When developing a network management system, the developer is faced with many choices concerning how to interact with the network resources and how to embed into the schema of manager agent architectures. In this paper we propose NMX (Network Management Extensions), a software framework implementation based on Java JMX (Java Management Extensions) technology and SNMP (Simple Network Management Protocol)...
Large scale sensor networks are non trivial to deploy due to their heterogeneous, distributed nature. This paper presents a technique to configure and deploy sensor applications on heterogeneous networks that is based on the use of virtual filesystem abstractions. The approach can augment existing sensor software build procedures with the ability to configure and deploy software, all using the filesystem...
Industrial automation and control systems are composed out of logically interconnected but physically separated software components. Subcomponents of such systems often require diverse communication links with different protocols and specific quality of service (QoS) constraints. These QoS requirements for communication have an important impact to the overall system design and must be considered during...
During the last years, recent technological advances enabled the development of tiny devices equipped with radio, micro controller and sensors, called sensor nodes. Collaborating networks of such devices, known as wireless sensor networks (WSNs), are subject of many researches. A couple of network centric tasks like data transmission and aggregation, self-organisation, localization and energy awareness...
Testbeds are necessary to evaluate the performance of network applications for a wide range of deployment scenarios. Especially in wireless sensor networks, where the performance highly depends on environmental conditions, traditional computer-based simulations provide validity to only limited extent. Different approaches have been carried out to develop generic testbeds for protocol evaluation, but...
Mobile communication has become the dominant branch in the communication business over the last decade and is still rapidly growing in the market. With the recent advances in wireless networks and the exponential growth in the usage of multimedia applications, multi-core platforms point to be the solution of feature-rich phones, such as the iPhone or the BlackBerry Storm to deliver the performance...
Stateful firewalls are a well-established security mechanism to restrict the traffic exchanged between networks to a certain subset of users and applications. In order to cope with new type processors types like multiple cnMIPs cores, we design an improvement high-performance software architecture based on multi-core network processor. It implements the ldquolow-layer processingrdquo strategy to design...
The principal role of embedded software is the transformation of data and the interaction with the physical world stimulus. The main concern in developing embedded software for network application is the lack of published best practice software architecture for optimizing performance by means of reducing protocol processing overhead, memory usage, and power consumption. This paper presents the implementation,...
Currently there is no widely accepted formalized description or metadata that represents networks, their components and interrelations between them. There is also no de facto classification of network parameters, models and services. The network community lacks a metadata specification similar to WSDL that represents networks in clear and unified manner and includes software, hardware and networking...
Owing to the limited requirement for sensor processing in early networked sensor nodes, embedded software was generally built around the communication stack. Modern sensor nodes have evolved to contain significant on-board functionality in addition to communications, including sensor processing, energy management, actuation and locationing. The embedded software for this functionality, however, is...
Testbeds are a key tool in the development of modern wireless communication systems. They allow evaluation of standards, algorithms and new schemes in real scenarios. Testbeds consist of two parts: the hardware, either built from tailor-made or off-the-shelf products; and the software, that includes both the control software and the algorithms to be tested. We propose a novel architecture for the...
