A Distributed Coordination Function Based on Mesh Networks
Xuefang Wang · Microelectronics & Computer · 2008
With the development of mesh network and the application of the real-time multimedia traffic,there is a need not only to interconnect each other wirelessly,but also to support QoS.In this paper,we propose a Distributed Coordination Function based Mesh network,which is based on Time Division Multiplex Access\Time Division Duplex(TDMA\TDD) technology.The channel access and data transmission take place in different time slots.The MDCF is capable of distributing bandwidth fairly for end-to-end flows and performing multi-hop delivery of real-time services under specific QoS requirements.Theoretical analysis and analog simulation show that the MDCF improves throughputs and decreases end-to-end delay as compared with IEEE 802.11 EDCA and has good QoS performance.
