“…As previously mentioned, this new network coding entity will be integrated within the OConS framework, which structures the elements of the NC entity according to the following three phases [13]: information gathering (storing of coded and original packets, including overheard ones), decision taking (whether coding/decoding may be performed), and decision enforcement (the actual realization of the coding/decoding operations).…”

Since it was originally proposed by Ahlswede et al. (2000), network coding (NC) has been the focus of many research efforts and proposals. In particular, NC has been put forward as a means to increase the capacity of wireless mesh networks, by exploiting the broadcast nature of wireless links. However, in spite of the fairly large number of papers on the subject of network coding, the impact of NC on TCP performance in wireless mesh networks is still not fully understood. By means of a thorough simulation study, this paper aims thus at providing insights about the interaction between TCP's congestion control mechanisms and the underlying NC done by wireless relays. In particular, we focus on the influence of the main parameters related to the coding buffer used by such relays to encode packets. Our results suggest the feasibility of devising engineering rules for setting such parameters. Another main conclusion, in line with previous preliminary findings by the authors (Hassayoun et al., 2010) is that TCP performance can indeed be improved by the use of NC, but only as long as the wireless channel quality is above a certain level.

“…All in all, the proposals that were made around 5 years ago, although conceived so as to have a certain degree of flexibility, might not be able to solve all the new challenges and requirements which are continuously appearing. Recently, a framework to promote Open Connectivity Services has been proposed as a new paradigm to manage connectivity in the forthcoming communication scenarios.…”

This paper proposes a methodology to analyse connectivity over highly heterogeneous wireless networks. We consider a scenario comprising a large number of access elements and end users, who move and initiate different services according to some patterns. The framework that has been implemented takes periodic snapshots, each of them used to pose a different optimization problem. We take into account the intention of end users to have a connection (those with an active service), disregarding idle users, as well as the outcome of the previous problems (for instance, the base station a particular user was connected to). The feasibility of the methodology proposed in this work is assessed with a scenario over which we study different access selection strategies including the following criteria: price of resources, service affinity towards particular technologies as well as the willingness to reduce the number of handovers. The results validate the proposed methodology and highlight the impact that an appropriate design of the access selection strategy may have.

Abstract. The current Internet architecture was designed more than 30 years ago for a very different set of services than those used today. Several new architectures have been proposed for a Future Internet to better meet todays and future requirements. Content Centric Networking (CCN) is one of those new architectures gaining worldwide attention by researchers and the focus of this article. CCN is based on naming content instead of hosts allowing routers to cache popular content. It has been shown that CCN can also support point-to-point real-time conversations, for example voice or video calls. However, it has not been defined how node mobility can be achieved in such a real-time scenario with strong time constraints. In this paper a close study to the handover algorithms has been carried out. A handover decision maker, which is based on neuro-fuzzy system (NFS) is proposed and evaluated. The results show that the proposed decision maker meets the design targets.
