For the past ten years, heterogeneous networks wired and wireless had tended to integrate seamlessly, offering effective and reliable service for medical operations. One of the problems encountered by network practitioners is the... more
The IEEE 802.11ai is an upcoming fast initial link setup (FILS) amendment that could enable a STA to achieve secure link setup in less than 100 ms. A successful link setup process will then allow the STA to send IP traffic with a valid IP... more
Many corporations are seriously concerned about security of networks and therefore, their network supervisors are still reluctant to install WLANs. In this regards, the IEEE802.11i standard was developed to address the security problems,... more
La démocratisation des réseaux Wi-Fi a grandement simplifié le déploiement des infrastructures domestiques et professionnelles. Même si cette évolution est extrêmement positive, gardons-nous de penser que cette technologie est exempte de... more
The IEEE 802.11ac is an emerging very high throughput (VHT) WLAN standard that could achieve PHY data rates of close to 7 Gbps for the 5 GHz band. In this paper, we introduce the key mandatory and optional PHY features, as well as the MAC... more
Wireless local area network (WLAN) has been widely used in many sectors. The popularity gained is due to many reasons, such as ease of installation, installation flexibility, mobility, reduced cost-of-ownership, and scalability. However,... more
An E-shaped printed monopole antenna with loaded resonant elements suitable for penta-band multi-input multi-output (MIMO) application is proposed. The simple E-shaped monopole antenna results in a single resonance, and by loading the... more
Voice over IP is a major trend in applications for wireless networks, but even so it is not immune to the risks usually related with IP networks. Proposed solutions for VoIP security are already in the market, but these solutions must... more

This paper presents the design of a compact circular microstrip patch antenna for WLAN applications which covers the band 5.15 to 5.825 GHz. The antenna is designed using 1.4mm thick FR-4 (lossy)substrate with relative permittivity 4.4... more
Abstract: The main objective is to discuss the security features and weakness of IEEE 802.15, IEEE802.11 and IEEE802.16 i.e. Wireless PAN, Wireless LAN and Wireless WAN networks. Bluetooth, Wi-Fi and Wi-Max are the three most widely used... more
The WLAN is operated in some high traffic area where the radiation beam produced by the antenna is to be utilized with optimum efficiency. The aim of those antennas is to produce some directive and switched beams rather than producing... more
The worldwide introduction of third generation mobile phone networks, coupled with advanced handsets capable of hosting rich client applications, provides a new context for mass access information systems. This infrastructure provides the... more
Handover means transferring an on going call or data sessions one cell to another. Vertical handover may be referred to a process of transferring call connected to a network/data session from one channel connected in a cell to the core... more
Networks are prone to security attacks, and wireless infrastructure network is more vulnerable. The number of people preferring Wireless networks compared to the wired network has seen an expansion of user base owing to the fast and easy... more
