In this paper,we revisit the problem of target detection in wireless sensor networks (WSNs).Because that the practical environment of WSNs is very complex,a
Sleep scheduling mechanism is used in the tradition sensor network to conserve battery power.However,in cognitive radio sensor networks (CRSNs),the sleep sc
IEEE 802.11 wireless local area networks (WLANs) standard is now used widely in daily life.IEEE 802.1 le,as a new standard of WLAN,can support different ser
