An Improved Network Coding-Based Cooperative Content Distribution Scheme

Reducing the additional computational overheads caused by network coding operations in the a novel cooperative content distribution paradigm which is based on network coding is valuable for both theoretical interests and practical interests. Regretably, little work about this problem, especially from the perspective of practical interests, has been reported in the present literature. To issue this problem, in this paper, we propose an improved network coding scheme which is based on the new mechanisms of clustered network coding, random choice and independence checking. Simulation results show that the proposed scheme can reduce the additional computational overheads significantly and achieve better performance than current used network coding scheme.
