4. Federal Communications Commission FCC 25 Fragment Threshold The proposed protocol uses the frame fragmentation mechanism defined in IEEE 802 11 to achieve parallel transmissions A large data frame is fragmented into several fragments each of size equal to fragment threshold By tuning the fragment threshold value we can get varying fragment sizes The determination of an efficient fragment threshold is an important issue in this scheme If the fragment threshold is small the overlap part of the master and parallel transmissions is large This means the spatial reuse ratio of parallel transmissions is high In contrast with a large fragment threshold the overlap is small and the spatial reuse ratio is low BUY ON cablematic However high fragment threshold leads to low fragment overhead Hence there is a trade off between spatial re use and fragment overhead Fragment threshold is the maximum packet size used for fragmentation Packets larger than the size programmed in this field will be fragmented If you find that your corrupted packets or asymmetric packet reception all send packets for example You may want to try lowering your fragmentation threshold This will cause packets to be broken into smaller fragments These small fragments if corrupted can be resent faster than a larger fragment Fragmentation increases overhead so you ll want to keep this value as close to the maximum value as possible 26 RIT S Request

6. To Send Threshold The RTS threshold is the packet size at which packet transmission is governed by the RTS CTS transaction The IEEE802 11 1997 standard allows for short packets to be transmitted without RTS CTS transactions Each station can have a different RTS threshold RTS CTS is used when the data packet size exceeds the defined RTS threshold With the CSMA CA transmission mechanism the transmitting station sends out an RTS packet to the receiving station and waits for the receiving station to send back a CTS Clear to Send packet before sending the actual packet data This setting is useful for networks with many clients With many clients and a high network load there will be many more collisions By lowering the RTS threshold there may be fewer collisions and performance should improve Basically with a faster RTS threshold the system can recover from problems faster RTS packets consume valuable bandwidth however so setting this value too low will limit performance 2 Beacon Interval In addition to data frames that carry information from higher layers 802 11 includes management and control frames that support data transfer The beacon frame which is a type of management frame provides the heartbeat of a wireless LAN enabling stations to establish and maintain communications in an orderly fashion Beacon Interval represents the amount of time between beacon transmissions Before a station enters power save mode the statio
