摘要:

针对无线认知传感器网络的资源有限性和频谱动态分配,提出了基于首要信道半双工的无线认知传感器网络广播协议。在没有公共信道和时钟同步的情况下,该协议通过单个收发机的收发状态转换和信道表的交换进行网络的初始化。经过网络初始化,节点由首要信道形成拓扑,节点通过首要信道以半双工数据传送方式进行广播。仿真实验表明,与完全广播相比,该协议降低了广播延迟和开销,更利于应用于无线认知传感器网络。

Abstract:

In the light of the limited resources and the dynamic pectrum distribution in the CRSN, a half duplex mul-ti-channel broadcast protocol for CRSN was proposed based on the home channel theory. In the absence of the common channel and clock synchronization, the proposed protoc initialized the network through the transitions of the sending and receiving state of the single transceiver and the nges of the channel table. After network initialization, the to-pology of nodes was formed based on home channel. Nodes broadcast through home channel based on half duplex data transfer mode. According to the simulation results, it is proved that, compared with complete broadcast, the proposed protocol effectively improves the success rate of broadcast and reduces broadcast delay and overhead, which gets better performance in practical application of CRSN.

Key words: CRSN, home channel broadcast, complete broadcast, sing e transceiver
