Over the last couple of decades, clustering-based protocols are believed to be the best for heterogeneous wireless sensor networks (WSNs) because they work on the principle of divide and conquer. In this study, the authors propose and evaluate two new clustering-based protocols for heterogeneous WSNs, which are called single-hop energy-efficient clustering protocol (S-EECP) and multi-hop energy-efficient clustering protocol (M-EECP). In S-EECP, the cluster heads (CHs) are elected by a weighted probability based on the ratio between residual energy of each node and average energy of the network. The nodes with high initial energy and residual energy will have more chances to be elected as CHs than nodes with low energy whereas in M-EECP, the elected CHs communicate the data packets to the base station via multi-hop communication approach. To analyse the lifetime of the network, the authors assume three types of sensor nodes equipped with different battery energy. Finally, simulation results indicate that the authors protocols prolong network lifetime, and achieve load balance among the CHs better than the existing clustering protocols. © The Institution of Engineering and Technology 2014.

A body area network is a wireless network of biomedical sensors that are attached to a human body. The aim of wireless body area network (WBAN) is to facilitate continuously recording and monitoring of a person′s health condition, if needed, over a long-distance communication network. A sensing system is to be worn by the individual for a long duration. The hardware must be compact and light. This limits the size of the battery. These factors have made energy the most critical resource in WBAN and extending system lifetime has become a priority to fully realize the capabilities of WBAN. This paper presents design and system integration of WBAN technology along with issues and technical challenges of WBAN.

Pattern recognition and Gesture recognition are the growing fields of research. Being a significant part in non verbal communication hand gestures are playing vital role in our daily life. Hand Gesture recognition system provides us an innovative, natural, user friendly way of interaction with the computer which is more familiar to the human beings. Gesture Recognition has a wide area of application including human machine interaction, sign language, immersive game technology etc. By keeping in mind the similarities of human hand shape with four fingers and one thumb, this paper aims to present a real time system for hand gesture recognition on the basis of detection of some meaningful shape based features like orientation, centre of mass (centroid), status of fingers, thumb in terms of raised or folded fingers of hand and their respective location in image. The approach introduced in this paper is totally depending on the shape parameters of the hand gesture. It does not consider any other mean of hand gesture recognition like skin color, texture because these image based features are extremely variant to different light conditions and other influences. To implement this approach we have utilized a simple web cam which is working on 20 fps with 7 mega pixel intensity. On having the input sequence of images through web cam it uses some pre-processing steps for removal of background noise and employs K-means clustering for segmenting the hand object from rest of the background, so that only segmented significant cluster or hand object is to be processed in order to calculate shape based features. This simple shape based approach to hand gesture recognition can identify around 45 different gestures on the bases of 5 bit binary string resulted as the output of this algorithm. This proposed implemented algorithm has been tested over 450 images and it gives approximate recognition rate of 94%. © 2012 IEEE.

SYNCHRONISER will boost the impact of the EU-India research policy dialogue in ICT using Foresight techniques. A COMMITTEE of stakeholders from both regions will identify research paths for joint research priorities noted at the EU-India March 2009 Information Societies Joint Working Group. SYNCHRONISER addresses 2 objectives feeding the EU-India policy dialogue and strengthens the international dimension of their ICT research programme: i) matching EU-India co-funding opportunities; ii) long term Indian research perspectives aligned with EU priorities. A Foresight exercise will identify future R&D trends to influence EU-India R&D policy. Input will include a comprehensive survey of best-in-class researchers across India using Delphi research techniques as a keynote activity resulting in publication of a Trend Study and Roadmap Report at the end of the Foresight process. This Study will act as an encyclopaedia for future EU-India joint research initiatives by highlighting current joint research scenarios and long-term perspectives. The SYNCHRONISER Consortium is well-balanced and geographically well-distributed, Indo-European, public-private-partnership with in-depth knowledge of the ICT sector in both regions and is part of a broad international network of public and private organizations, research centres and universities. The Consortium will benefit from its partners vast experience in EU-India Horizontal Support Action projects and strong support by the Government of Indias Department of Information Technology to establish synergies with other policy dialogue initiatives (e.g. INCO-NETS, BILATS, and other EU-India ICT projects). The GoI DIT will also assist in organizing high-level events involving policy-makers. SYNCHRONISER will ensure project dissemination through events, a project website, etc. The project target groups include ICT communities, policy-makers and other stakeholders from both regions

The EU-INCOOP project objective is to stimulate cooperation in the computing technologies between Europe and India, in order to support Europes leading position in computing system, while ensuring mutual benefits for both Europe and India.\nThe project intends to take a consensus building approach by bringing together researchers and stakeholders from both regions under a common forum for discussing and analysing research agendas in computing systems.\nThrough the sequence of structured workshops, channels of communication will be established between the provider constituency, and the research community. The proposed work of EU-INCOOP is designed specifically to contribute to the coordination of ICT R&D related to international cooperation in computing systems. Our goals are: The coordination of the Computing Systems community within current projects in Europe and India, by providing a forum for the exchange of best practices, ideas and issues, as well as getting regional information for the collaborative research agenda development access to and visibility of requirements and perspectives opportunities to adjust and adapt to meet the international cooperation The development of Computing Systems roadmap for Europe and India, by providing:\ta channel for articulating the musts, needs and wants of the community: the positives and negatives - what is required and what is to be avoided, what are the priorities an interpretation or mapping into functional and technical requirements a feedback channel to the stakeholder community, and debating the impacts benefits and penalties, gains and costs, simplifications and complications
