Provision of Personalized Ubiquitous Healthcare Services over NGN Using Always Best Connected Service Provider

This paper presents a personalized middleware for mobile eHealth (mHealth) services for use in the Ubiquitous Consumer Wireless World (UCWW). The middleware was developed based on the ISO/IEEE 11073 personal health data (PHD) standards. It works as a multi-agent system (MAS) to provide intelligent collection of physiological data from medical sensors attached to human body, and subsequent sending of gathered data to a log data node by utilizing the Always Best Connected and best Served (ABC&S) communication paradigm. A number of design issues associated with the middleware implementation are outlined

Inter-domain mobility with LISP-MN:a performance comparison with MIPv6

In this work, we aim to evaluate Locator Identifier Separation Protocol-Mobile Node (LISP-MN) performance in an inter-domain mobility scenario for both multi-interface and single interface MN with focus on throughput, handover delay, service disruption time and packet loss. To serve as the benchmark for performance, we compare LISP-MN with the IETF standardised MIPv6. We implement the 2 protocols on a laboratory testbed comprising all the nodes necessary for their operation. For multi-interface MNs, LISP-MN shows a better response in soft handover scenarios in terms of throughput and packet loss. MIPv6 on the other hand shows shorter handover delay with lower service disruption time in a hard handover scenario. Both protocols demonstrate poor performance for a single interface MN due to the long handover delay experienced. Although LISP-MN’s handover control messages doubled that of MIPv6, our experiments show that it takes a similar time as MIPv6 to complete the handover message exchange

Methodology for the Tariff Formation in Railway Freight Transport

Tariff policy outline and the formation of prices for services in freight transport currently lie in the competencies of individual carriers. Price formation in freight transport is fully liberalized and it has contributed mainly to a fair competition and a more effective acquisition activity of railway undertakings. In EU countries, tariffs in railway freight transport are still important today and are applicable in the form of commercial tariffs for individual railway carriers. The aim of this paper is to propose a methodology for the tariff formation in railway freight transport, taking into account the specific technical and technological requirements for transport and costs. The proposed methodology represents the scientific procedures for the efficient design of tariffs for rail freight. The scientific methods used in the methodology are focused on demand analysis, identification of the vehicle fleet, determination of employees, technology of individual shipments, cost calculation and calculation of rates, establishment of price-lists and setting the price of transportation
