Abstract：

In　this　paper,　an　energy-efficient,　distance-aware　and　QoS-guaranteed　multi-path　routing　(EDQMR)　protocol　for　WVSNs　is　proposed.　The　routing　selecting　and　updating　algorithm　is　designed　under　comprehensive　consideration　of　the　hop　count,　delay,　the　distance　between　hops　and　energy　information.　The　path　of　the　largest　minimum　residual　node　energy　is　used　as　an　alternate　path　to　increase　the　network　stability.　The　path　has　gone　through　preemptive　judgments.　Before　the　node　energy　is　running　out,　the　alternate　path　is　utilized　for　transmission　in　advance.　Network　simulation　result　shows　that　the　proposed　EDQMR　protocol　is　superior　to　AOMDV　protocol　in　performance.　The　packets　delivery　ratio　has　been　improved　and　the　system　lifetime　is　prolonged　at　the　premise　of　meeting　the　requirements　of　delay.　©　2011　IEEE.
