| Abstract | Cyber-Physical Networked Systems (CPNS) are systems that integrate a multitude of nodes that perform computations for the sake of interacting with, or controlling, a physical process. The network plays an important role in CPNS supporting the interactions among the distributed nodes that enable the collaborative work towards the application goals. Some systems, e.g., target tracking systems, require reconciling properties that are strongly influenced by the network in opposing directions. For example, it is important to maintain low energy consumption to prolong lifetime but it is also important to be reactive to event propagation for quick target detection. In the ZigBee/IEEE802.15.4 standards, the beacon-enabled mode can achieve low energy consumption by adopting low duty cycles but this causes reaction latency to events to degrade. In this paper, we carry out several experiments that validate the potential of the recently proposed dual-rate beacon scheduling method for ZigBee/IEEE802.15.4 sensor networks to accomplish a trade-off between low energy consumption and rapid events propagation. The experiments include both simulation with OPNET as well as a real test-bed built on CC2430-based nodes. The results show the impact of relevant configuration parameters and the superiority of the dual-rate beacon scheduling in providing low energy consumption and low latency in CPNS. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
