A Simulink model for modified fountain codes

This paper introduces a Simulink model design for modified fountain code. The code is new version of the traditional Luby transform (LT) codes. constructs blocks required generation generator matrix limited-degree-hopping-segment (LDHS-LT) especially designed short length data files which have assigned great interest wireless sensor networks. It generates degrees in predetermined sequence but random and partitioned file segments. packets selection has been made serialy according to integer generated from both degree segment generators. tested using Monte Carlo simulation approach with conventional robust soliton distribution (RSD) generation, results approve better performance all testing parameter.
