摘要：
In this paper, we propose Real Time Directed Diffusion (RTDD), a real time communication protocol for directed diffusion. Using the mechanisms provided by directed diffusion, we implement a prioritized scheduling policy over diffusion. With Just a few extensions, RTDD significantly enhances (he directed diffusion protocol, allowing time critical flows to delivery more packets on time. We also propose two new scheduling policies which do not require location knowledge. We simulate RTDD in ns 2 and compare its performance to standard directed diffusion. Results show that RTDD delivers significantly more packets on time than directed diffusion alone.
