Wireless Networks Project: AODV Routing Protocol Implementation and Analysis

This project focuses on the implementation and evaluation of the AODV routing protocol within a wireless network based on IEEE 802.15.4 standards. It involves creating a chatroom system where multiple users can connect, using a star topology with dynamic node joining. The routing behavior is demonstrated through RREP, RREQ, and RERR messages, along with routing table management. Experiments analyze transmission range, power, and their effects on network reliability. The project culminates in a formal report detailing network formation procedures, routing discovery, and data analyses.

  2. Subject • Network communication • 聊天室 • Routing protocol • AODV • RREP, RREQ, RERR • ZRP • DSR • 802.15.4 network • Beacon enable network • Experiment

  3. 聊天室 • Connection • Muti-user • Username set by hyper-terminal • Communication • Using hyper-terminal to talk to each other • Scenario • One node for server • Others are clients • Every message must route to server and than send to clients • Yell, msg, who, name, …, etc • Star topology

  4. Routing Protocol • Implement a AODV-like routing protocol • at least support RREP, RREQ, RERR, Routing Table • Scenario • Each node can dynamically join the networks • Each node has a pre-assigned id • Each routing must fit with AODV standard • Requirement • Try to display the routing discovery procedure • Show the routing path • Show the routing table

  5. A tree network based on IEEE 802.15.4 • Establish a beacon enable network based on IEEE 802.15.4 • Scenario • Implement a distributed address assignment scheme • ZigBee address assignment scheme • Must support dynamic network topology • Routing ability • Requirement • You must show the routing path • You must show each node’s address • The network formation procedure must fit with IEEE 802.15.4 standard

  6. Experiment • Transmission range and network reliability • Transmission power vs transmission range • Transmission power vs reception ratio • Transmission range vs reception ratio • Nodes number vs reception ratio • Etc… • Requirement • Experiment environment • Some data analysis • Graph • Your observation • A formal report
