“…We concur with Vidales et al [4] that in heterogeneous network environments several sources of events and context information should be consulted in order to achieve seamless connectivity and develop swift mobility management mechanisms. Furthermore, earlier work in other event/notification systems [16]- [19], which introduces mechanisms on how to implement such systems, along with the evaluated event generation cases is very encouraging and complimentary to our effort in defining TMM as a specialized notification system for mobility-related events which originate from the entire protocol stack.…”

Abstract-Current protocol stacks can handle only a handful of events that may trigger actions for mobility management, such as signal strength indicators and cell load. We argue for new mechanisms that can deal with a greater variety of triggering events, which may originate from any component of the node's protocol stack as well as mobility management entities within the network. We present the main concepts that govern our trigger management mechanisms (TMM), which aim at operating in a richer mobility management framework, and enable the deployment of new applications and services. After summarizing the architectural requirements with respect to trigger collection, processing, storage, and dissemination, we introduce a real implementation of TMM on commodity mobile devices. We briefly review our testbed environment and present experimental results using TMM to drive a lossless streaming video session handover between a laptop and a PDA. We position the current TMM design and implementation within the Ambient Networks architecture, centering in particular on the use of policies to steer TMM operation, and the role that TMM can play in an information service infrastructure. Finally, we outline current and future work items.

“…Resource allocation is a very important feature of any real-time and especially embedded system due to the scarcity of resources. To this extent the research done in (Duran-Limon et al, 2003) works in developing resource management techniques utilizing aspect-oriented paradigms. RCDL managed to separate the cross-cutting concerns in a system and allowed the straightforward definition of various services.…”

Timeliness and criticality of a process are the two main concerns when designing real-time systems. In addition to that embedded systems are bounded by limited resources. To achieve these concerns while at the same time using a minimal amount or resources, real-time embedded systems use different techniques such as task scheduling, resource management and task synchronization. These techniques involve a number of the modules of the system which makes the use of Aspect-Oriented Software Development imperative. AOSD is a programming technique which uses the notion of join points to capture specific locations in code execution and then use advices to insert new code. This paper examines existing work in the development of schedulers, resource allocation agents and synchronization techniques using Aspect-Oriented Software Development in real-time embedded systems. An analysis of the existing research is used to describe the advantages of using AOSD over conventional OOP methods and to identify areas where further research may be required.

“…We also believe that in heterogeneous network environments several sources of events and context information should be consulted in order to achieve seamless connectivity and develop swift mobility management mechanisms like presented in [15]. Event/notification systems presented in [16,17], which introduce mechanisms on how to implement such systems, along with the evaluated event generation cases are very encouraging and complementary to our effort in defining TRG together with DCMF as a specialized notification system for events which originate from the entire protocol stack. Event and notification system like TRG functionality are needed also for the future Internet solution like presented in [14] As mentioned, the TRG functionality approach is close to the 802.21 [5] approach.…”

Multimedia delivery in mobile multiaccess network environments is gaining traction as a key area within the future Internet research domain. When network heterogeneity is coupled with the proliferation of multiaccess capabilities of mobile handheld devices, one can expect new avenues for the development of novel services and applications. In particular, novel mechanisms for audio/video delivery over multiaccess networks may prove to be a major disruptive technology. In this paper we present and evaluate a distributed information service, which can be used to enhance media delivery over multiaccess networks. After describing the information service, which is built upon the mobility triggering framework (TRG) and the distributed control and management framework (DCMF), we introduce our testbed which includes 3G/HSPA, WLAN and WiMAX network accesses. We present results that demonstrate the value of the proposed information service in enhancing video delivery in practice by minimizing service disruption in an involved scenario. Finally, we conclude the paper outlining future work items.
