连通性是无线网络的基本特性,CSMA网络的连通性是当下比较热门的问题之一。在SINR模型下,接收信号的强度随着发送端的距离增大而衰减,其由路径损耗指数α决定。因此,在一维和二维CSMA网络中,我们利用染色的方法,当载波侦听的范围大于或等于边颜色的数目时,构成的强连通图即可保证CSMA网络的连通。
Connectivity is the basic characteristics of wireless networks, CSMA network connectivity is one of the hot issues. Under the SINR model, the strength of the received signal decays as the distance from the sender increases, which is determined by the path loss index α. Therefore, in the one-dimensional and two-dimensional CSMA networks, we use the stained method to ensure the connectivity of the CSMA network when the carrier sensing range is greater than or equal to the number of edge colors.
