This paper presents an enhanced version of a self-optimizing algorithm that tunes the HandOver (HO) parameters of a LTE (Long-Term Evolution) base station in order to diminish the negative effects that can be introduced by handover (radio link failures, HO failures and ping-pong handovers) and improve the overall network performance. ...Download Now
In this paper, the authors present a simple case study on energy efficiency in IP-over-WDM networks with dynamic circuit capability and compare two different load adaptive schemes, referred to as switch-on and switch-off. While the switch-off technique was already proposed for energy conservation, the switch-on approach is a new paradigm ...Download Now
The authors present an novel analytical framework for modeling current IP offloading schemes and show their comparative performance. They analyze relevant parameters, including IP routing re-convergence time, the number of affected IP routes, and the cost of circuit capacity used for offloading. Their results show that emerging offloading solutions based ...Download Now
The authors present a framework to facilitate the inter-domain multipath routing for carrier networks that are based on circuit switching technologies, without significant changes to the existing inter-domain protocols. They first introduce a simple mechanism, namely, Single Routing Plane Multipath (SRPM) which can be easily implemented in the existing PCE-based ...Download Now
