A wireless sensor networks MAC protocol for real-time applications.

Wireless Sensor Networks (WSN) are designed for data gathering and processing, with particular requirements: low hardware complexity, low energy consumption, special traffic pattern support, scalability, and in some cases, real-time operation. In this paper we present the Virtual TDMA for Sensors (V...

In addition, duty cycle is increased or decreased in order to keep latency constant below a given deadline. Therefore, a major advantage of VTS is that it guarantees a bounded latency, which allows soft real-time applications.This work has been cofunded by the Economy, Industry and Innovation Council, with the SOLIDMOVIL project (2I04SU044), supported by Fundacion Seneca, from the Region of Murcia with the ARENA Project (00546/PI/04), with the ARPaq project (TEC2004-05622-C04-02/TCM) by the Spanish Research Council and the CSI-RHET project (TEC2005-08068-C04-01/TCM).Springer Verlag200820082008info:eu-repo/semantics/articleapplication/pdfapplication/pdfhttp://hdl.handle.net/10317/424reponame:Repositorio Digital UPCTinstname:Universidad Politécnica de Cartagena(UPCT)InglésAtribución-NoComercial-CompartirIgual 3.0 Españahttp://creativecommons.org/licenses/by-nc-sa/3.0/es/info:eu-repo/semantics/openAccessoai:repositorio.upct.es:10317/4242026-05-15T06:39:02Z
