Surveys show an increased reliance on physician and patient social networks, which promise to transform healthcare management. But challenges such as privacy and data accuracy remain.
Underwater wireless sensor networks consist of a certain number of sensors and vehicles that interact to collect data and perform collaborative tasks. Designing energy-efficient routing protocols for this type of networks is essential and challenging because sensor nodes are powered by batteries, which are difficult to replace or recharge, and because… (More)
Underwater Wireless Sensor Networks (UWSNs) pose many challenges due to the intrinsic properties of underwater environments such as large propagation delays, node mobility and limited bandwidth capacity of acoustic channels. In this paper we present DUCS (Distributed Underwater Clustering Scheme), a new GPS-free routing protocol for UWSNs that does not use… (More)
