| Abstract: | In order to improve the performances of wireless sensor networks based on directed diffusion, the simulation for network behavior was completed. The models of node distribution, directed diffusion gradient field, data aggregation and statistical characteristics were given. In addition, the main simulation algorithms and the simulation results in graphical way were presented. The theoretic analysis and simulation results illustrated that there were still defects within the original directed diffusion protocols in wireless sensor networks, and the improvement direction was indicated. |
