The　emergence　of　Wireless　Mesh　Network　(WMN)　have　been　considered　as　a　promising　technology　for　their　self-configuring,　self-optimizing　and　self-healing　capabilities.　However,　the　power　limited　character　may　incur　some　nodes　become　to　selfish　nodes　in　order　to　conserve　their　processing　power　and　limit　other＇s　use　of　their　network　bandwidth.　The　node　in　Wireless　Mesh　Networks　does　not　become　to　malicious　node　immediately　while　some　nodes＇　invasion　is　not　one　action　for　accomplishment,　but　a　series　of　activities.　In　this　paper,　we　propose　a　novel　time-sequence　based　trust　management　model　aiming　at　forecast　the　possibility　for　the　situation　of　Wireless　Mesh　Networks　potential　damage　based　on　sequence　of　time-related　acts.　According　to　the　trust　evaluation　result,　the　report　is　offered　to　warning　the　malicious　trendy　for　the　nodes,　and　then　the　nodes　can　take　some　measure　to　preventing　from　potential　threaten.　Our　time-sequence　based　trust　management　can　achieve　security　goal　well　in　Wireless　Mesh　Networks.　©2010　IEEE.
