QoS Architecture in Wireless Sensor Network
Ren Feng · Chinese Journal of Computers · 2009
As a complex network consisting of sensing,processing and communication,wireless sensor network is driven by various applications and highly requires new QoS(Quality of Service) guarantees.However,unlike traditional Internet,its unique characteristics have brought unprecedented challenges in the area of QoS research.First a hierarchical description(user level,network level and node level) and a comprehensive specification for QoS parameters are presented in this paper.Then the mapping relationship between QoS parameters is carefully analyzed.Finally,a hierarchical QoS architecture is proposed for systemic QoS support in wireless sensor networks.
