| Abstract: | Why the ordinary net driver of 802.11x can not be used in multi-hop network is discussed in this paper,the driver model of USB wireless network card is also provided in Linux.According to the network driver model and taking Rt73 as example,the receiving interrupt function is redesigned and the test results are also given in this paper,which is tested in embedded ARM platform.The test result indicates that the nodes using the new network care driver can communication with each other before the data link buil... |
