Broadband Wireless Networks based on IEEE 802.16 standard are developed to extend the wired networks with more efficient deployment and lower maintenance cost. IEEE 802.16e standard is proposed to support the mobility up to 60km/h with the data transmission rate up to 2Mbps, so handover has become one of the most important factors that impact the performance of IEEE 802.16e system. In order to ...

The developing IEEE 802.22 standard will allow broadband access to be provided in sparsely populated areas by using cognitive radio techniques with operations on a non-interfering basis over television broadcast bands. Such non-interfering basis operation will increase the efficiency of utilisation of that spectrum, and provide large economic and societal benefits. However, the security mechani...

Paper proposes a new design and a simulation model for the pico base station based on IEEE 802.16e standard and evaluates its performance in a mutihop-relay and mesh networks. The proposed base station design allows multihoprelay communications and thus opens a possibility for the proposed base station to be an element of mesh networks. The conventional IEEE 802.16e base stations interconnected...

With the increased use of IEEE 802.11b wireless networks, there is a strong need to support diverse Quality of Service (QoS) requirements. Recent standardization efforts are being pursued in IEEE 802.11e to introduce a framework for QoS enhancements to the IEEE 802.11b standard. Although IEEE 802.11e provides a level of service differentiation by statically associating different QoS parameters ...

This is an annotated bibliography of papers, reports and books pertaining to ANSI/IEEE Std 1471 (now also published as international standard ISO/IEC 42010). It was originally prepared for ISO/IEC JTC 1/SC 7 WG 42, the Architecture working group of the Systems and Software Engineering Subcommittee of ISO. WG 42 is the body performing the joint ISO and IEEE revision of IEEE 1471 as ISO/IEC 42010...

Wireless LAN (WLAN) is set of protocols defined by the Institute of Electrical and Electronics Engineers in the IEEE 802.11 standard[2]. This standard is itself made up of a number of substandards, allowing different speeds and technologies. Overall, most of the sub-standards of IEEE 802.11, including WLAN, use the same systems for security with only the latest revisions having any substantial ...

The purpose of my project is to design & simulate the frequency divider using ADS software. My project is totally emphasized on the IEEE 802.11 a standard. The IEEE 802.11a describes the WLAN standard. The basis of the project is the SCL (Source Coupled Logic). This thesis organization provides an overview of the evolution of digitally programmable FREQUENCY DIVIDER using CMOS technology.

This document describes the transmission of IPv4 over Ethernet, as well as IPv6 over Ethernet, in an access network deploying the IEEE 802.16 cellular radio transmission technology. The Ethernet on top of IEEE 802.16 is realized by bridging connections that IEEE 802.16 provides between a base station and its associated subscriber stations. Due to the resource constraints of radio transmission s...

–IEEE 802.1AE and IEEE 802.1AF are two IEEE 802.1X standards providing security to the data link layer. The IEEE 802.1AE is the IEEE MAC Security standard (also known as MACSec), it defines data confidentiality and integrity for media access independent protocols but lacks in providing key management and the establishment of secure associations. IEEE 802.1AF MACSec Key Agreement will facilitate...

With the ever-increasing range of video and audio applications in portable handheld devices, demand for high throughput in Wi-Fi networks is escalating. In this paper we introduce several novel features defined in next generation WLAN, termed as IEEE 802.11ax standard, and compare between the maximum throughputs received in IEEE 802.11ax and IEEE 802.11ac in a scenario where the AP continuously...
