Study of QoS models in MANET
移动自组网中的服务质量模型研究

Quality of Service (QoS) in Mobile Ad hoc Networks (MANET) has been one of hot topics. However, it is very difficult to realize QoS in MANET due to the mobility, processing and power ability of mobile node. This paper summarized eight kinds of QoS models in MANET networks from the point of system and software engineering, and introduced mainly the approaches and characteristics in QoS implementation. In the last section, several QoS methods were compared and analyzed in scalability, level of QoS supporting, relaying on ability of node, flexibility and security. Directions for future study were pointed out.
