Implementation of the Sensor-MAC Protocol for the JiST/SWANS Simulator

Wireless sensor networks consist of very large number of resource constrained nodes. Therefore, protocols and applications for wireless sensor networks need to be very scalable and efficient. To properly evaluate the performance of these networks a scalable ad-hoc wireless network simulator is needed. The JIST/SWANS is a highly scalable ad hoc wireless network simulator that has been recently developed. However, JIST/SWANS does not have an energy model or a MAC protocol for wireless sensor networks. In recent work, we developed an energy model for JiST/SWANS. This work presents our implementation of the S-MAC protocol for the JiST/SWANS simulator. The implementation is validated through simulations. Results using JiST/SWANS and NS-2 are obtained and compared for similar network scenarios.
