Efficient broadcast transmission algorithms based on opportunistic network coding
Ran Zhang, Isn Key · Journal of Communications · 2012
Opportunistic network coding(ONC) based broadcast transmission algorithms were proposed to improve the transmission efficiency for wireless single-hop networks.Based on the traditional wireless broadcast transmission model,ONC based solo combination packet broadcast transmission(ONCSB) algorithm and ONC based multiple combination packets broadcast transmission(ONCMB) algorithm were proposed respectively.By employing the method of combina-tion different lost packets with different strategies,the ONCSB and ONCMB can improve the throughput with recovering lost packets via a combination packet efficiently.The simulation results show that either ONCSB or ONCMB can lead to better transmission bandwidth performance compared with other algorithms under different wireless channel conditions.
