A cloud-assisted random linear network coding medium access control protocol for healthcare applications
(2014-03)
Article
Accés obertRelay sensor networks are often employed in end-to-end healthcare applications to facilitate the information flow between patient worn sensors and the medical data center. Medium access control (MAC) protocols, based on ... -
A proxy design to leverage the interconnection of CoAP wireless sensor networks with web applications
(2015-01-09)
Article
Accés obertIn this paper, we present the design of a Constrained Application Protocol (CoAP) proxy able to interconnect Web applications based on Hypertext Transfer Protocol (HTTP) and WebSocket with CoAP based Wireless Sensor Networks. ... -
Performance evaluation of wireless sensor networks for mobile event and mobile sink
(2010-12)
Article
Accés obertExtending lifetime and energy efficiency are important objectives and challenges in-Wireless Sensor Networks (WSNs). In large scale WSNs, when the nodes are near to the sink they consume much more energy than the nodes far ... -
Runtime extension of low-power wireless sensor nodes using hybrid-storage units
(2010-03)
Article
Accés obertThe sensor nodes of wireless sensor networks remain inactive most of the time to achieve longer runtimes. Power is mainly provided by batteries, which are either primary or secondary. Because of its internal impedance, a ... -
TinyCoAP: a novel constrained application protocol (CoAP) implementation for embedding RESTful web services in wireless sensor networks based on TinyOS
(2013-05-14)
Article
Accés obertIn this paper we present the design and implementation of the Constrained Application Protocol (CoAP) for TinyOS, which we refer to as TinyCoAP. CoAP seeks to apply the same application transfer paradigm and basic features ...
