Welcome to the proceedings of the 2012 IEEE 3rd International Conference on Networked Embedded Systems for Every Application (NESEA). NESEA'12 marks a significant evolution of the NESEA vision, which expands from ‘Enterprise Application’ to the broader vision of Networked Embedded Systems for ‘Every Application’.
Orthogonal Frequency Division Multiplexing (OFDM) systems are susceptible to High Power Amplifier (HPA) nonlinearities because of the high Peak to Average Power Ratios (PAPR) in the symbols that are transmitted. Clipping or otherwise limiting these high peaks causes in-band and out-of-band distortion in the signals. This study focuses on clipping noise mitigation using iterative receivers based on...
One of the main factors limiting the performance of Networks-on-Chip is congestion. Routing algorithms perform an important role in distributing the traffic load over the network by providing alternative routing paths. The major parts of research works avoid congestion by considering the traffic condition in the forward paths and delivering packets through less congested paths. However, they do not...
The paper describes a new method for the synthesis of the application specific distributed control systems, constructed using the FPGA devices. The initial steps of the proposed control algorithm rely on the notion of a Petri net, which is an easy way to describe parallel processes. The subsequent steps of the algorithm consist in the decomposition of a given Petri net - with the use of a coloring...
Managing critical infrastructures under the growing cyber-threat is becoming a matter of international urgency. The volume and frequency of cyber-related incidents on the rise yearly, and the level of sophistication is increasing. Critical infrastructures are key service providers and heavily interconnected, meaning any damaging impact would result in devastating consequences and potential cascading...
Wireless Sensor Networks (WSN) consists of small sensor devices with sensing, processing and communication capabilities. Sensor nodes are operated by batteries. As the replacement of these batteries are not practical, this network is very much energy sensitive. Resource coordination is an important issue to make this system energy efficient. Sensor nodes can be applied in various applications. Object...
The challenges involved in designing a wireless Vision Sensor Node include the reduction in processing and communication energy consumption, in order to maximize its lifetime. This work presents an architecture for a wireless Vision Sensor Node, which consumes low processing and communication energy. The processing energy consumption is reduced by processing lightweight vision tasks on the VSN and...
The verification of Spatio-Temporal Role Based Access Control policies (STRBAC) during the early development life cycle improves the security of the software. It helps to identify inconsistencies in the Access Control policies before proceeding to other phases where the cost of fixing defects is augmented. This paper proposes a formal method for an automatic analysis of STRBAC policies. It ensures...
The paper is concentrated on behavioral and structural specification of reconfigurable logic controllers (RLC). The initial description is given as a hierarchical modular control interpreted Petri net. On the abstract level of the logic synthesis specification is written in propositional sequent language. Rapid modeling and synthesis in FPGA can be done directly from expressions, written in the hardware...
The deployment of complex, multi-threaded sensor network applications is growing rapidly (e.g there are dual-core sensor mote platforms such as the Microsoft m-platform). This paper argues that parallelism can benefit networked sensors, particularly if it is based on a safe approach, i.e., follows a deadlock-free paradigm. Sensor network applications should be deadlock-free because applications running...
Mobile phone based drifters offer distinct advantages over those using custom electronic circuit boards. They leverage the inexpensive and modern hardware provided by the mobile phone market to supply water resource scientists with a new solution to sensing water resources. Mobile phone based drifters strategically address in situ sensing applications in order to focus on the large scale use of mobile...
The Wireless Sensor Network (WSN) Data Centric Storage (DCS) scheme is a promising alternative to External Storage (ES) and Local Storage (LS) schemes because the ES and LS schemes may lead to high overhead and latency. The DCS scheme, however, might incur high update traffic due to the lack of an optimally synchronized routing algorithm. This paper presents a new distributed Sector Based Distance...
The area of human digital memories focuses on documenting our entire lifetime. Using this outlet, a diverse range of information can be brought together, such as photos, location, temperature and physiological information. Nowadays, we have access to a number of different data sources, thus allowing more dynamic and data rich memories to be created. In particular, the inclusion of physiological data...
This paper demonstrates how an Irrigation Management System (IMS) can practically be implemented by successfully deploying a Wireless Sensor Network (WSN). Specifically, the paper describes an IMS which was set up in Manja Township, City of Blantyre based on an advanced irrigation scheduling technique. Since the system had to be self-sustained in terms of power, which is a challenge for deployment...
The application of run-time evolvable software stacks promises an increase in the lifetime of wireless sensor network deployments. Besides supporting changing application requirements, said systems allow the underlying platforms to adapt to new environments by replacing system and communication services at runtime. These dynamics across various software layers however complicate the provision of accurate...
The smart home paradigm is a promising new trend of research aiming to propose an alternative to postpone the institutionalization of cognitively-impaired silver-aged people. These habitats are intended to provide security, guidance and direct support services to its resident. To be able to fulfill this important mission, a smart home system first has to identify the ongoing activities of its user...
Many adaptive routing protocols have been developed for Networks -on-Chip to improve the network performance by traffic reduction. In this paper, we present an adaptive routing algorithm based upon the Q-routing, which distributes traffic by a learning method in the entire network. The learning method utilizes local and global traffic information and can select the minimum latency path to the destination...
