ETX Based Routing Module in
Wireless Networks
In this project we develop an ETX routing metric module using cross layer approach. It is developed as a plug-in module which can be used for routing protocols of wireless networks.
Objective
- Efficient calculation of the link loss ratios between nodes.
- Calculate the ETX metric with all categories of routing protocols i.e. both reactive and proactive routing protocols in wireless networks.
- To improve throughput, average end-end delay and normalized routing load
of the network
Proposed System
An ETX metric module incorporates the following:
- Effect of link loss ratios
- Asymmetry in the loss ratios between the two directions of each link
- Use of the cross layer approach, where the information of the Data Link layer is used at the Network layer for routing.
Conclusion
- We have been able to implement ETX metric successfully in three protocols
namely AODV,TORA and HWMP(PROACTIVE and REACTIVE).
- Through the result analysis done in form of X-graph, bar graph and line graph,
performance of AODV-ETX,TORA-ETX and HWMP-ETXis better than AODV,TORA and HWMP.
- Hence we conclude that ETX approach is successfully used to route packets in the
wireless network.
