An Agent Based QoS Management Mechanism in Wireless Sensor Networks

In this paper,we develop an energy-efficient QoS mechanism for wireless sensor networks using a agent-based model. In this model,agent is used for information collecting and QoS reservation at sensor nodes and executing QoS negotiation and renegotiation when network environment changes.Compared to traditional QoS Mechanisms,the agent based model will support applications to the greatest extent,and the lifetime of network is prolonged at the same time.
