An Energy Efficient MAC Protocol for Wireless LANs
This paper presents an optimization of the power saving mechanism in the Distributed Coordination Function (DCF) in IEEE 802.11 standard. In the 802.11 power saving mode specified for DCF, time is divided into so-called beacon intervals. At the start of each beacon interval, each node in the power saving mode periodically wakes up for a duration called the ATIM Window. The nodes are required to...
متن کاملEfficient MAC strategies for the IEEE 802.11n wireless LANs
Current IEEE 802.11 wireless local area network (WLAN) standard products can provide up to 54 Mbps raw transmission rate, while non-standard WLAN products with 108 Mbps have already appeared in the market, and the next generation WLAN will provide much higher transmission rates. However, the medium access control (MAC) was designed for lower data rates, such as 1–2 Mbps, and it is not an effici...
متن کاملReliable multicast MAC protocol for wireless LANs
Reliable multicast in wireless applications is gaining importance with the development in technology. Applications like multicast file transfer, distributed computing, chat and whiteboard applications need reliability. However, due to mobility and wireless channel characteristics, obtaining reliability in data transfer is a difficult and challenging task. IEEE 802.11 does not support reliable m...
متن کاملAn Adaptive MAC Protocol for Ad-Hoc Wireless LANs
An ad-hoc Learning Automata-based protocol for wireless LANs, capable of operating efficiently under bursty traffic conditions, is introduced. According to the proposed protocol, the mobile station that is granted permission to transmit is selected by means of Learning Automata. The Learning Automaton takes into account the network feedback information in order to update the choice probability ...
متن کاملQAP: A QoS supportive adaptive polling protocol for wireless LANs
A QoS supportive Adaptive Polling (QAP) protocol for wireless LANs is introduced. QAP operates under an infrastructure wireless LAN, where an Access Point (AP) polls the wireless nodes in order to grant them permission to transmit. The polled node sends data directly to the destination node. We consider bursty traffic conditions, under which the protocol operates efficiently. The polling scheme...
