An improved IEEE 802.11 CSMA/CA medium access mechanism ...

Definition of slot time, twice the time an electronic pulse takes to travel the maximum theoretical distance between nodes.A key parameter for half-duplex Ethernet network operation. Defined as 512 bit times for Ethernet networks operating below 1 Gbit/s, and 4096 bit times for Gigabit Ethernet. Mac802_11e | startTimer(long delay, byte mode) Initiate a… implements MacInterface.Mac802_11. Implementation of IEEE 802_11b. Please refer to the standards document. For consistency, many of the variable names, constants and equations are taken directly from the specification.Air propagation delay. See Also: Constant Field Values. SLOT_TIME. GATE2005-IT-27 - GATE Overflow 802.11 is wireless LAN in which we can not detect collision so we just try to avoid collision by using CSMA/CA (carrier sense multiplesome info about "contention slot". Contention Protocols resolve a collision after it occurs.These Protocols execute a collision resolution protocol after each collision. Access Delay Analysis of IEEE 802.11 DCF I. INTRODUCTION IEEE 802.11 [1] is the most popular standard used in Wireless Local Area Networks (WLANs).Prior research has attempted to build an accurate access delay model for 802.11 DCF. However, the hidden station effect on the backoff scheme has not been given adequate attention.
