Felix presented our work about incentive-based resource assignment in cloud infrastructures built in community networks at IEEE AINA 2014 (May 13-16, 2014 in Victoria, Canada). This involved my work with Umit Buyuksahin and Felix Freitag on Clommunity project. Here is the abstract of the paper:
Wireless community networks are a successful example of a collective where communities operate ICT infrastructure and provide IP connectivity based on the principle of reciprocal resource sharing of network bandwidth. This sharing, however, has not extended to computing and storage resources, resulting in very few applications and services which are currently deployed within community networks. Cloud computing, as in today’s Internet, has made it common to consume resources provided by public clouds providers, but such cloud infrastructures have not materialized within community networks. We analyse in this paper socio-technical characteristics of community networks in order to derive scenarios for community clouds. Based on an architecture for such a community cloud, we implement a prototype for the incentive-driven resource assignment component, deploy it in a testbed of community network nodes, and evaluate its behaviour experimentally. Our evaluation gives insight into how the deployed prototype components regulate the consumption of cloud resources taking into account the users’ contributions, and how this regulation affects the system usage. Our results suggest a further integration of this regulation component into current cloud management platforms in order to open them up for the operation of an ecosystem of community cloud.

I presented our work about simulating cloud infrastructures built in community networks at CNBuB 2013 (October 7, 2013 in Lyon, France). This involved my work with Leila Sharifi, Luís Veiga and Leandro Navarro, related to Clommunity project. Here is the abstract of the paper:
Community networks offer a shared communication infrastructure where communities of citizens build and own open networks. While the IP connectivity of the networking devices is successfully achieved, the number of services and applications available from within the community network is typically small and the usage of the community network is often limited to providing Internet access to remote areas through wireless links. In this paper we propose to apply the principle of resource sharing of community networks, currently limited to the network bandwidth, to other computing resources, which leads to cloud computing in community networks. Towards this vision, we review some characteristics of community networks and identify potential scenarios for community clouds. We simulate a cloud computing infrastructure service and discuss different aspects of its performance in comparison to a commercial centralized cloud system. We note that in community clouds the computing resources are heterogeneous and less powerful, which affects the time needed to assign resources. Response time of the infrastructure service is high in community clouds even for a small number of resources since resources are distributed, but tends to get closer to that of a centralized cloud when the number of resources requested increases. Our initial results suggest that the performance of the community clouds highly depends on the community network conditions, but has some potential for improvement with network-aware cloud services. The main strength compared to commercial cloud services, however, is that community cloud services hosted on community-owned resources will follow the principles of community network and will be neutral and open.

Watch out for International Multitopic Conference 2009 that is coming up in December and will be held in Islamabad. The call for papers is now closed, though.
Here is the except from the conference website:
The International Multitopic Conference 2009 (INMIC-2009) will be held in Islamabad, on 14-15 December 2009. It will be jointly organized by Mohammad Ali Jinnah University, Islamabad, and University of Engineering and Technology, Taxila, in association with IEEE Islamabad Section. Proceedings of INMIC 2009 conference will be published and the papers will also be available through IEEE Xplore ®.
IEEE INMIC is held every year and INMIC 2009 will be the 13th in the series. INMIC has become Pakistan’s flagship technical conference with a broad scope, thereby inviting interest of a large audience. The conference targets research presentations by academic and professional researchers, and also includes a series of tutorials, enabling participants to learn about the latest trends in technology. Research contributions are expected from the participants, covering various disciplines under IEEE’s domain, including technical papers, panel discussions, tutorials and project exhibitions.
