During the last decade, exponential growth of mobile devices and wireless services created a huge demand for radio frequency-based technologies. Meanwhile, lighting industry has been revolutionized due to popularization LED light bulbs, which are more economical efficient. In that context, visible communication (VLC) is disruptive technology based on LEDs offers free spectrum high data rate, can potentially serve as complementary current frequency standards. this paper, we present...
Wireless sensor networks are of compact microsensors with wireless communication capability. These small devices relatively cheap the potential to be disseminated in large quantities. Emerging applications data gathering range from environmental military. As autonomous they can provide pervasive distributed and collaborative network computer nodes. Architectural challenges posed for designers such as computational power, energy consumption, sources, channels sensing capabilities. Embedded...
Most sensor network research and software design has been guided by an architectural principle that permits multi-node data fusion on small-form-factor, resource-poor nodes, or motes. We argue this leads to fragile unmanageable systems explore alternative. The Tenet architecture is motivated the observation future large-scale deployments will be tiered, consisting of motes in lower tier masters, relatively unconstrained 32-bit platform upper tier. Masters provide increased capacity....
Current implementations of Internet systems are very hard to be upgraded. The ossification existing standards restricts the development more advanced communication systems. New research initiatives, such as virtualization, software-defined radios, and networks, allow flexibility for networks. However, until now, those initiatives have been developed individually. We advocate that convergence these overlying complementary technologies can expand amount programmability on network support...

QCA promising nanoscale technology where components have nano size, ultra-low power consumption and could clock rate on terahertz range. In bottom-up approach, we first describe building blocks that compose NanoRouter such crossbar, demux parallel-to-serial converter then full architecture. demonstrate...
Most sensor network research and software design has been guided by an architectural principle that permits multinode data fusion on small-form-factor, resource-poor nodes, or motes . While we were among the earliest promoters of this approach, through experience found leads to fragile unmanageable systems explore alternative. The Tenet architecture is motivated observation future large-scale deployments will be tiered , consisting in lower tier masters relatively unconstrained 32-bit...
We present a serial communication system implemented as quantum-dot cellular automata (QCA). QCA is promising alternative to the current CMOS technology. It can be at nanoscale, reaching ultra-low power consumption and high clock rate. Communication systems are important in computer it expected even more near future. Although has been widely studied development of logic circuits, there few studies applying this technology design systems. In bottom-up approach, we describe parallel-to-serial...
Wireless Networks have become ubiquitous and dense to support the growing demand from mobile users. To improve performance of these networks, new approaches are required, such as context service aware control algorithms, which not possible on today's closed proprietary WLAN controllers. In this work, we propose Ethanol, a software-defined networking architecture for 802.11 WLANs.

A wireless sensor network is a special kind of ad-hoc with distributed sensing and processing capability that can be used in wide range applications, such as environmental monitoring, industrial applications precision agriculture. Despite their potential networks have particular features imposed by resource restrictions, low computational power, reduced bandwidth specially limited power source. In case high density nodes, some problems may arise the intersection area, redundant data,...
This paper describes a Content Addressable Memory (CAM) architecture and its ternary variant called Ternary (TCAM) using the Quantum-dot Cellular Automata (QCA). QCA is an alternative to current integrated circuit (CMOS) paradigm based on characteristics of confinement mutual repulsion between electrons.

Underwater wireless acoustic networks (UWANs) take advantage of communication to enable many distinct applications. The peculiar features underwater channels, such as long propagation delay, high bit error rates, and severely limited bandwidth, make the use medium access control (MAC) solutions designed for terrestrial radio inefficient in UWANs. This paper proposes UW-SEEDEX, a MAC protocol UWANs that employs random time slot schedules, created from seeds, avoid collisions. After exchanging...
In this work, we propose eXtend Collection Tree Protocol (XCTP), a routing protocol that is an extension of the (CTP). CTP de-facto standard collection for Wireless Sensor Network (WSN). creates tree to transfer data from one or more sensors root (sink) node. But, does not create reverse path between node and sensor nodes. This important, example, feedback commands acknowledgment packets. XCTP enables communication in both ways: root. accomplishes task by exploring control plane requires low...
