  1. Introduction The HSN routing stack implements two routing protocols: Destination-Sequenced Distance-Vector (DSDV) and Flood Heterogeneous Sensor Routing (HSN) Stack in TinyOS

  2. 1. DSDV a. Introduction The DSDV routing layer provides the implementation of the Destination-Sequenced Distance Vector protocol to multi-hop packetsback to a sink node. b. Functionality The implementation maintains one destination (sink node) and can be compiled

  3. with different routing metrics to calculate the cost based on different criteria. c. How to use DSDV Installation Compilation Flags

  4. 2. Flood a. introduction The Flood module implements a flood in mechanism to send packets to every node or a specific node in the network.

  5. b. Functionality The Flood module broadcasts an incoming packet to its neighborhood if the packet was not received before and the TTL is greater than 0.

  6. 3. TraceRoute TraceRoute is a module that can be wired with applications to visualize the actual route the packets take.

  7. 4. TinyDBShim a. Introduction TinyDBShim allows TinyDB to utilize the HSN routing stack. b. Functionality TinyDBShim wires TinyDB with the DSDV routing layer and Flood module.

  8. Application 1. TraceRouteTest a.Introduction This TraceRouteTest application tests the basic functionality of the traceroute, DSDV routing, and setting modules.

  9. b. Functionality In the default configuration, each mote sends back a traceroute packet to the sink node every 5 seconds along with 1 byte of piggyback information. As a packet multi-hops back to the sink node, each intermediate node along the path adds its node ID (one byte) into the traceroute payload. The sink node receives the complete traceroutemessage, adds the framing header, and sends it to the UART. If the sink node receives a packet from the UART, it forwards the packet to the radio.
