The Design of Channel Estimation and Blocking Probability for Multi-Hop Wireless Communication Network
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 12
Abstract
The paper presents the design of channel estimation and blocking probability for multi-hop wireless communication network (MH-WCN). This work proposed a bidirectional network coding 4−hop transmission strategy and followed by 2N−hop WCNs. The proposed method follows two steps. Firstly, assign composite channel coefficients at desired nodes and then derived the MSE performance expression for the proposed LMMSE estimation scheme, and an optimal training scheme has been designed to minimize MSE. Secondly, Fault-tolerant wavelength assignment algorithm. This method checks for the establishment of fault-free path, when path established, assign a particular wavelength to the established path. The experimental results shows the LMMSE, blocking probability and ML estimators have demonstrated effectiveness to improve the estimation accuracy in 4−hop WCNs.
