    v27 v28  
    1313 * '''Check Services''': Self-healing, Task Scheduling and Monitoring Framework.

    15 == Software Architecture ==
    16 
    17 The entire Check WSN architecture is given in the diagram below. The sensor network itself is built around [http://www.atmel.com/dyn/Products/tools_card.asp?tool_id=4291 RZRAVEN] and Sparrow nodes that form a heterogeneous multi-hop network using a modified version of Atmel's [http://sensei-dev1.grid.pub.ro:8184/rd RUM] protocol over which we ported the Binary Web Services application and our own task scheduling and monitoring apps.
    18 
    19 The gateway is an embedded ARM7 [http://www.atmel.com/dyn/resources/prod_documents/doc6195.pdf board] running a modified version of the [http://www.utasker.com/ uTasker OS]. An IPv6 layer added over the existing OS allows the SAM7X platform to act as an IPv6 Edge Router in addition to an 802.15.4 PAN Coordinator. The PAN Coordinator performs the classical functions defined in section 5.3 of the IEEE 802.15.4-2006 specification. It will start and maintain a non-beaconing network. The edge router functionality will route IPv6 network traffic to the appropriate end and router nodes based on their specific IPv6 addresses.
    20 The SAM7X provides multiple interfaces for users to interact with the 802.15.4 wireless network. Among these are RS232, USB, telnet and simple direct web interface.
