STATISTTCAL PACIiET ASSIGNhIENT hIULTIPLE ACCESS FOR IVIRELESS ASYNCHRONOUS TRANSFER MODE SYSTEMS

چکیده
Statistical Packet Assignment Multiple Access (SPAMA) is proposed, based on a statistical allocation of bandwidth resources to terminals which share a slotted, framed channel. The statistical nature of the centralized slot assignment scheme allows an accurate matching of bitrate requirements for different multimedia services with a minimal amount of signalling, while maintaining a throughput of up to 93%.

Bit Error Performance for Asynchronous Ds Cdma Systems Over Multipath Rayleigh Fading Channels (RESEARCH NOTE)
In recent years, there has been considerable interest in the use of CDMA in mobile communications. Bit error rate is one of the most important parameters in the evaluation of CDMA systems. In this paper, we develop a technique to find an accurate approximation to the probability of bit error for asynchronous direct–sequence code division multiple–access (DS/CDMA) systems by modeling the multipl...
متن کاملSystems Design Of A Satellite Link Protocol
In this paper we show how it might be possible to adapt asynchronous transfer mode technology to satellite links. Asynchronous transfer mode is a high-speed protocol designed with optic ber as the intended transmission media. Several problems arise when satellite channels are used. We propose to move the error recovery and detection from one layer of the asynchronous transfer mode protocol to a...

Abstract: This paper evaluates a Virtual Connection Tree (VCT) algorithm for mobile Asynchronous Transfer Mode (ATM) handoff that offers service adaptability and efficient allocation of wired resources is applied to different multiple access techniques. This creates a more distributed system where decisions about traffic conditions in different areas can be evaluated at the Base Station (BS) le...
متن کاملSecurity Technologies and Protocols for Asynchronous Transfer Mode Networks
Asynchronous Transfer Mode (ATM) is a new data communications technology that promises to integrate voice, video, and data traffic into a common network infrastructure. In order to fully utilize ATM's ability to transfer real-time data at high rates, applications will start to access the ATM layer directly. As a result of this trend, security mechanisms at the ATM layer will be required. A numb...
متن کاملAn adaptive Protocol for Wireless Asynchronous Transfer Mode Platform Network
A quality-of-service-oriented medium access control (MAC) protocol is suggested for delivering multimedia services through a stratospheric aeronautical platform wireless communication system. The invented protocol exploits the statistical multiplexing of Asynchronous Transfer Mode (ATM) technology. Combing the reservationand contention-based access schemes in a single protocol allows the platfo...
