An efficient polling MAC for wireless LANs

Abstract

Polling schemes are an important class of MAC protocols for Wireless LANs. A major drawback of these schemes is their inefficiency when only a small number of mobile stations have packets to transmit. In this paper we suggest a new polling TVIAC which exploits the capture phenomena and enables simultaneous polling and information packets transmissions. Simulation results show that the new TMAC overcomes the above inefficiency considerably.
