This paper presents a technique for real time human hand gesture recognition system for automatic tap operation. Hand gesture recognition based machines have been widely developed in recent years. Most of the techniques use skin color models due to its robustness and simplicity. In this work there are two major steps for achieving this goal:…

With mobile video increasingly becoming an important driver of mobile device usage, the battery consumption of mobile devices will be dominated by video delivery and playback . In this paper, we develop battery efficient video download techniques that vary video download rate dynamically, including stopping video download at times, depending on mobile device buffer levels…

In this paper planar circular Electromagnetic Band Gap (EBG) structures have been implemented in the Butler matrix fed antenna array system to improve the radiation performance of the system. Initially a conventional 4×4 Butler matrix fed antenna array system has been designed at 14.5 GHz. Asymmetricity in the gain values of major beams of the…

We propose a distributed control scheme utilizing spectral fragmentation-aware RMSA and flexible active/passive reservation mechanism for dynamic multi-domain software-defined elastic opticalnetworks. Our proposed scheme offers significant blocking probability reduction compared to conventional GMPLS/PCE architecture.

The primary task of Cognitive Radio (CR) technology is to sense the underutilized radio spectrum and to allocate it to the secondary users dynamically without any harmful interferences to primary users of the licensed band either in frequency domain or in time domain. Multitaper Method is one of the most efficient nonparametric spectral assessment techniques which provide an accurate, effectual…

In the current study of cognitive relay networks, most related works focus on the effect of interference from secondary users (SUs) to primary receivers (PRs), while neglecting the links from primary transmitters (PTs) to SUs. In this paper, the interference both from SUs to PRs and from PTs to SUs is considered in the analysis…

Cognitive Radio (CR) is very essential in day-to-day life as there is a growing demand for usage of frequency spectrum for different wireless applications. Being an opportunistic communication scenario,cognitive radio performance analysis attains prime significance. Performance analysis of a cognitiveradio scenario in a wireless channel is done by a well-known performance metric Bit Error Rate…

In this paper, we investigate the problem of incorporating full-duplex (FD) transmission in cognitivefemtocell networks (CFN) to achieve higher spectrum utilization. We aim to maximize the sum rate of a full-duplex cognitive femtocell network (FDCFN) as well as guaranteeing the quality of service (QoS) of users in the form of a required signal to interference…

Secure neighbor discovery is fundamental to mobile ad hoc networks (MANETs) deployed in hostile environments and refers to the process in which two neighboring nodes exchange messages to discover and authenticate each other. It is vulnerable to the jamming attack in which the adversary intentionally transmits radio signals to prevent neighboring nodes from exchanging messages.…

Recently, the smart grid is expected to modernize the current electricity grid by commencing a new set of technologies and services that make the electricity networks secure, automated controlled, cooperative and sustainable. Consequently, the smart control centre feels the requirement of a robust and scalable technique for state estimation (SE) that allows continuous and accurate…
