The actual standards used in network management to represent managed equipment or networks are not totally satisfying. To solve this problem we propose a new FDT, the B method. We believe that B method has advantages over its counterparts and will bring new ideas on subjects such as ODP concepts. To confirm our assertions, we have tested this method on a real case study, the management of a WDM network...
Paralleling the increasing traffic and the associated degradation of services in operators' networks, there have been numerous research initiatives to explore potential solutions to better optimize network resources and maintain a high quality of experience (QoE) for subscribers. Although several possible solutions do exist, the focus of this paper is to survey one specific emerging family of solutions,...
This standardization oriented paper describes the SDN (Software-Driven Networking) Enablers in the ETSI AFI GANA Reference Model for Autonomic Management & Control (an emerging standard from ETSI), and impact of Virtualization. This is because in this study we see that Autonomic Management & Control and SDN (Software-Driven Networking) share the same objective of enabling programmable, manageable,...
This paper describes an Implementation Guide for an emerging standard for autonomic management &control of networks and services, namely the ETSI AFI GANA Reference Model for Autonomic Networking, Cognitive Networking and Self-Management (an emerging standard from ETSI). The implementation guide also takes into consideration the impact of emerging paradigms such as SDN and Virtualization. This...
This paper presents and evaluates a method to localize devices that communicate using a wireless network. The distances that separate a blind node, willing to determine its position, and a set of anchor nodes, that know their locations, are evaluated using the signal attenuation (RSSI) measured on data packets. However, multipath effects, frequent in an indoor scenario, introduce randomness in signal...
Due to the success of internet and huge consuming services e.g. youtube, traffic passing through operators network is showing an exponential growth. Besides, the adopted flat rate charging policy reduces the Average Revenue Per User (ARPU) and makes the traditional actions such as the costly deployment of new equipments inefficient anymore. In order to overcome these challenges offload techniques...
Resilience and Survivability in networks is an area which is growing fast, mainly due to the fact that these vital desired properties for a network, protocol, application, or service behaviour, are now receiving a lot of attention from industry, research, academia, and standardization groups-thanks to the emergence of autonomic & cognitive management and control paradigms for the evolving networks...
In this two-part paper we describe the ongoing standardization work on designing an autonomicity-enabled mesh architecture framework. This is work in progress being carried out by the AFI (Autonomic network engineering for the self-managing Future Internet) working group of the European Telecommunications Standards Institute (ETSI). In the first part (a separate paper), we briefly described the AFI...

Positioning a device with the only help of an RF transmitter in an indoor environment is difficult because of the complexity and of the unpredictable nature of radio propagation in such a scenario. The effects of fading, multipath, shadowing make it difficult to infer distance between two points from a blind measurement of the signal attenuation. However, the Received Signal Strength Indicator (RSSI)...
