The growing popularity of wireless sensor network applications has stimulated strong interest in extending quality of service support to existing routing protocols. Conventional wireless sensor network routing protocols usually concentrate on the constrained condition of ‘shortest path’ with minimum used energy. However, the path with minimum used energy can’t provide the minimum end to end delay guarantee. Moreover, wireless sensor network is required to support the delay-sensitive traffic. So the reduction of the end to end delay is a new challenge for wireless sensor network. To this point, this paper mainly focuses on the node delay constrained energy efficiently routing algorithm.
