Abstract:

For heterogeneous networks, a method of multiradio transmission diversity is proposed in order to exploit the multiradio access diversity gain. The packet level forward error correction (FEC) is integrated with multiradio transmission at sender. In order to exploit the considerable multiradio transmission diversity (MRTD) gain and provide the efficiency of system throughput, the coded packet is adaptively allocated to each available radio access according to minimizing the probability of irrecoverable loss at receiver. The analysis and simulation on its performance are proven that the proposed scheme has optimal transmission reliability and efficiency especially in the terrible channel condition.

Key words: heterogeneous wireless networks, multiradio transmission diversity, packet level forward error correction, generic link layer
