The inefficient usage of limited radio spectrum resources with its increased demand has opened the doors for an innovative communication technology. The recently proposed concept of cognitive radio network can use the licensed bands of primary users for its data transmission without causing interference to them. The LT (Luby Transform) code and Raptor code, types of Fountain codes (class of era...
Using information from a recent Rb two-color photoassociation experiment, we evaluate the merits of fountain clocks based on Rb and Rb isotopes as alternatives to Cs and find that they offer significant advantages. In the case of Rb the collisionally induced fractional frequency shift is 15 times smaller than for Cs. This small shift is associated with a small difference in the triplet and sing...
Fountain codes are widely employed to improve reliability and efficiency in wireless communication systems due their simple coding mechanisms. In this letter, we propose an opportunistic decoding recoding mechanism with coordinative routing algorithm for fountain the expected transmission counts (ETX) performance reduce computational complexity of at each relay multi-hop sensor networks. The fu...
