Love Online
Computers have changed not just the way we work but the way we love. Falling in and out of love, flirting, cheating, even having sex online have all become part of the modern way of living and loving. Yet we know very little about these new types of relationship. How is an online affair where the two people involved may never see or meet each other different from an affair in the real world? Is online sex still cheating on your partner? Why do people tell complete strangers their most intimate secrets? What are the rules of engagement? Will online affairs change the monogamous nature of romantic relationships? These are just some of the questions Professor Aaron Ben Ze'ev, distinguished writer and academic, addresses in this 2004 book, a full-length study of love online. Accessible, shocking, entertaining, enlightening, this book will change the way you look at cyberspace and love forever.

Positioning in Wireless Communications Systems
Positioning in Wireless Communications Systems explains the principal differences and similarities of wireless communications systems and navigation systems. It discusses scenarios that are critical for dedicated navigation systems such as the Global Positioning System (GPS), and which motivate the use of positioning based on terrestrial wireless communication systems. The book introduces approaches for determining parameters that are dependent on the position of the mobile terminal and also discusses iterative algorithms to estimate and track positions. Models for radio propagation and user mobility are important for performance investigations and assessments using computer simulations. Thus, channel and mobility models are explored, particularly focusing on critical navigation environments such as urban and indoor scenarios. Positioning in Wireless Communications Systems examines advanced algorithms such as hybrid data fusion of satellite navigation, and positioning with wireless communications and cooperative positioning among mobile terminals. The performance of the discussed positioning techniques are explored on the basis of already existing and operable terrestrial wireless communication systems such as GSM, UMTS, or LTE and how positioning issues are fixed in respective standards is shown. Written by industry experts working at the cutting edge of technological development, the authors are well-placed to give an excellent viewpoint on this topic, enabling in-depth coverage of current developments.
Key features Unique in its approach to dealing with a heterogeneous system approach, different cell structures, and signal proposals for future communications systems. Covers hybrid positioning investigating how GNSS and wireless communications positioning complement each other. Applications and exploitation of positioning information are discussed to show the benefits of including this information in several parts of a wireless communications system.

An investigation of feature reduction, transferability, and generalization in AWID datasets for secure Wi-Fi networks
The widespread use of wireless networks to transfer an enormous amount of sensitive information has caused a plethora of vulnerabilities and privacy issues. The management frames, particularly authentication and association frames, are vulnerable to cyberattacks and it is a significant concern. Existing research in Wi-Fi attack detection focused on obtaining high detection accuracy while neglecting modern traffic and attack scenarios such as key reinstallation or unauthorized decryption attacks. This study proposed a novel approach using the AWID 3 dataset for cyberattack detection. The retained features were analyzed to assess their transferability, creating a lightweight and cost-effective model. A decision tree with a recursive feature elimination method was implemented for the extraction of the reduced features subset, and an additional feature wlan_radio.signal_dbm was used in combination with the extracted feature subset. Several deep learning and machine learning models were implemented, where DT and CNN achieved promising classification results. Further, feature transferability and generalizability were evaluated, and their detection performance was analyzed across different network versions where CNN outperformed other classification models. The practical implications of this research are crucial for the secure automation of wireless intrusion detection frameworks and tools in personal and enterprise paradigms.

Virtual Local Area Network Performance Improvement Using Ad Hoc Routing Protocols in a Wireless Network
Wireless Communication has become one of the most popular types of communication networks because of the many services it provides; however, it has experienced several challenges in improving network performance. VLAN (Virtual Local Area Network) is a different approach which enables a network administrator to create a logical network from a physical network. By dividing a large network into smaller networks, VLAN technology improves network efficiency, management, and security. This study includes VLAN for wireless networks with mobile nodes integration. The network protection was improved by separating the connections and grouping them in a way that prevents any party from being able to contact unauthorized stations in another party using VLAN. VLAN demonstrated restricted access to private server data by managing traffic, improving security, and reducing levels of congestion. This paper investigates the virtual local area network in a wireless network with three ad hoc routing protocols in a number of different scenarios, using the Riverbed Modeler simulation, which was used as a simulation program in this study. It was found from the investigation process that adopting VLAN technology could reduce delay and data of the network and considerably lower throughput, which is a major drawback of VLAN. Ad hoc routing algorithms, including AODV (Ad Hoc On-Demand Distance Vector), DSR (Dynamic Source Routing), and OLSR (Optimized Link State Routing) routing protocols, were used to improve the delay and throughput of the network. Routing methods with VLAN were tested across the WLAN to obtain the best throughput gain performance. The findings also revealed that these ad hoc routing protocols improved the Wireless Sensor Network performance as an additional investigation for the improvement of any network’s delay and throughput.

TCP BBR-n interplay with modern AQM in Wireless-N/AC networks: Quest for the golden pair
Effective congestion control on the internet has been a problem since its inception. Transmission Control Protocol (TCP), being the most widely used transport layer protocol tries to mitigate it using a variety of congestion control algorithms. Cubic, Reno, and Bottleneck Bandwidth and Round-trip propagation time (BBR) are the most deployed congestion controls. BBR v2 is leading the congestion control race with its superior performance in terms of better throughput and lower latency. Furthermore, Active Queue Management (AQM) algorithms try to mitigate the congestion control at the network layer through active buffer control to avoid bufferbloat. The most efficient congestion control occurs when TCP and AQM work together. Indeed, it is the TCP-AQM algorithm “ Golden pair ” that can result in the most efficient performance. This paper proposes such a novel pair based on our previously tested and published BBR-n (BBR new) with the most effective of the modern AQMs, that completely gels together to provide lower latency in wireless networks based on Wireless N/AC. Real-time experiments were performed using Flent on our physical testbed with BBR-n and modern AQMs such as Fair Queuing (FQ), Constrained Delay (CoDel), Proportional Integral controller Enhanced (PIE), Common Applications Kept Enhanced (Cake) and Flow Queuing Controlled Delay (FQ_CoDel). Various tests done on our physical testbed helped us identify CAKE as the most optimum AQM that fits with our proposed BBR-n while providing optimum throughput and lower latency in 802.11N/AC-based wireless networks.
