Optimizing Social Information by Game theory and Ant Colony Method to Enhance Routing protocol in Opportunistic Networks
Publication date: Available online 4 July 2016 Source:Perspectives in Science Author(s): Chander Prabha, Ravinder Khanna, Surender Kumar The data loss and disconnection of nodes are frequent in the opportunistic networks. The social information plays an important role in reducing the data loss because it depends on the connectivity of nodes. The appropriate selection of next hop based on social information is critical for improving the performance of routing in opportunistic networks. The frequent disconnection problem is overcome by optimizing the social information with Ant Colony Optimization method which depe...

Artificial ageing response of a Al-Mg-Si alloy - a statistical correlation
In this study, approach of design of experiment has been employed to establish the statistical correlation amongst the parameters of artificial ageing, i.e., time of ageing (tA) and temperature of ageing (TA), and the ageing response, as measured by the variation of hardness for an Al-Mg-Si alloy. The results related to the main effect of the parameters of ageing obtained via linear statistical analyses indicate that tA is more effective than the TA to achieve the higher level of hardness specifically when TA is beyond 203°C. Following a second order non-linear relationship, a 3-D correlation between tA, TA and hardness v...

Application of adaptive Savitzky-Golay filter for EEG signal processing
Publication date: Available online 4 July 2016 Source:Perspectives in Science Author(s): Deepshikha Acharya, Asha Rani, Shivangi Agarwal, Vijander Singh A Savitzky Golay filter typically requires pre-determined values of order and frame size for its fabrication. Generally, a random hit-and-trial method or prior experience is required to determine the suitable values of design parameters. However, the proposed adaptive Savitzky Golay filter aims to provide a generic framework for optimal design of filter vis-à-vis the order and frame size of the filter. The algorithm uses all the possible combinations of these ...

Optimal power and performance trade-offs for dynamic voltage scaling in power management based wireless sensor node
Publication date: Available online 5 July 2016 Source:Perspectives in Science Author(s): Anuradha Pughat, Vidushi Sharma Dynamic voltage scaling contributes to a significant amount of power saving, especially in the energy constrained wireless sensor networks (WSNs). Existing dynamic voltage scaling techniques make the system slower and ignore the event miss rate. This results in degradation of the system performance when there is non-stationary workload at input. The overhead due to transition between voltage level and discrete voltage levels are also the limitations of available dynamic voltage scaling (DVS) tech...
