We　propose　a　new　routing　algorithm　for　wireless　sensor　networks　for　post-disaster　road　monitoring　in　this　paper　in　which　the　wireless　sensor　nodes　are　arranged　in　a　linear　manner.　It　thus　becomes　necessary　for　the　design　of　more　efficient　routing　algorithms　for　such　types　of　applications.　Our　new　algorithm　includes　route　establishment,　packet　forwarding　and　route　maintenance　by　considering　the　special　characteristics　of　node　placement　and　data　transmission　to　make　the　algorithm　more　effective　and　efficient　than　general-purpose　routing　protocols.　©　2011　IEEE.
