Recent Advances in Communications and Networking Technology (Formerly Recent Patents on Telecommunication) (Discontinued) - Volume 3, Issue 1, 2014

Networks and communications are the infrastructure on which multimedia and information technologies are built. There are a vast number of networking techniques that depend on the type of multimedia and information technology applications that the network is designed to facilitate. This issue concerns recent communication technologies for transmission, compression, security, and expression of a diverse range of d Read More

Multicast communications can help to transmit traffic efficiently to target groups of interested users without extra bandwidth or power resources. However, compared to unicast transmission, multicast over wireless channels does not support reliable transmission due to limitation of the message overhead. In this paper, we study the problem of how to guarantee reliability while maintaining the maximum throughput in m Read More

Digital yarns or conductive yarns are the ones that enable data transmission. In particular, smart clothes woven by both ordinary and digital yarns are more than wears, and eventually become wearable and mobile computing devices. Emphasizing a high potentiality of such clothes, we firstly introduce digital yarn that we developed, presenting its characteristics and a way of assessing its data transmission performance. Secon Read More

We present the design, prototyping, implementation, and test of Eth2Bee for the Xbee to Ethernet gateway for wireless personal area network. It supports ZigBee, WIFI, and Bluetooth. The Eth2Bee board is very useful for configuring in low power wireless sensor networks. Eth2Bee system is a combination of two technologies: Ethernet technology based on wired LAN technology and ZigBee technology based IEEE 802.15.4 stan Read More

Physical inactivity is threatening the consistent trend of increased life expectancy that we have enjoyed over the past century. Thus, approaches to increase levels of physical activity are required. Social influence is an effective strategy for changing attitudes and behavior. An individual’s level of physical activity can be affected by interactions with his or her peer group; social interaction therefore can serve as a motivation for phy Read More

This paper presents a multiple-watermarking scheme for mobile 3D secure transmission. The proposed scheme embeds a unique watermark and a WCA (Watermark Certification Authority) watermark into the spatial and encryption domains of mobile 3D content based on the Anonymous Buyer-Seller Watermarking Protocol. The seller generates a unique watermark and embeds it into the distribution of vertex data of the 3D cont Read More

The inter-cell interference problem is a key challenge in OFDMA-based cellular networks because it significantly decreases the throughput of the users at the cell edge. Mitigating this problem requires an inter-cell interference coordination (ICIC) scheme that divides the spectrum into a power constant band and a power limited band for the cell edge users. Overall, static ICIC or frequency reuse schemes are effective when user Read More

This paper focuses on solving the problem of checking the exponential stability of a class of stochastic fuzzy cellular neural networks with Markovian jumping parameters, time-varying delays and distributed delays. By constructing suitable Lyapunov functional and applying stochastic analysis, we firstly developed some sufficient conditions to guarantee the almost surely exponential stability and the exponential stability in the mean Read More
