Channel Uncertainty Effects on Multihop AF and DF Wireless Mobile Networks

Free registration required

Executive Summary

The main purpose of this paper is studying both the regenerative Decode-and-Forward (DF) and non-regenerative Amplify-and-Forward (AF) schemes for mobile wireless relay network under channel uncertainty. A wireless system consisting of one-source-one-destination mobile pair and N multihop mobile relay nodes is under investigation. The scenario being studied is appropriate for low power or widely spread network of mobile nodes, such as vehiculars, where transmitted signal can reach its first tier nodes only and degrades before reaching its second tier neighbors.
