Multimedia applications and real time communications like audio, voice, and video over IEEE 802.11 WLANs requires quality of service (QoS). IEEE 802.11 does not have an in-built QoS supported MAC protocol. Existing work provides service differentiation based on contention window separation (CWS) or variation of the waiting time using Inter Frame Space (IFS). In CWS, the higher priority traffic receives...
This paper presents a medium access protocol for spread spectrum networks. We have focus on the use of the protocol in MANETs to increase the throughput of the network. We focus on the use of the protocol in mobile ad-hoc networks (MANETs) to increase the throughput of the network. The existing IEEE 802.11 MAC protocol uses spread spectrum technique at the physical layer. However, it uses the same...
As wireless local area networks (WLAN) become ubiquitous and an integral part of data networks, they will also be increasingly used for applications ranging from standard Internet services like ftp to time bound multimedia applications, such as Voice (or Video) over IP (VoIP/VIP), HDTV etc. with strict latency, throughput or jitter restrictions. These applications on WLAN will also be more bandwidth...
