“…In order to provide a lightweight Core that can run on small devices, some of the FarGo components were omitted in the Cores that run on the NLPCs, including the monitoring facility (outside the scope of this paper, see [3]) and all system complets (including the shell). The main additions to the original architecture of FarGo are the Disconnected Manager (DM, explained below), the DA-referencing layer and the DA API 3.…”

“…In this paper we present FarGo-DA, which extends the FarGo mobile framework [5,6,3,1] with support for Disconnected Aware (DA) applications. FarGo-DA provides a programming model for specifying disconnected-aware policies as part of the application, using a simple API; it extends the FarGo compiler with translation rules from DA annotations into FarGo-DA system calls; and it provides an infrastructure that implements and carries out these system calls at runtime.…”

A b s t r a c tThe emergence of networked lightweight portable computing devices can potentially enable accessibility to a vast array of remote applications and data. In order to cope with shortage of local resources such as memory, CPU and bandwidth, such applications are typically designed as a thinclient thick-server applications. However, another highly desirable yet conflicting requirement is to support disconnected operation, due to the low quality and high cost of on-line connectivity. We present a novel programming model and a runtime infrastructure that addresses these requirements by automatically reconfignring the application to operate in disconnected mode of operation, when voluntary disconnection is requested, and automatically resorting to normal distributed operation, upon reconnection. The programming model enables developers to design disconnected aware applications by providing a set of component reference annotations with special disconnection and reconnection semantics. Using these annotations, designers can identify critical components, priorities, dependencies, local component alternatives with reduced functionality, and state merging policies. The runtime infrastructures carries out dis-and re-connection semantics using component mobility and dynamic application layout. The disconnected operation framework, FarGo-DA, is an extension of FarGo, a mobile component framework for distributed applications.

“…For example, in FarGo [15] this component is known as a core and in most systems separate runtimes are required to allow different applications to run independently, although this is not the case with MobJeX, which can run multiple applications in a single runtime using threads. The applications themselves comprise mobile objects, which interact with each other through proxies [14].…”

This paper proposes, implements, and evaluates in terms of worst case performance, an online metrics collection strategy to facilitate application adaptation via object mobility using a mobile object framework and supporting middleware. The solution is based upon an abstract representation of the mobile object system, which holds containers aggregating metrics for each specific component including host managers, runtimes and mobile objects.A key feature of the solution is the specification of multiple configurable criteria to control the measurement and propagation of metrics through the system. The MobJeX platform was used as the basis for implementation and testing with a number of laboratory tests conducted to measure scalability, efficiency and the application of simple measurement and propagation criteria to reduce collection overhead.
