英文摘要 | In this paper, we'll propose an approach to support QoS and multimedia applications in ad hocwireless network. An ad hoc network is a collection of mobile stations forming a temporarynetwork without the aid of any centralized coordinator and is different from cellular networks whichrequire fixed base stations interconnected by a wired backbone. It is useful for some specialsituations, such as battlefield communications and disaster recovery, search and rescue. The approach we provide uses CSMA/CA medium access protocol and additional reservationand control mechanisms to guarantee quality of service in ad hoc network system. The reason wechoose CSMA protocol instead of other MAC protocols is that it is used in most of currentlywireless LAN productions. Via QoS routing information and reservation scheme, network resourcesare dynamically allocated to each multimedia application. |
