The two kinds of routing protocols are based on different application. The first is proposed on lossy network link state which can`t provide steady transmission. The second one is same with special geographic area that covers much obstacle. The packet can be transmitted along the appointed trajectory and make the round of the obstacle easily. Furthermore, in order to testify the capability of our work, the NS-2for validation for the function and investigation of the performance are used. The main research works and results are listed as follows:1. Implement the detailed performance analysis between existing routing protocol in wireless sensor networks.Based on sensitive degree in different application wireless sensor networks, the existing routing protocols are stapled and analyzed in detail. The routing protocols based on trajectory which are better than other protocols balance total energy of sensor networks and increase lifetime of networks through existing routing protocols of compare.
