The major challenge in future mobile networks is how to improve throughput to support the increase demand in traffic. Software Defined Networks is the new technology proposed but so far it has been proposed to be integrated in the current 4G architecture without major changes. However, we present the mobile networks beyond 4G where Software Defined Network(More)
The main drivers for the mobile core network evolution is to serve the future challenges and set the way to 5G networks with need for high capacity and low latency. Different technologies such as Network Functions Virtualization (NFV) and Software Defined Networking (SDN) are being considered to address the future needs of 5G networks. However, future(More)
—A major challenge of future mobile networks is providing the needed elastic scaling to the increased traffic demand, number of users and applications with acceptable cost. Another challenge is suitability for numerous communications applications while curbing unwanted traffic on the air interface and the mobile devices. This paper proposes a vision of how(More)
In this paper, we describe the integration of Software Defined Networking (SDN) in the mobile backhaul as a disruptive approach to streamline the transport network. In this work we leverage SDN to optimize the mobile backhaul transport by removing all mobile specific tunnelling and replace it with more efficient MPLS or Carrier Grade Ethernet deployed(More)
– This paper discusses the problem of interoperability of IP Telephony and Switched Circuit Networks in the area of routing information. We describe and analyze a solution for directory-based routing. We will present an architecture based on a distributed database on the switched circuit network and the IP network. The aim of the solution is to provide(More)
— Ad Hoc networking is a rather old technology that is gaining a lot of momentum in the research community. It is still an area under development and there are several proposals for the technology regarding routing protocols, addressing, interoperability, etc. Because of the extreme conditions where Ad Hoc networks should operate, it is envisioned that in(More)
Ad hoc networking is a technology still under development and there are several proposals for defining the most suitable routing protocol. The dynamic conditions of ad hoc networks do not allow having a single routing protocol that fits all possible environments. This paper presents the design of a scalable ad hoc routing protocol. The analysis of existing(More)
