“…The reason for its sustained popularity is its apparent simplicity compared to SOAP. In academia XML-RPC has been used for communication of resource-contained portable devices, because it is lightweight, interoperable, easy to extend, easy to deploy and widely supported by devices [104], [105]. Its minimum requirements for XML processing and HTTPl.O were satisfied even by the most limited Java platforms, i.e.…”

Wireless ad hoc networks pose major research challenges because of their increasing ubiquity and user-initiated formation. The motivation of this thesis emanates from the need for unrestricted wireless communication in a scalable and predictable manner. This need is accentuated by the increasing users' demand for spontaneous communication and the deficiencies of existing management frameworks. The objective is to propose a management framework able to leverage the potential of wireless ad hoc networks as an alternative communication method allowing them to coexist with other networks and to emerge as their flexible extension. In the context of this thesis, Wireless ad hoc netw>orks consist of a majority of end-user devices, capable of multihop communication, and optionally supported from limited infrastructure. The policy-based management (PBM) paradigm is employed to facilitate their self-management, combining design and theory with testbed implementation and simulation studies. The thesis contribution can be identified in tlnee areas: (1) Design o f a context-aware policy hierarchy and a hybrid role-based organisation model: The integration of policies with contextual feedback enables the creation of a closed control loop at different organisational levels, forming the basis for self-management. (2) Deployment o f distributed PBM functionality: The management of wireless ad hoc networks is possible with the decentralisation of traditional PBM concepts, based on the design and implementation of a Distributed Policy Repositoiy (DPR). The DPR assists in the coordination of dispersed policy decision points (PDPs) by facilitating the synchronisation of policies and offering a uniform view of management objectives to the PDPs. (3) Validation o f PBM functionality fo r self-management: A case study addresses the deployment of a wireless ad hoc network on a testbed, attempting to overcome the lack of central coordination and the occurrence of interference, by using policies to control its dynamic channel assigmnent. Finally, the framework is extended for service management, implementing adaptable service provisioning and offering service customisation to end-users. The elements of this thesis contribution are combined under a unified policy-based framework for the self-management of wireless ad hoc networks.

This chapter presents a state of the art of the management of ad-hoc networks and is structured as follows. We introduce ad-hoc networking and the challenges of ad-hoc networking management in Section 1. We present the main management paradigms and the underlying architectures in Section 2. Several application domains including monitoring, configuration and cooperation control are covered by Section 3. Finally, Section 4 concludes the chapter with a synthesis of research orientations in this domain.

“…Programmability is also possible through the provision of suitable management interfaces that allow code to be uploaded to MNs and activated in a controllable fashion. In our recent work [11] we proposed a programmable middleware capable of dynamically deploying services and protocols in ad hoc networks.…”

We present the design and implementation of a working prototype system that enables self-configuration in mobile ad hoc networks (MANETs) by exploiting context awareness and cross-layer design principles. The driving force behind the proposed system is to allow for self-configuration of MANETs by enabling them to be adaptive to varying conditions. Emphasis is placed on describing the requirements and specifications of the supporting platform's functionality. We propose the distributed management of the MANET through a proactively constructed body of nodes in order to cope with the inherently dynamic nature of MANETs. We present our work on deploying the designed system on our experimental MANET testbed and provide results of its performance based on extended testing. IntroductionThe concept of mobile ad hoc networks (MANETs) has brought a new paradigm in communication networks and acts as an enabler for pervasive computing and communication environments. In ad hoc networks, the mobile nodes (MNs) are free to move randomly and organize themselves arbitrarily; thus, the network's wireless topology may change rapidly and unpredictably. Conventional wireless networks require some form of fixed network infrastructure (i.e. the core network) and centralized administration for their operation. In contrast, since MANETs are selfcreating, individual MNs are responsible for dynamically discovering other nodes they can communicate with. This way of dynamically creating a network often requires the ability to rapidly create, deploy and manage services and protocols in response to user demands and surrounding conditions in an equally dynamic manner.We assert that this highly dynamic environment can benefit from the emerging context-driven autonomic communications paradigm. There has been no proper previous research on deploying autonomic communication solutions in MANETs, but such aspect is important due to their inherent nature. As such, autonomic communication principles can assist in the self-management of MANETs and enable network self-configuration and optimization by utilizing context information. The latter can be used to establish the need for automatic changes (self-configuration) in accordance to high-level pre-existing rules. Context-information can be used to trigger cross-layer changes (network and application configurations) according to predefined rules, leading to autonomic decision-making.
