In this paper, we introduce a new scheme called Mutual Preamble Detection (MPD) to reduce the collision recovery time in broadband power line communication (BB-PLC) networks. Although latest BB- PLC products deliver a physical layer data rate of over 1000 Mbps, this is not efficiently translated into the medium access control (MAC) layer throughput due to several factors, including the long time intervals...
To evaluate the performance of distributed medium access control (MAC) layer of emerging ultra wideband (UWB) and 60-GHz millimeter wave (mmWave) wireless personal area networks (WPANs) based on distributed reservation protocol (DRP) of ECMA-368 and ECMA-387 standards, we provide an analytical model for the probability distribution of steady state throughput as a function of the network dimensions...
In this 15.875paper, we propose a method to achieve high data rates using a shortened orthogonal frequency division multiplexing (OFDM) frame format in the physical layer (PHY) for narrowband power line communication (NB PLC) systems. The new frame structure will combine the preamble and information in the same OFDM symbol so that the overhead from the preamble is reduced. Then we consider the optimal...
According to emergency of wireless body area network (WBAN), the IEEE802.15.6 standard was established in Feb. 2012. A physical (PHY) layer, medium access control (MAC) layer and network layer were almost decided, however a payload in every packet is varied within [0,250] bytes. Since the low influence on human body and the low transmit power are required, the received signal to noise ratio (SNR)...
Due to rapidly increasing of elderly population all over the world and quickly developing of entertainment devices, wireless body area network (WBAN) attracts attention. For both medical and non-medical applications, a reliability, high energy-efficiency and high throughput of WBAN communication are requested. The well-known cluster-based is proposed to obtain the high energy-efficiency, however the...
Simulation of the IP end-to-end communication system requires accurate models which include the layers 4 to 1 of the ISO/OSI protocol stack. Usually these models are an abstraction of the real system. In this paper we focus on the PHY layer of a G.hn [1] system over PLC and calculate its throughput with respect to the PHY layer parameters: forward error correction (FEC) block size, packet size, repetitions...
In this paper we present a wireless 60 GHz OFDM transceiver for a high-throughput GigE Vision standard compliant color CCD camera system used in machine vision applications. The OFDM transceiver provides net data rates up to 3.9 Gb/s. The medium access controller (MAC) offers the reliable GigE point-to-point cable replacement functionality with special support of an asymmetrical downlink scenario...
The IEEE 802.15.4 standard is a short range wireless technology. As a revision to this standard, IEEE 802.15.4a introduces new options for PHY (physical layer) to enable ranging. In this paper, we investigate the theoretical maximum throughput and minimum delay of the un-slotted version of 802.15.4a using CSS (Chirp Spread Spectrum) PHY. The throughput and delay limits are derived for different frequency...
