Many different applications for different challenges have been developed. In order to reduce the efforts in programming, it is necessary to develop a new programming model suitable for the wireless sensor network. In this paper, we present a sensor programming environment (SPE) for users to write application programs for wireless sensor networks. The SPE includes a middleware, for hiding low-level operations and providing high level APIs for application programs, and a role-based programming library, for abstraction of programming design. A user can build up a role graph for his/her application program based on the role-based programming model. From the role graph of an application program, a user can write codes for each role and analyze the execution flow of the application program. We have shown a design example by using the proposed SPE. The simulation results indicate that the proposed SPE is easy to use and the role-based programming model can reduce the design efforts of a WSN program.
