“…Therefore, while deploying software in a pervasive environment, it is necessary to enable the software to provide services normally even in a dynamic environment. Hoareau and Mahéo [17] adopts a deployment descriptor to depict the component's resource restraints and location restraints. After obtaining the deployment descriptor, each computer announces the components which are suitable for being installed on it according to its resource and location conditions.…”

In the pervasive e-business applications covering large geographical areas and involving many RFID readers or sensors, broker deployment strategies have a direct effect on the deployment cost and collaboration efficiency. By analyzing the deployment cost and collaboration basis, this paper proposes a model for the broker deployment problem, and presents two heuristic algorithms for the multi-object optimization of broker deployment, where one is for the deployment area which contains the zones forbidden to place brokers in, and the other is for the deployment area without any forbidden zone. Experiments are conducted to demonstrate the effectiveness of the proposed algorithms. The experimental results also show the deployment algorithms have the advantage of being low cost of deployment. Moreover, the brokers deployed carry relatively balanced loads and messages are forwarded from an event source to a broker over a small number of hops.

“…Hence, the loading of objects is made transparent to user applications, which simply see them as new implementations of already-known interfaces. The framework described in [24], addresses the distribution and deployment of components throughout the ubiquitous networking environment. It provides developers with an architecture description language to specify constrains on components, which can be considered at deploy time to find a distribution scheme satisfying all constraints.…”

“…Issues related to the design/development of ubiquitous systems have been largely discussed in literature, and many middleware, providing different types of abstraction -e.g., objects [15], components [24], and services [12] -have been proposed to deal with them. Departing from these approaches, ubiREST tackles the problem by adhering to REST principles [18]: addressability, statelessness, connectedness, and uniformity.…”

“…The work presented in [11] seeks to find deployment solutions in dynamic environments. The focus is on deploying a hierarchical component (which is an assembly of components treated as a single unit), while ensuring the deployment of individual monolithic units do not violate architectural constraints of the platform and the network before deploying that component.…”

Component-based middleware, such as the Lightweight COR-BA Component Model, are increasingly used to implement large-scale distributed real-time and embedded (DRE) systems. In addition to supporting the quality of service (QoS) requirements of individual DRE systems, component technologies must also support bounded latencies when effecting deployment changes to DRE systems in response to changing environmental conditions and operational requirements.This paper makes three contributions to the study of predictable deployment latencies in DRE systems. First, we describe OMG's Deployment and Configuration (D&C) specification for component-based systems and discuss how conventional implementations of this standard can significantly degrade deployment latencies. Second, we describe architectural changes and performance optimizations implemented within the Locality-Enhanced Deployment and Configuration Engine (LE-DAnCE) implementation of the D&C specification. Finally, we analyze the performance of LE-DAnCE in the context of component deployments on 10 nodes for a representative DRE system consisting of 1,000 components. Our results show LE-DAnCE's optimizations provide a bounded deployment latency of less than 2 seconds with 4 percent jitter.
