A Secure Collaborative Network Protocol

Autor: Denis Rosário, Hugo Lima, Raimundo Viegas, Roberto Araújo

Publikováno v: LANC

Cloud storage services allow a simple collaborative environment in which users share their files. To perform this, users state which files they want to share and who is able to access them. Recently, Silva et al. introduced an idea that does not requ

CHEATS: A cluster-head election algorithm for WSN using a Takagi-Sugeno fuzzy system

Autor: Adonias Pires, Raimundo Viegas, Dionne Cavalcante Monteiro, Eduardo Cerqueira, Claudio Silva

Publikováno v: 2011 IEEE Third Latin-American Conference on Communications.

Energy conservation is very important task for wireless sensor networks (WSN), since external power sources are typically unavailable and the replacement of batteries is clearly impractical for large networks. A classical protocol widely used in WSN,

A proposal of real-time publish-subscribe scheme compatible with 802.11e wireless networks

Autor: Raimundo Viegas, Francisco Vasques, Paulo Portugal, Luiz Affonso Guedes

Publikováno v: 2009 35th Annual Conference of IEEE Industrial Electronics.

In this paper, we propose a real-time publish-subscribe communication scheme for IEEE 802.11e networks, named Group Sequential Communication (GSC). The GSC intends to improve the HCCA mechanism by adopting a simple approach based on the Virtual Token
