In this paper we describe a statistical analysis of a typical routing metric, Expected Transmission Time (ETT), used for path evaluation in multi-hop wireless networks. The need of statistics description is linked with the presence of network parameters uncertainty due to both a fading channel and ambiguity of nodes position. This analysis led us to define a statistical estimator, which allows controlling all these effects, in order to improve the quality of route choice during routing decisions.

Abstract
In this paper we describe a statistical analysis of a typical routing metric, Expected Transmission Time (ETT), used for path evaluation in multi-hop wireless networks. The need of statistics description is linked with the presence of network parameters uncertainty due to both a fading channel and ambiguity of nodes position. This analysis led us to define a statistical estimator, which allows controlling all these effects, in order to improve the quality of route choice during routing decisions.File in questo prodotto:
