Multipath data transmission using network coding scheme in heterogeneous wireless environment enhances information flows with optimal radio resource utility which addresses high traffic demands by end users in next generation wireless and secured traffic flows over the channels. Opportunistic channel allocation and scheduling technique in heterogeneous environment optimizes the traffic flows and network coding before forwarding towards destination significantly enhances the security level of traffics over the networks. This introduces optimal network throughput and minimizes the probability of data theft over multipath data flow architecture. With the availability of micro base stations (MBSs) and remote radio heads (RRHs), multipath traffic flows through MBSs and RRHs over high frequency channels or unlicensed channels increase network throughputs while network coded multicast over the available channels within Heterogeneous Cloud Radio Access Networks (H-CRAN) ensures data security over the network. In this paper, network coding scheme was implemented in H-CRAN environment for multipath traffic flow and data security measures were enhanced using network coded transmission resulting increased network throughput, reduced congestion at input buffer of nodes and secured transmission.
