The performance evaluation of different PPM demodulation schemes employed in PPM based IR-UWB receivers designed to meet the specifications of the IEEE 802.15.6 Standard are presented. The four different PPM demodulation schemes have been investigated for the demodulation of the standard based transmitted signal specific to the PHY layer. The performance evaluation is carried out…

Implementation of NB PHY transceiver of IEEE 802.15.6 WBAN on FPGA
This paper presents the hardware implementation of 2.4 GHz Narrowband Physical Layer for Wireless Body Area Network (WBAN) based on IEEE 802.15.6-2012 standard. Major building blocks of PHY transceiver such as CRC, spreader, interleaver and scrambler were individually designed and integrated. To avoid the inherent limitation of the data transmission and to achieve higher reliability…
Energy Efficient Transmission Approach for WBAN Based on Threshold Distance
Energy efficiency is a key concern for wireless sensor nodes, especially for wireless body area network (WBAN) in which sensors operate in close vicinity to, on or even inside a human body. In this paper, we firstly present a system level energy consumption model associated with transmission distance d and transmission data rate over on-body…
Error control scheme using decomposable codes for various QoS in multiple WBAN environment
Recently, studies on medical and health monitoring systems using wireless communications have been actively conducted. In the field of health monitoring systems, Wireless Body Area Network (WBAN) is one of the key technologies and its standardization activities have also been extensively carried out. As our previous work, we proposed an optimal QoS control scheme employing…
There is a Will, There is a Way: A New Mechanism for Traffic Control Based on VTL and VANET
Traffic light is regarded as one of the most effective ways to alleviate traffic congestion and carbon emission problems. However, traditional traffic light cannot meet the challenges in traffic regulation posed by the fast growing number of vehicles and increasing complexity of road conditions. In this paper, we propose a dynamic traffic regulation method based…
VANET-cloud: a generic cloud computing model for vehicular Ad Hoc networks
Cloud computing is a network access model that aims to transparently and ubiquitously share a large number of computing resources. These are leased by a service provider to digital customers, usually through the Internet. Due to the increasing number of traffic accidents and dissatisfaction of road users in vehicular networks, the major focus of current…
Vehicle Mobility and Communication Channel Models for Realistic and Efficient Highway VANET Simulation
Developing real-time safety and nonsafety applications for vehicular ad hoc networks (VANETs) requires understanding of the dynamics of the network topology characteristics since these dynamics determine both the performance of routing protocols and the feasibility of an application over VANETs. Using various key metrics of interest, including node degree, neighbor distribution, number of clusters, and…
Enhancing Security and Privacy for Identity-based Batch Verification Scheme in VANET
Vehicular ad hoc network (VANET) can significantly improve the traffic safety and efficiency. The basic idea is to allow vehicles to send traffic information to roadside units (RSUs) or other vehicles. Vehicles have to be prevented from some attacks on their privacy and misuse of their private data. For this reason, the security and privacy…
BYOC: Bring Your Own Control a new concept to monetize SDN’s openness
Software Defined Networking (SDN) is supposed to bring flexibility, dynamicity and automation to today’s network through a logically centralized network controller. We argue that reaching SDN’s full capacities requires however the development of standardized programming capabilities on its top. In this paper we introduce “Bring Your Own Control” (BYOC) as a new concept providing a…
Dynamic restoration with GMPLS and SDN control plane in elastic optical networks [Invited]
Optical transport networks typically deploy dynamic restoration mechanisms in order to automatically recover optical connections disrupted by network failures. Elastic optical networks (EONs), currently emerging as the next-generation technology to be adopted in optical transport, introduce new challenges for traditional generic multiprotocol label-switching (GMPLS)-based restoration that may seriously impact the achievable recovery time. At the…
