BSMR: Byzantine-Resilient Secure Multicast Routing in Multi-hop Wireless Networks

ABSTRACT

Multi-hop wireless networks rely on node cooperation to provide unicast and multicast services. The multi-hop communication offers increased coverage for such services, but also makes them more vulnerable to insider (or Byzantine) attacks coming Continue reading

A Network-Aware Distributed Membership Protocol for Collaborative Defense

ABSTRACT

To counteract current trends in network malware, distributed solutions have been developed that harness the power of collaborative end-host sensors. While these systems greatly increase the ability to defend against attack, this comes at the cost Continue reading

Bluetooth-base Worm Modeling And Simulation

ABSTRACT

Bluetooth is one of the most popular technologies in the world in the new century. Meanwhile it attracts attackers to develop new worm and malicious code attacking Bluetooth wireless network. So far the growth of mobile malicious code is very fast Continue reading

Radio/ Antenna Mounting System for Wireless Networking under Row-Crop Agriculture Conditions

ABSTRACT

Interest in and deployment of wireless monitoring systems is increasing in many diverse environments, including row-crop agricultural fields. While many studies have been undertaken to evaluate various aspects of wireless monitoring and networking, Continue reading

Comprehensive Design and Propagation Study of a Compact Dual Band Antenna for Healthcare Applications

ABSTRACT

In this paper, a dual band planar inverted F antenna (PIFA) has been investigated for cooperative on- and off-body communications. Free space and on-body performance parameters like return loss, bandwidth, radiation pattern and efficiency of this Continue reading

Efficiency Improvement of Vehicular Antenna Systems for Ubiquitous Intelligent Systems

ABSTRACT

This paper describes the design of a high-efficiency vehicular roof-mounted antenna for wireless access for vehicular environment (WAVE) communication systems used for ubiquitous intelligent systems. The main objective of the ubiquitous intelligent Continue reading

Antenna Allocation in MIMO Radar with Widely Separated Antennas for Multi-Target Detection

ABSTRACT

In this paper, we explore a new resource called multi-target diversity to optimize the performance of multiple input multiple output (MIMO) radar with widely separated antennas for detecting multiple targets. In particular, we allocate antennas of the MIMO Continue reading

Precise Calibration of a GNSS Antenna Array for Adaptive Beamforming Applications

ABSTRACT

The use of global navigation satellite system (GNSS) antenna arrays for applications such as interference counter-measure, attitude determination and signal-to-noise ratio (SNR) enhancement is attracting significant attention. However, precise antenna array Continue reading

RF-to-DC Characteristics of Direct Irradiated On-Chip Gallium Arsenide Schottky Diode and Antenna for Application in Proximity Communication System

ABSTRACT

We report the RF-to-DC characteristics of the integrated AlGaAs/GaAs Schottky diode and antenna under the direct injection and irradiation condition. The conversion efficiency up to 80 % under direct injection of 1 GHz signal to the diode was achieved. It was found Continue reading

A New Metasurface Superstrate Structure for Antenna Performance Enhancement

ABSTRACT

A new metasurface superstrate structure (MSS)-loaded dual band microstrip line-fed small patch antenna is presented in this paper. The proposed antenna was designed on a ceramic-filled bioplastic sandwich substrate with a high dielectric constant. Continue reading

A Compact Annular Ring Microstrip Antenna for WSN Applications

ABSTRACT

A compact annular ring microstrip antenna was proposed for a wireless sensor network (WSN) application in the 2.4 GHz band. In this paper the major considerations of the conformal antenna design were the compact size and the impact on Continue reading
