碩士 === 國立交通大學 === 電信工程系 === 91 === Wireless communications are an emerging technology and are becoming an essential feature in the last few years. Not only computer networks are becoming mobile, eventually each device will have a wireless interface. Simultaneously, multimedia is having an equivalent growth from data to voice up to video communications. Some of these applications impose requirements on some communication parameters, such as bandwidths, packet drop rates and delays in order to work properly. However, the traditional networks using best effort transmission mode to deliver data cannot satisfy the service requirements for these applications due to the lack of Quality of Service guarantees. In this thesis, we provide throughput guarantee with differential service by introducing the enhanced mechanism, which is an extension of IEEE 802.11 MAC protocol. With use of enhanced mechanism, the service of control will be fully distributed and Different service will be achieved by minimizing migration effort on current standard. The performance of proposed mechanism has been evaluated by simulation. Simulation results show the mechanism will behave well in different kinds of scenarios.
