We propose a novel information-diffusion-based routing (IDBR) scheme in wavelength routed WDM mesh networks. The IDBR scheme has the fast convergence and the low bandwidth consumption of OSPF-TE while requires lower computational complexity as RIP.
We study the scaling laws for wireless ad hoc network in which the distribution of nodes in the network is homogeneous but the traffic is heterogeneous. More specifically, we consider the case in which a node is the sink to k sources sending different information, while the rest of the nodes are part of unicast communications with a uniform assignment of source-destination pairs. We prove that the...
The Internet access from vehicular networks is gaining great interest from the research community. In fact, vehicles should be able to connect to the Internet and communicate with different networks through gateways. Guaranteeing safety on the roads is the main objective of vehicular networks. Safety applications need to collaborate with other types of services for efficient safety assurance. Consequently,...
In the Internet, with many competing networks each trying to optimise its own bandwidth, a stub network has limited knowledge about user demands, available network resources and routing policies of other networks. This uncertainty makes the task of interdomain traffic engineering for a stub network very challenging. The basic aim of a stub network connected to multiple ISPs (multihomed) is to load...
This article focuses on the problem of dynamic and distributed shared path protection (SPP) in all-optical GMPLS networks without wavelength conversion capability. In this scenario, both working and backup lightpaths use a single wavelength for all links in their respective paths (i.e., wavelength continuity constraint, WCC). The novelty of this work, from the best of our knowledge, is twofold: presenting...
