Abstract: Expected Transmission Count (ETX) has gained popularity due to identifying a high-throughput path in the multihop wireless network. However, the oscillatory network may not work correctly with a high traffic load; the probe packets may be lost or queued. This paper proposes a parameterised solution (data rate tuning and packet size adjustment) to minimise packet losses. Experimental results indicate that the network's performance is improved using ETX as a routing metric by tuning data rates and adjusting packet size. The results show that by keeping the data rate under 200 kbps and a packet size of 256 bytes, the performance of the OLSR-ETX routing protocol has improved in the oscillatory network. Finally, we have evaluated the OLSR-ETX parameterised-based solution with OLSR-ETX in oscillation scenarios concerning packet loss ratio. The results show that a parameterised-based solution improves the functionality of the routing protocols in the oscillatory network.

Keywords: ETX; OLSR-ETX; OLSR; oscillatory network; packet loss ratio.
