Multimedia applications have revolutionized mobile phone usage, with emphasis on interaction between user and the phone. Camera being an integral part of new generation phones can be used to felicitate this interaction using machine vision techniques. Vision algorithms have been explored to be ported on to mobile devices, however due to real-time complexity(More)
Internet of Things (IoT) is a new paradigm which is enormously gaining ground in today's world. In order to maintain desirable service quality in the transmission of sensed data, data aggregation schemes are highly used. The main goal of data aggregation scheme is to collect and aggregate data packets in an efficient manner so as to reduce power(More)
IEEE 802.11ah is proven to be a suitable communication standard for Smart City projects. However, due to the absence of Restricted Access Window (RAW) size adjustment and proper relay node solution, it fails to optimally utilize the resources in heterogeneous networks. In this paper, we propose a method to estimate the RAW size based on traffic loads and(More)
