Development and Prospect on QoS Routing Protocols in Wireless Ad Hoc Networks
无线Ad Hoc网络QoS路由协议研究的进展与展望

Wireless ad hoc networks arc multi-hop and distributed. In a wireless ad hoc network, there is no stationary infrastructure, and the node acting as terminal and router can move freely. The application environments and connecting with the Internet require that wireless ad hoc networks should support Quality-of-Service (QoS). QoS routing is the key to support QoS in wireless ad hoc networks. This paper comprehensively summarizes and deeply analyzes the researches of recent years on QoS routing. Based on this analysis,we deeply discuss the problems that must be resolved to implement QoS routing in wireless ad hoc net works, and give some advice to the research in the future.
