Communication and networking research introduces new protocols and standards with an increasing number of researchers relying on real experiments rather than simulations to evaluate the performance of their new protocols. A number of testbeds are currently available for this purpose and a growing number of users are requesting access to those testbeds. This motivates the need for better utilization...
Industrial Wireless Sensor Networks (IWSN) are preferred over bulky wired networks in industrial monitoring and automation. These sensors are used to access locations, which are technically unreachable. The use of IWSN not only reduced the cost of automation systems but also played a significant role in alarm management by real time data transfer. ZigBee and WirelessHART are already deployed protocols...
Within Mobile Ad-Hoc Network(MANETs) unusual categories of routing protocols have been determined. It is a group of wireless system. MANET is other susceptible to a variety of attack than wired system. Black hole attack is further meticulous intimidation to MANETs. The routing protocols of MANET is less protected and therefore consequenced the system with malicious node. There are various routing...
High smartphone penetration and Average Revenue Per User (ARPU) growth imply a quick and good broadband services delivery. In this context, Mobile Networks Operators (MNOs) have to satisfy current subscribers and gain new ones. Small Cells (SCs) are a promising alternative to MNOs to reach emerging markets and meet the rising mobile broadband demand. However, most of those competitive markets have...
A Community Network (CN) is a bottom-up network infrastructure that interconnects communities of people and represents a promising and successful networking model. The more people join a CN, the higher is the demand for a wider range of community services and the need for scalable network protocols. CN designers and passionates hence require adequate frameworks to develop and test different technical...
This paper proposes a reconfigurable and concurrent dual-band power amplifier for upcoming wireless applications such as LTE carrier aggregation. The designed power amplifier operates concurrently at 1600 MHz and 2100 MHz when the switches are OFF; whereas, when the switches are ON, the power amplifier operating frequencies shifts to 1800 MHz and 2300 MHz. Thus, the proposed power amplifier topology...
In recent years Wireless Sensor Networks (WSNs) are the most widely used networks and got attractive applications in various fields such as medical, military, safety agriculture and environmental monitorings etc. People are attracted to the networks which provide good services with less cost and judges the network based on their experience of network performance. The network performance seen by the...
Greedy routing is an appealing routing mechanism, which does not require to build and maintain routing tables. Although, it requires a specific geometric coordinate assignment for underlying network nodes. Such a coordinate assignment is called a greedy embedding, where messages are routed over a distance decreasing path from the source to the destination. Despite various research on computation of...
This paper presents a new cascaded connection of multi-output-port converter for Plug-in Hybrid Electric and On-Board Electric Vehicles, which is suitable for dynamic wireless power transfer energy storage systems such as battery, ultra-capacitor, and load. In order to acquire the system power transfer integration between output ports, the central control stability is analyzed by phase shift function...
This work demonstrates the effects of multi-layer adaptivity for a wireless live video streaming scenario. We investigate a specific type of adaptations, the so-called transitions, which switch between different network mechanisms during the runtime of an application. In comparison to a pure configuration adaptation, a transition is beneficial because a system may select those mechanisms that perform...
In this study, a novel phase controlled of single switch active rectifier (S-SAR) is investigated for applications in wireless energy transfer. The proposed rectifier structure is based on the connection of controllable single switch thorough full bridge rectifier and regulation by a phase-shifted PWM signal. Theoretical and simulation results show that the performance of the proposed active rectifier...
This paper analyses a multi-output half-wave semi-synchronous rectifier (SSR) by using a uniform field transmitter. The presented multi-output half-wave rectifier topology is achieved by replacing half-wave rectifier lower diode with a synchronous switch and regulation by a phase-shifted PWM signal. The front end transmitter is intended to generate uniform magnetic fields over the coil area. To confirm...
