摘要/Abstract

摘要： 为了满足资源受限的无线传感器网络对于高带宽的需求，提出了一种基于信道可靠性的多信道媒体访问控制(MAC)协议RBMAC.引入了一种新的控制包结构和数据信道协商机制，提出了可发送信道列表和可接收信道列表的概念.为了从候选信道中选择最可靠的数据信道，将信道的可靠性问题抽象为博弈论中的多臂匪徒问题，并采用上限信心算法进行求解.仿真结果表明，与已有的动态信道分配方案相比，RBMAC协议的时延、吞吐量和丢包率等性能指标均有所提高，且其抗干扰能力更强.

Abstract: In order to meet the demand of high bandwidth in resource-constrained sensor networks, a channel-reliability based multi-channel MAC protocol namely RB-MAC was proposed. This protocol introduces a new kind of control packet format and handshaking process. Moreover, a ready-to-send channel list concept and a ready-to-receive channel list concept were proposed. In order to find the most reliable channel for data transmission, the data channel selection problem is transformed into the multiarmed bandit problem which is solved by the upper confidence bound algorithm. The simulation results show that, compared with dynamic channel allocation MAC (DCA-MAC), RBMAC decreases the delay and packet loss ratio, thereby increase the throughput. Besides, RB-MAC is more immune to interferences.

Key words: wireless sensor networks, multichannel media access control (MAC), control channel, channel reliability
