Design and implementation of controller for a sensor network protocol

This paper presents the design and implementation of network controller which based on the Data Link Layer's specification of a lightweight sensor-oriented fieldbus protocol, that is sensor network protocol. The controller is packed with AVALON standard peripheral interface. It can be treated as a normal intellectual property core in project design, so that the operation on it is simplified as reading or writing on register. The test results show that the controller meets the requirements of the specification in the frame identification, arbitration, checking and so on. A follow-up application developing basement can be found easily on this controller.
