Abstract

Seamless computing and service sharing in community networks have been gaining momentum due to the emerging technology of community network clouds (CNCs). However, deploying and running services in CNCs confront enormous challenges such as the dynamic nature of micro-clouds, limited capacity of nodes and links, asymmetric quality of wireless links, geographic singularity based deployment model rather than network QoS based, etc. CNCs have been increasingly used by network-intensive services which exchange significant amounts of data between nodes, therefore their performance heavily relies on the available bandwidth resource in a network. The main goal of this work is to study and design a novel network-aware service placement algorithm which aims to outperform and replace the current organic (random) placement scheme adopted by Guifi.net community network.

Bio Mennan Selimi is pursuing a joint doctorate in Distributed Systems (EMJD-DC) between UPC -BarcelonaTech and IST / INESC-ID Lisbon. His current interests include distributed systems, cloud computing and wireless mesh networks. He received his Masters degree in Computer Engineering from Sapienza University of Rome, in 2011.
