An adaptive fairness control model in wireless sensor networks
Beijing(2009)
摘要
Transmitting data to base station is the important task in wireless sensor network. Fairness control aims at sharing the equal bandwidth of all of data source node. Different event has the different priority in the wireless sensor network. The expectation reliability of event represents the priority of the event in this paper. An adaptive fairness definition is proposed based on credit and expectation reliability, and than, an adaptive fairness control model (AFC) is proposed. Furthermore, an interferer aware fair rate allocation method is proposed in AFC to allocate bandwidth among all upstream neighbors. Simulation results show that AFC can achieve fairness based on the credit of data sources and the expectation reliability of event, and the expectation reliability of the different event is ensured adaptively. © 2009 IEEE.
