“…When a service is invoked, its content is serialized, as an XML fragment, and sent together with the associated rules to another specially designed web service that acts as a monitor. In [15] [24], the authors propose policy-based approaches to monitor web service compositions and management systems, respectively. In [15], the use of declarative policies provides flexibility and reusability when specifying a property.…”

“…In [15], the use of declarative policies provides flexibility and reusability when specifying a property. The work in [24] uses extracted information from policies to identify, configure, and instantiate management agents that will be used to monitor management systems. All the above approaches use rules or policies for monitoring the correct behavior of a system.…”

Monitoring of service-based systems is considered an important activity to support service-oriented computing. Monitoring can be used to verify the behavior of a service-based system, and the quality and contextual aspects of the services participating in the system. Existing approaches for monitoring service-based systems assume that monitor rules are pre-defined and known in advance, which is not always the case. We present a pattern-based HCIaware monitor adaptation framework to support identification, modification, creation, and removal of monitor rules based on user"s interaction with a service-based system and different types of user context. A prototype tool has been implemented to demonstrate the framework.

“…The presented work is also related to research efforts in two main research streams, namely: automated policy-based management systems [9], [10] and real-time simulation-based optimization [20], [5]. Recently, various successful approaches have been considered for policy automation such as: utilitybased, case-based and logic-based reasoning (for a comprehensive review the reader is referred to [8]).…”

“…The VHO manager maintains a list of the currently active VHO policies communicated by the simulation manger and used to configure the VHO scheme. Once the simulation manager communicates a new set of VHO configuration policies to the VHO manager, the new policies are automatically mapped [9] to configure the running VHO scheme. In our current implementation of the proposed framework, we adopted a simple VHO procedure based on the analytic hierarchy process (AHP) [12] which is used in both the simulator and network to determine the weight of each QoS factor.…”

This paper proposes a new framework for future policy-based adaptive vertical handover (VHO) in heterogeneous wireless networks. In contrast to existing, statically configured, schemes that lack the ability to quickly adapt to changing network loads, the proposed framework continuously derives optimal configuration policies with respect to handover initiation and network selection. To achieve this goal, the proposed work relies on the interactions between two components: a policy-based real-time simulator and a VHO manager. Triggered by indications of VHO performance degradation, the former enacts a set of VHO scenarios, selected based on a predefined set of simulation policies, to evaluate possible new VHO configurations before actually applying them to the real network. Based on the outcome of the simulation and the monitored network performance, a set of VHO configuration policies is communicated to the VHO manager to reconfigure and/or fine-tune the running VHO scheme. Preliminary performance evaluation results demonstrate the significant enhancement of the outcome of the proposed VHO framework in terms of reducing the ping-pong phenomenon and the handover delay.Index Terms-4G wireless networks; vertical handover; policybased management; run-time simulation.
