We are experiencing the expanding use of location-based services such as AT&T TeleNav GPS Navigator and Intel’s Thing Finder. Existing locationbased services have collected a large amount of location data, which have great potential for statistical usage in applications like traffic flow analysis, infrastructure planning and advertisement dissemination. The key challenge is how to wisely use th...

In this paper, we identify security objectives and requirements for a class of ubiquitous computing technology, namely environmental sensing infrastructure. The method used starts with analyzing scenarios to define user-driven security objectives for specific applications and identify hints to potential misuse in a realistic setting. The described applications are examined to understand how the...

In August 2014 CSCS received a new test bed storage system from Cray, namely the latest incarnation of their innovative HPC data storage product dubbed Sonexion 2000. The purpose of this study is to evaluate this product, covering installation, configuration and tuning including the Lustre file-system and integrating it with an x86 cluster. We describe the hardware, infrastructure, software sta...

Mobile ad hoc network is a collection of multi hop wireless mobile nodes that communicates with each other without centralized control or established infrastructure. It is the network with dynamically and frequently changing topologies as each node in it moves. Due to a no. of constraints in self organizing and self operating networks, routing. It is a challenging problem. To find optimum route...

Increasing the performance of computing system today means more parallelism. Systems are becoming multi-cores. The on-chip interconnect is a complex infrastructure having a crucial impact on the system global performance and functionality. In this draft paper we present recent results and work-in-progress towards a general compositional approach for the validation and verification of networks-o...

This chapter, as a case study would like to put forward a pioneering programme of the United Nations Development Programme (UNDP) that acted as catalytic factor in many developing countries initiating from 1992. Many of projects under this programme, namely the sustainable development networking programme (SDNP) lead the country ́s information technology sector and eventually act as a positive c...

This paper describes a prototype grid infrastructure, called the “eMinerals minigrid”, for molecular simulation scientists. which is based on an integration of shared compute and data resources. We describe the key components, namely the use of Condor pools, Linux/Unix clusters with PBS and IBM’s LoadLeveller job handling tools, the use of Globus for security handling, the use of Condor-G tools...

As linguistic collection and annotation scale up and collaboration across sites increases, novel technologies are necessary to support projects. Recent events at LDC, namely the move to a web-based infrastructure, the formation of the Software Group, and our involvement in the NSF LAPPS Grid project, have converged on concerns of efficient collaboration. The underlying design of the Web, typica...

— In line with the growing interest in efficient data distribution services to large mobile user groups, 3GPP is standardizing the introduction of support for multicast services into GSM and WCDMA networks. The mobile infrastructure needs to be enhanced in the wireless and in the wireline parts to support new signaling and payload transport procedures. Also mobility , charging and radio resourc...
