This paper presents a novel iterative non-breakdown rectifier topology which would practically solve the rectifier's early breakdown problem in multi-sine wireless power transmission (WPT) for biomedical application. The proposed rectifier holds an iterative topology which can extend the reverse breakdown voltage limitlessly with its forward threshold voltage remains. It keeps high conversion efficiency...
Body Area Networks (BANs) are considered as the key building blocks for the emerging application of upcoming generation of networks that would be extended towards the wearable technology as well as the Internet of Things. Starting from the traditional network scenarios to today's advanced network infrastructure, BANs have played a very significant role in developing the computer network industry and...
Channel assignment is essential in wireless communications as it determines which channel to use for each pair of nodes. It has been extensively studied in literature, while all the existing works assume that the link exhibits equivalent performance for different channels and thus the objective is simply to allocate different channels to different wireless links. This assumption is however not always...
In this paper we present a simulation tool to determine the characterization of a Vehicle-to-Infrastructure radio channel at 60GHz in two scenarios: suburban and urban. A precise estimation considering the topology and the morphology of both areas is performed with the aid of in-house deterministic 3D ray launching algorithm. Estimations of received power as well as of delay parameters show the relevance...
In this paper, we study the influence of the roadmap topology and the number of vehicles when accounting for the vehicular communications capabilities, especially in urban scenarios. Additionally, we propose the use of two metrics: the SJ Ratio (SJR) and the Total Distance (TD), as the metrics that better correlate with communications performance. Hence, researchers will better characterize the different...
Wireless Sensor Network is collection of sensor nodes which consist of sensing device, storage device, processing unit and antenna. These nodes may be placed in difficult physical environment for sensing an event, collecting data, processing data and forwarding it using wireless network to the sink, where data can be stored, processed and analyzed. Animal monitoring, Building monitoring and other...

Designing high performance channel assignment schemes to harness the potential of multi-radio multi-channel deployments in wireless mesh networks (WMNs) is an active research domain. A pragmatic channel assignment approach strives to maximize network capacity by restraining the endemic interference and mitigating its adverse impact on network performance. Interference prevalent in WMNs is multi-faceted,...
Digital multiplexers 12 (DMX 512) is a standard for digital data transmission mainly to control stage lighting. Conventional DMX512 employs bus topology in a daisy chain network. The network consists of one master and one or more slave devices connected through wires. Although wired connection validates reliable data transfer, yet it increases network complexity, specifically, where wires can be prohibitively...
Vehicular Ad Hoc Networks (VANETs) have emerged as an exciting research and application area. The envisioned applications, as well as some inherent VANET characteristics such as highly dynamic topology, frequently disconnected network, and different and dynamic network density, make data dissemination a challenging task in these networks. Several approaches for data dissemination in VANETs have been...
Devices for Wireless Sensor Networks (WSN) are limited by power and thus routing protocols should be designed with this constrain in mind. WSNs are used in three dimensions (3D) scenarios such as surface of sea or lands with different level of highs. This paper presents and evaluates Three Dimensions Position Based Adaptive Real-Time Routing Protocol (3DPBARP) as a novel, real-time, position based...
Emerging on-chip communication technologies like wireless Networks-on-Chip (WiNoCs) have been proposed as candidate solutions for addressing the scalability limitations of conventional multi-hop NoC architectures.

For transmitting data in scenarios showing a high user density, infrastructure based and multihop Ad hoc communication can be combined to benefit from the reliability of a stable backbone network and the increased coverage of multihop communication. Such scenarios have been investigated from a cross layer perspective in the recent years mainly focusing on pure performance optimization. However, the...
Assuming wireless communication in scale-free networks, the local routing model can be extended with a novel approach which takes spatial information into account as well. The properties of the proposed model are analyzed in this paper also when the nodes of the network are moving along straight lines in the unit square. Furthermore, we analyze how reconfiguration affects the throughput and energy...
In this paper, we propose a novel architecture for next generation cellular networks that enables collaborative forwarding at Layer 2 among adjacent eNBs with the aid of enhanced user equipment (UE) devices, that act voluntarily as packet forwarders. Therefore, legacy UEs are leveraged as active network elements being capable of operating simultaneously over multiple base stations (eNBs). To this...
IPv6 over Low power Wireless Personal Area Networks, also known as 6LoWPAN, is becoming more and more a de facto standard for such communications for the Internet of Things, be it in the field of home and building automation, of industrial and process automation, or of smart metering and environmental monitoring. For all of these applications, scalability is a major precondition, as the complexity...
