“…CPL [1], LESS [2], SPL [3], VisuCom [4] and DiaSpec [5] are attempts to allow end users to create services, but they are all limited to controlling call routing. Also, CPL and LESS use XML and, hence, even simple services require long programs.…”

Abstract-The SECE (Sense Everything, Control Everything) system allows users to create services that combine communication, calendaring, location and devices in the physical world. SECE is an event-driven system that uses a natural-English-like language to trigger action scripts. Presence updates, incoming calls, email, calendar and time events, sensor inputs and location updates can trigger rules. SECE retrieves all this information from multiple sources to personalize services and to adapt them to changes in the user's context and preferences. Actions can control the delivery of email, change the handling of phone calls, update social network status and set the state of actuators such as lights, thermostats and electrical appliances. We give an overview of the SECE language and system architecture.

“…DiaSim relies on the DiaGen approach [1], [2] where a high-level specification of a pervasive computing environment written in the DiaSpec language is passed to a compiler to produce a customized programming framework. This programming framework provides developers with high-level abstractions to discover services and to communicate with them.…”

Abstract-Pervasive computing applications involve both software concerns, like any software system, and integration concerns, for the constituent networked devices of the pervasive computing environment. This situation is problematic for testing because it requires acquiring, testing and interfacing a variety of software and hardware entities. This process can rapidly become costly and time-consuming when the target environment involves many entities.In this demonstration, we present DiaSim, a simulator for pervasive computing applications. To cope with widely heterogeneous entities, DiaSim is parameterized with respect to a description of a target pervasive computing environment. This description is used to generate both a programming framework to develop the simulation logic and an emulation layer to execute applications. Furthermore, a simulation renderer is coupled to DiaSim to allow a simulated pervasive system to be visually monitored and debugged.

The programmer declaratively specifies the interaction characteristics of these entities to automatically generate the framework.…”

Multi-threaded SIP servlet containers pose difficult synchronization problems to application developers. On the one hand, if a container automatically locks resources for servlets according to some fixed protocol, this protocol is not likely to be appropriate for all applications. It may degrade performance or even introduce deadlock in some applications. On the other hand, leaving application programmers to code synchronization-while flexible-is prone to error. The logic to both infer the resources a servlet requires and then to lock the required resources is complex and cross-cutting. This "synchronization logic" can easily obscure an application's "business logic." Interleaving synchronization code with business code makes an application difficult to maintain and extend.In this paper, we elaborate key dimensions of the thread synchronization problem for SIP servlet containers. We further propose a novel synchronization model for SIP servlet containers, which addresses these dimensions in a more comprehensive fashion than any existing model that we know of. Our synchronization model is highly flexible. It introduces abstractions to promote correctness, maintainabilty, and extensibility. We also describe a reference framework that implements these abstractions. To illustrate the benefits of our model, we describe a representative SIP application developed using this framework.
