This Time I will tell something about the Mobile Sink Application to Wireless Sensor network. there are three research fields about the mobile sink, random path of mobile sink, path-constrained of mobile sink, and the last is path-controlled of mobile sink. the three resolving method to mobile sink can be described in the below graph.
最近在装系统时发现EFI 下面有很多设备，如下所示： fs0 : Acpi(HWP0002,PNP0A03,0)/Pci(3|0)/Scsi(Pun6,Lun0)/HD(Part1,Sig2BF15A80- 1DD2-1000-A9EF-001279B35D81) 大家能讲讲，是什么含义吗？比如：PNP0A03,0代表什么；Pci(3|0)代表什么？等等。 谢谢！

-------------------------------------------------------------- #开始装SNMP # 如果下一步的安装 net-snmp 编译出错，可能是因为得先安装这个beecrypt-devel #Installing: # beecrypt-devel x86_64 3.1.0-6 base 369 k yum install beecrypt-devel 为什么要先用YUM装这些，因为有些复杂的引用关系，全部源代码安装的话，找源文件太麻烦了。直接让YUM帮忙搞定这些引用关系吧。最后再使用源码...
