Abstract :
As wireless local area networks (WLANs) are rapidly deployed to expand the field of wireless products in military settings, the provision of robust and efficient communication in the face of noisy environments will be mandatory. Such design needs to take into consideration the WLANs limited bandwidth and high error rates. We introduce the concept of super polling which can be implemented within the IEEE 802.11 Point Coordination Function (PCF) media access control scheme. We notice a dramatic throughput increase (up to 85%) when compared with the single poll mechanism used in IEEE 802.11 PCF. The throughput increase is measured as a function of the channel noise, the superpoll overhead per data packet and the packet size
