Ex-Ett: Multi Objectives Expected Transmission Time for An Improved Link Quality Estimation
Abstract
Accurate and efficient wireless link quality evaluation in wireless networks is crucial in ensuring a
good end-to-end network performance. However, due to the dynamic nature of the wireless mobile networks,
estimating the link quality proves to be a challenge. This paper includes, a new link quality evaluation procedure
that jointly considers the MAC (media access control) throughput and PHY (physical layer) characteristics for a
more accurate link quality estimation. Our algorithm, termed as Extended Expected Transmission Time (Ex-
ETT), is implemented depended on IEEE 802.11 and shows a momentous enhancement, higher than 80%, in
terms of link quality estimation accuracy. The effectiveness of the proposed algorithm is demonstrated by an
improved end-to-end routing decisions in the network. The numerical results display that, comparing with
traditional method, the proposed Ex-ETT method lead to a better routing decisions in wireless mobile scenarios.
