In many research labs, WDM PON access networks are considered as the next generation optical access. WDM PONs are more adaptable to future technologies than conventional PONs due to their high transmission capacity and their optical transparency. An elementary design concept is the paradigm that defines at least one wavelength for each user. A design tool is presented to analyze all technologically...
The goal of this contribution is to show which practical routing approach, for wireless mesh network (WMN) backhaul, is the best for systems presenting a constraint on the total power to be emitted be network nodes by modeling rounting as a power allocation problem. We consider at first multiple-input multiple-output (MIMO) point-to-point capacity-achieving codes, and nodes cooperation. Furthermore...
An algorithm for self-organization that assigns the channels intelligently in multi-radio wireless mesh networks (MR-WMN) is important for the proper operation of MR-WMN. The aim of the self-organization algorithm is to reduce the overall interference and increase the aggregate capacity of the network. This can be possible by addressing the two major challenges that are associated with the self-organization...
rdquoThe use of the Internet must be able to be in confidence for users but security provisioning has a cost for ISPs'. In a mobility context this security must be set up from scratch after each handover and for each customer. Therefore, a mechanism has been designed in the standardization bodies: the Context Transfer. This mechanism aims to transfer suitable information between equipments in order...
