| Abstract: | Directed diffusion routing protocol of wireless sensor networks is described.An improved routing protocol based on directed diffusion is presented,which is named as IDD.By controlling diffusion of exploratory messages and making use of cost function,the energy consumption can be more efficient in free space model.Theoretical analysis and simulation results indicate that IDD achieves energy saving compared to prior method and the lifetime of wireless sensor networks is prolonged. |

| Keywords: | wireless sensor networks directed diffusion free space energy consumption simulation |
