Emerging of wireless sensor networks results in several modeling and design issues on the network simulations. In previous works, most researchers have used three evaluation approaches such as analysis method, computer simulation and real test-bed measurement in order to verify the performance of wireless sensor networks. Among these approaches, analysis method is widely used since the other approaches have significant drawbacks such as limitation of network power, computational problem of distribute processing and complication of debugging process. However, the analysis method also shows poor performance when it deals with complex operations in huge wireless sensor networks. Thus, in this paper, we design and develop SMAC and AODV protocols by using Ptolemy tool in order to improve the simulation performance. The developed Ptolemy actor can be easily adapted to compare and evaluate the various protocols for wireless sensor networks.
