Providing resilient inter-domain connections in multi-domain optical GMPLS networks is a challenge. On the one hand, the integration of different GMPLS domains to run traffic engineering operations requires the development of a framework for inter-domain routing and control of connections, while keeping the internal structure and available resources of the(More)
This paper surveys the most relevant works of Data Centric Storage (DCS) for Wireless Sensor Networks. DCS is a research area that covers data dissemination and storage inside an ad-hoc sensor network. In addition, we present a Quadratic Adaptive Replication (QAR) scheme for DCS, which is a more adaptive multi-replication DCS system and outperforms previous(More)
In passive optical networks employing the interleaved polling with adaptive cycle time (IPACT), the literature has focused on providing bandwidth-based service differentiation strategies. This work shows how to provide different levels of delay-based differentiation and provides a model to characterise the proportional differentiation achieved, which is(More)
The Path Computation Element WG was chartered at IETF in the beginning of 2005. The purpose of this working group is the computation of paths for MPLS-based traffic engineering across Autonomous Systems in the Internet. This paper provides a short overview of the purpose of this architecture and explores some of its possibilities in the provision of(More)
This paper studies data-centric storage (DCS) as a suitable system to perform data aggregation on wireless sensor and actor networks (WSANs), in which sensor and actor nodes collaborate together in a fully distributed way without any central base station that manages the network or provides connectivity to the outside world. The authors compare different(More)
This paper evaluates the performance of multi-domain networks under the Generalized Multi-Protocol Label Switching control framework in case of a single inter-domain link failure. We propose and evaluate a routing protocol extension for the Border Gateway Protocol, which allows domains to obtain two Autonomous System disjoint paths and use them efficiently(More)
