiality and DoS-attack-resistance in a multi-hop code dissemination protocol, based on Deluge, an open source, state-of-the-art code dissemination Protocol for WSNs and provides a performance evaluation in terms of latency and energy consumption.

TL;DR: This work is the first to demonstrate the feasibility of generating high quality secret keys with zero reconciliation cost in body-worn networks for healthcare monitoring, and develops a method to restrict key generation to periods of channel fluctuation, ensuring near perfect key agreement.
