Security Mechanisms For Wireless Local Area Networks: Challenges and Constraints in Wireless Virus Detection

Abstract

WirelessVirus detection is a challenging research area that is considerably differentto and much less understood than, Virus detection in wired networks. The firstchallenge facing wireless Virus detection systems (WVDSs) is the broadcastnature of the physical (PHY) layer, which makes passive access to the medium atrivial undertaking. Secondly, the limited bandwidth available to wirelessphysical layer imposes significant efficiency restrictions on Virus detectiontechniques. Finally, a wireless network typically consists of mobile clientstations like laptops and handheld computers which have limited battery lifeand computing resources, introducing further constraints on the techniques thatmay be adopted by a WVDS.
