Vehicular Ad hoc NETworks (VANETs) are a promising technology that can widely apply to monitor the physical world in urban areas. Efficient data delivery is important in these networks and optimal route selection is vital to improve this factor. Vehicular mobility is a reflection of human social activity and human trajectories show a high degree ...
An optimum sensor node placement mechanism for Wireless Sensor Network (WSN) is desirable in ensuring the location of sensor nodes that offers maximum coverage and connectivity with minimum energy consumption. This paper proposes a sensor node placement algorithm that utilizes a new biologically inspired optimization algorithm that imitates the behavior of territorial predators in marking ...
A novel technique for sampling clock recovery in a wideband networking waveform of a software defined radio is proposed. Sampling clock recovery is very important in wideband networking radio operation as it directly affects the medium access adaptive time slot switching rate. The proposed sampling clock recovery algorithm consists of three stages. In the first ...
As the communication industry has connected distant corners of the globe using advances in network technology, intruders or attackers have also increased attacks on networking infrastructure commensurately. System administrators can attempt to prevent such attacks using intrusion detection tools and systems. There are many commercially available signature-based Intrusion Detection Systems (IDSs). However, most IDSs lack ...
Allocating slots dynamically to the service flows in heterogeneous wireless network is highly complex and non-linear. Since the link quality is continuously changing, a wireless network employing adaptive modulation like WiMAX, allocating slot in such network is based on the link quality. In this paper, the author’s present link aware packet scheduling algorithm using packet’s ...
Quality of Service (QoS) guarantees plays a critically important role in mobile wireless networks. For the real time services like multimedia video conference, the key QoS metric is to ensure a stringent delay-bound rather than high spectral efficiency. In this paper, a cross-layer approach is proposed to investigate the impact of physical-layer infrastructure on data-link ...
