Mobility Model has drawn more and more attentions since its important role in Delay/Disruption Tolerant Networks (DTNs) routing protocol performance evaluation. In this paper, we first present a survey of various mobility models, and then analyze the movement characteristics in the disaster rescue scenario in detail. After that, we introduce a novel mobility model, the Random Way Point with Attraction...
Scalability is one of the most challenging problems in the current routing system. Locator/Identifier Split idea is considered as a promising way to solve the scalability issue. However, how to design a scalable and secure mapping service system in the Locator/Identifier separation context is still an unresolved problem. In this paper, we present a scalable and secure Identifier-to-Locator mapping...
Presently, the most common egress selection algorithm that we used in transit AS (Autonomous System) is hot-potato algorithm. However, the hot- potato algorithm has many problems which have been discussed in some papers. Prior research has considered a range of possible techniques, but has mostly focused on how to make the best static assignment. There is a need for good model and framework that consider...
This paper presents an optimization mechanism to facilitate efficient selection of BGP egress for an AS, when IGP link state changes. Most mechanisms for BGP egress selection have primarily focused on achieving an optimized goal by considering it as a static problem, which leads to inflexibility to variations in the topology of an AS, especially for link failures which often occur in an AS network...
Hot-potato routing is a mechanism employed in the border gateway protocol (BGP), when the BGP selects the interdomain egress with the closest egress point based on intradomain path costs. Recent work has shown that it can impact the robustness of interdomain routing especially for large ISP backbones. Some mechanisms have been proposed to replace the hot-potato routing such as interdomain traffic...
