Applications of cooperative WSN in homecare systems

Cooperation plays the crucial role in shared space of the homecare processes. It is a rather hard task to ensure effective cooperation in home care environment. This is due to variability of schedules, tasks and mobility of both patients and carers. In this paper, we discuss sensor network technology that can facilitate and improve home care cooperation scenarios. We present methodology, recommendations and applications for incorporating a WSN based solution in various areas of Homecare. We argue that even the most difficult areas of cooperation between patients and their carers such as: information retrieval, information dissemination, scheduling, coordination of short and long-term treatment can be supported by WSN based solutions. Finally, we discuss sensor network design approaches for incorporating smart communication devices and sensors to support health care workers and their patients in their daily activities. The network of smart sensors can help to maintain awareness of the activities of all stakeholders and the need to integrate communication and computer technology with the requirements of effective aged care infrastructure. © 2008 IEEE

3TZ collaborative team environments incorporating the hybrid holonic architecture

The paper describes a business reengineering process (BPR) approach to address multi-timezone (3-timezone or 3TZ) collaborative teamwork environments by combining the Holonic architecture with the Zachman Metamodel Framework. While the use of collaborative project systems is not new, the methodology to share time resources from different timezones seeks to address pedagogical and engineering process concerns in team-based project development. The benefits of collaborative project management tools go beyond a uniform platform to deploy project resources, but to also enhance systemic processes and engineering practice. This facilitates team members to dedicate their time towards common work tasks, delineates individual and shared work packages, and improves student-tutor feedback techniques as teachers can actively monitor progress of development throughout the project lifecycle. © 2010 IEEE

Directed cooperation in multihop wireless sensors network

This paper proposes a relational abstraction for Wireless Sensors Network where node can identify its neighbors around it. Because of limited radio link range only some of nodes have a direct contact with the base station and transmission is carried out in a multihop way so information is send from one node to another towards the BS. We propose a relation π that represents cooperation between nodes and takes advantages of topological properties of the network. Based on the hop-distance from the BS any node k can determine a set N<(k) that consists of nodes to which/k should send messages in order to retain a data-flow direction towards the BS

Enabling Design of Middleware for Massive Scale IOT-based Systems

Recently, the Internet of Things (IoT) technology has rapidly advanced to the stage where it is feasible to discover, locate and identify various smart sensors and devices based on the context, situation, characteristics, and relevancy to query for their data or control actions. Taking things a step further when developing Large Scale Applications requires that two serious issues be overcome. The first issue is to find a solution for data sensing and collection from a massive number of various ubiquitous devices when converging these into the next generation networks. The second important issue is to deal with the “Big Data” that arrive from a very large number of sources. This research emphasizes the need for finding a solution for a large scale data aggregation and delivery. The paper introduces biomimetic design methods for data aggregation in the context of large scale IoT-based systems

People Lifting Patterns—A Reference Dataset for Practitioners

Many health professionals do not use correct person transfer techniques in their daily practice. This results in damage to the paraspinal musculature over time, resulting in lower back pain and injuries. In this work, we propose an approach for the accurate multimodal measurement of people lifting and related motion patterns for ergonomic education regarding the application of correct patient transfer techniques. Several examples of person lifting were recorded and processed through accurate instrumentation and the well-defined measurements of kinematics, kinetics, surface electromyography of muscles as well as multicamera video. This resulted in a complete measurement protocol and unique reference datasets of correct and incorrect lifting schemes for caregivers and patients. This understanding of multimodal motion patterns provides insights for further independent investigations

Anticipatory biomimetic middleware

Anticipatory, multi-agents based and biology inspired middleware for resource constrained systems such as the sensornets is able to provide infrastructure oriented services with anticipatory system properties such as: (1) self-organization, (2) self-shaping, (3) self-monitoring and self-healing. The paper aim is to explain how these fundamental properties, if imprinted on executing agents, can help in the construction of robust, cooperative and sustainable information services for infrastructure oriented software. This can occur through the application of the selected immune-computing and allometric paradigms. © 2010 American Institute of Physics

SNIPER: A Wireless Sensor Network simulator

Wireless Sensor Networks (WSN) is fast becoming the holy grail of digital surveillance, data monitoring and analysis. Being relatively cheap, lowpowered and easy to deploy WSNs is being adopted in a range of different fields. Currently, the focus is towards optimizing techniques used to form sensor clusters and to route data within a network. In order to satisfy these goals a significant amount of research is being done globally and what tends to be lacking at times is the right tools to make such research work less time consuming and inexpensive. The use of simulation tools is one such adaptation that can help researchers closely analyse a particular aspect of WSN while sticking with a known environment that is applicable to other scenarios in a similar way. This paper presents the performance and features of WSNSim, a WSN Simulator and the immediate advantages that can be experienced by researchers working on various realms in this area. © 2009 Springer-Verlag Berlin Heidelberg

Development of software with cloud computing in 3TZ collaborative team environment

In the global economy, we have seen a decrease in the barriers towards communication across the globe along with an increase of service availability to support this communication. Software development is one discipline that is capable of effectively utilizing and benefiting from global collaboration prospect lent by ever increasing capability of information and communication technology. 24-hour continues development is ideal for application towards tasks that have hard-deadlines or require work completed as soon as possible. This article will mainly focus on introducing 24/7 global models that can be applied in cloud environment used in three different time zones. The case study related to developing agricultural software has been investigated in this article. © 2011 IEEE
