EMMON - EMbedded MONitoring

Despite the steady increase in experimental deployments, most of research work on WSNs has focused only on communication protocols and algorithms, with a clear lack of effective, feasible and usable system architectures, integrated in a modular platform able to address both functional and non–functional requirements. In this paper, we outline EMMON [1], a full WSN-based system architecture for large–scale, dense and real–time embedded monitoring [3] applications. EMMON provides a hierarchical communication architecture together with integrated middleware and command and control software. Then, EM-Set, the EMMON engineering toolset will be presented. EM-Set includes a network deployment planning, worst–case analysis and dimensioning, protocol simulation and automatic remote programming and hardware testing tools. This toolset was crucial for the development of EMMON which was designed to use standard commercially available technologies, while maintaining as much flexibility as possible to meet specific applications requirements. Finally, the EMMON architecture has been validated through extensive simulation and experimental evaluation, including a 300+ nodes testbed

EMMON: a system architecture for large- scale, dense and real-time WSNs

In spite of the significant amount of scientific work in Wireless Sensor Networks (WSNs), there is a clear lack of effective, feasible and usable WSN system architectures that address both functional and non-functional requirements in an integrated fashion. This poster abstract outlines the EMMON system architecture for large-scale, dense, real-time embedded monitoring. EMMON relies on a hierarchical network architecture together with integrated middleware and command&control mechanisms. It has been designed to use standard commercially– available technologies, while maintaining as much flexibility as possible to meet specific applications’ requirements. The EMMON WSN architecture has been validated through extensive simulation and experimental evaluation, including through a 300+ node test-bed, the largest WSN test-bed in Europe to dat

3rd International Workshop on Object Orientation in Operating Systems

This paper presents a design for the use of DSM techniques and system-supported synchronisation to support shared access to persistent objects in a distributed environment. We adopt a hybrid approach where the system granularity is sometimes pages and sometimes objects. We are interested in providing shared access to small (i.e., less than a page) objects in a general purpose, language-independent environment, and supporting both DSM and RPC object access mechanisms. 1 Introduction Object-oriented systems have traditionally relied on remote procedure calls (RPC) as the fundamental method for accessing remote objects in distributed environments. However, the RPC model of shipping invocations to an object can be limiting, preventing, for example, simultaneous legal accesses to copies of an object on multiple nodes

19th IEEE Real-Time Systems Symposium Work-in-progress Session

This paper describes an architecture that addresses common problems found in systems supporting QoS specification and enforcement, such as lack of flexibility and expressiveness in the specification of requirements and dependencies on specific platforms. The Quartz QoS architecture aims to solve these problems by adopting a highly extensible and platform-independent design

Proceedings of the 5th International Conference on Generative Programming and Component Engineering, GPCE\u2706

This paper presents YABS, a novel domain-specific language for defining entity behavior in pervasive computing environments. The programming model of YABS is inspired by nature and, in particular, the observations made by the French biologist Grasse on how social insects coordinate their actions using indirect communication via the environment, a phenomenon that has become known as stigmergy. Following this approach yields a simple yet expressive language that abstracts the complexities of dealing with the variety of underlying technologies typical of pervasive computing environments and that facilitates the incremental construction and improvement of solutions while providing high-level constructs for defining the behavior of entities and their coordination. We show how YABS has been used to program a number of pervasive computing applications both deployed and simulated

Using trust for secure collaboration in uncertain environments

The SECURE project investigates the design of security mechanisms for pervasive computing based on trust. It addresses how entities in unfamiliar pervasive computing environments can overcome initial suspicion to provide secure collaboration
