%X In this paper,a novel Differentiated Service scheduling algorithm for wireless sensor network based on Di- rected Diffusion has been introduced.The proposed scheduling scheme called Round Robin Path Scheduling(RRPS). For RT traffic,RRPS takes into consideration the hop count of a path first and then the minimum available energy a- long the path when it sets up the path between a sensor and a sink.Meanwhile,for BE traffic,RRPS puts higher pri- ority on the minimum available energy of the path compared to the hop count.Comprchensive simulation experiments show that RRPS has the following advantages:(1)differentiates dissemination service for RT and BE traffic,(2)a- chieves lower delay for RT traffic than Directed Diffusion(DD).(3)exhibits substantially longer network lifetime than DD.
