This work proposes the development and application of specific security metrics for metropolitan broadband access networks that aim to measure the efficiency of security programs and support action planning against detected problems. The approach presented in this work show metrics developed for these networks and parameters for metrics definition. This paper also presents results achieved from...

In this paper, a power consumption model for both macrocell and microcell base stations is proposed. This model is validated by temporal power measurements on actual base stations and an excellent agreement is obtained. Furthermore, the power consumption’s evolution during the day is investigated by means of these measurements. The energy efficiency of three different wireless technologies is c...

It is becoming more and more apparent that the vast majority of subscribers in developing countries will be receiving wireless broadband information services through mobile terminals. To make the growth in mobile technology and services sustainable, stakeholders of the mobile value chain need to address the cost and reliability issues for mobile services. In this paper three mobile service affo...

In the open access network model, the roles of the service provider and the network owner are separated, and the service providers get access to network and the end customers on fair and non-discriminatory conditions. This should be compared to the traditional vertically integrated business model where the service provider and the network operator are the same. A large number of open access net...

having access to locations struck by natural environmental disasters is one of the chief necessities in urban disaster management. this paper aims to study different physical and semi-physical patterns for increasing access to different districts in a city through applying changes to the present network of routes. to attain this goal, district 6 of tehran municipality was selected for the case ...

In this paper we present an extension to an existing hash based packet classification technique in order to improve its performance in a distributed network access control environment. We show that such architecture can be modified so that flow states can be kept in a distributed fashion thus reducing the space needed for packet filtering in each component of the architecture. We also show how ...

This paper examines the effect of open access policy on competition in network industries under uncertainty. Comparing a competition under an open access policy with a facility-based competition, we confirm that allowing access to an essential facility makes the timing of a follower’s entry earlier than that in a facility-based competition, irrespective of the level of access charge. Furthermor...
