摘要：

An application scenario embracing the area of Intelligent Transportation Systems (ITS) is studied in this paper. The infrastructure of the application scenario is wireless sensor networks with mobile sinks. The WSN is query-based and with multi-hop transmission for data sensing. The application-specific network architecture was introduced and exploited. The detailed routing algorithm as well as its initialization phase were developed. Analysis was given on the end-to-end delivery latency, aiming to optimize the routing in both real-time ability and energy efficiency. Compared with the existing routing mechanism for the same application scenario, the proposed algorithm demonstrates less delivery latency and consequently lower energy consumption. Extensive simulations were conducted to evaluate the performance of the routing mechanism as well as to compare it with existing method numerically.
