A.M. Hadjiantonis, M. Charalambides, G. Pavlou, An Adaptive Service Management Framework for Wireless Networks,
published in the IEEE Vehicular Technology Magazine, special issue on Policy-based Management for Wireless Multimedia Services, Vol.2, Iss.3, p.6-13, IEEE, Sep. 2007
The paper discusses a novel framework for the management of services in wireless environments, considering their diverse requirements and conditions. Nowadays, services targeting home and business users, such as Internet access, digital television or online entertainment are taken for granted. However, our lifestyle creates the need for extending the reach of such services but also the need for new ones, targeted to people on the move. With complex wireless networks forming around us and a new range of services becoming available, an enhanced service management paradigm is required. Using a wireless Media Service as a case study, simulation results indicate that our policy-based approach offers a flexible framework where both business and user expectations are met. User preferences guide service customization while statistical processing of user requests directs service adaptation.

A. Malatras, A.M. Hadjiantonis, G. Pavlou, Exploiting Context-Awareness for the Autonomic Management of Mobile Ad Hoc Networks, published in the Journal of Network and System Management (JNSM), special issue on Autonomic Pervasive and Context-aware Systems, Vol. 15, No. 1, Springer, March 2007
The paper discusses a novel framework and its prototype deployment: Mobile Ad Hoc Networks (MANETs) are characterized by a degree of dynamicity that can result in significant drawbacks regarding their useful deployment. The fact they are formed spontaneously, comprising possibly heterogeneous devices, hinders further their wide adoption. In this paper we present the design and implementation of a system that exploits context-awareness and couples it with policy-based management in order to enable the self-management of MANETs. The key idea is to support self-configuration by being adaptive to varying conditions modeled as context, with high-level management policies driving self-configuration towards particular goals. We propose the management of the MANET in a hierarchical but also distributed manner through a dynamically constructed set of manager nodes. We present and evaluate our work on context-awareness and context dissemination in MANETs through simulation and also by deploying the prototype system in our experimental MANET testbed for a proof-of-concept application scenario.

A.M. Hadjiantonis, G. Pavlou, Policy-based Self-Management of Hybrid Ad hoc Networks for Dynamic Channel Configuration, accepted for publication at IEEE/IFIP Network Operations and Management Symposium 2008 (IEEE/IFIP NOMS 2008)
Abstract: Wireless networks have become a ubiquitous reality and ever more surround our everyday activities. They form and disappear around us spontaneously and have become new means for social interaction. At the same time, their increased complexity and heterogeneity have become barriers to their wider adoption and ease of use. It has become clear that self-management capabilities are vital for truly pervasive network management. To cater for the needs of both service providers and users, we propose a policy-based solution based on the ad hoc networking paradigm. By allowing limited infrastructure support, the notion of “hybrid ad hoc networks” emerges as a flexible extension to today’s networks. A Distributed Policy Repository provides the support for policy-based device management and devices can autonomously adapt by examining local conditions and taking corrective actions in real-time. We design a system with self-management capabilities, able to self-configure and self-optimize connectivity parameters. Our aim is to simplify the management of hybrid ad hoc networks, enabling their coexistence and integration with wireless local area networks (WLANs). Implementation and deployment on a wireless testbed have demonstrated significant performance improvement for ad hoc networks in the presence of interference. Our experiments have measured a 33% goodput increase, after switching to a non-interfering channel in real-time.

Abstract: Modern cities are becoming increasingly networked environments and a plethora of computing equipment interacts with today’s urban citizens. We refer to these ubiquitous networked environments as “urban spaces” and attempt to manage these under a unified framework based on policies. Since users actively participate in urban spaces with their owned devices and demand more control and privacy, we introduce a scheme to protect user privacy and respect their preferences. We adopt a multiple manager paradigm to enable more entities to offer their services and cooperatively shape management logic based on their objectives. Detailed policy examples illustrate the concepts and simulation results measure the effect of policies on network performance.

A.M. Hadjiantonis, A. Malatras, G. Pavlou, A context-aware, policy-based framework for the management of MANETs, Proc. of the Seventh IEEE International Workshop on Policies for Distributed Systems and Networks, May 2006 (IEEE POLICY 2006)
The paper discusses a policy-based framework for managing MANETs: Mobile ad hoc networks (MANETs) are an emerging paradigm in wireless communications that has recently attracted a lot of attention. Their inherent benefits such as unrestrained computing, lack of centralization and ease of deployment at low costs are tightly bound with relevant deficiencies such as limited resources and management difficulty. There is a need for new management approaches to handle the requirements and specific characteristics of these networks. We propose a hybrid approach, employing a hierarchical and distributed organizational model for MANET management. We adopt a policy-based network management (PBNM) approach together with context awareness and we present our system architecture that is capable of effectively managing a MANET. We present and evaluate our approach under various application scenarios.

A.M. Hadjiantonis, P Flegkas and G Pavlou, A management model for ad hoc networks Proc. of the London Communications Symposium 2005 , University College London, September 2005(LCS 2005)
Abstract: The digital revolution we are experiencing today has brought an increased penetration of wireless devices in our life. Devices of all kinds spontaneously form ad hoc heterogeneous networks which need to be managed efficiently. This task is the motivation of our research efforts and we aim to provide solutions regarding the management of mobile ad hoc networks (MANET). We propose a novel two-tier policy-based distributed and hierarchical organisational model. We introduce three node modules which relate to the physical node capabilities rather than their organisational role. These modules are the managerial entity (ME), the cluster leader (CL) and the terminal node (TN). A distributed policy repository (DPR) is implemented using LDAP and its replication functionality is exploited to achieve on the fly replication. The defined policies guide the behaviour of the system by enforcing appropriate actions when the desired conditions are met.
