Abstract:This paper aims to address the deficiencies of current internetworking to support mobility and moving networks. We present a novel approach to consider networking in general -the concept of Ambient Networks 1 -and discuss related mobility problems. We bring forth several challenges for future research demanding an architectural approach in order to reach a solution in a uniform, efficient, and integrated fashion.
The overall goal of the Ambient Networks Integrated Project is to develop a vision for future wireless and mobile networks. Even though mobility management has been investigated within numerous research and standardisation projects, the novel approach of Ambient Networks on the distribution of control space functions brings up possibilities to tailor mobility support for specific environments such as 3GPP and IEEE802 networks and on the other hand to efficiently manage the large variety of co-existing legacy and novel solutions foreseen in beyond 3G networks. The paper describes how modular design of mobility management functions can contribute to this objective. A topic, which is very much related to modularity deals with different types of communication endpoints. The paper elucidates how this discussion will help to coordinate different mobility solutions residing at different layers of the communication stack.
This Special Issue includes extended versions of selected papers from the XII Jornadas de Ingeniería Telemática (JITEL 2015), that took place in Palma, Spain, from October 14th to 16th, 2015. These papers underwent a rigorous review process, ensuring that they present enough new material so as to be considered original contributions while avoiding self-plagiarism.
In this paper we discuss aggregated mobility patterns and physical proximity of nodes within Ambient Networks, where an Ambient Network can be described as a network that integrates heterogeneous nodes and access techniques. We illustrate how awareness of node mobility patterns can be used to identify groups of nodes moving together, and how this grouping can be used to decrease signaling overhead, for example the signaling associated with a mobility event, and increase transmission efficiency. First, we describe the architectural and naming issues associated with this concept and discuss a number of mobility optimizations that can be applied to these moving networks. Further, we introduce algorithms that can recognize the presence of a routing group to enable the use of routing and mobility optimizations. Finally, we assess the performance and benefits of the routing group approach by means of simulation.
