Reliable Communications Scheme Based on Wireless Network Coding
Bo Zhang · Journal of Chinese Computer Systems · 2009
Network coding has been designed for wireless networks to improve the reliability,at the same time,many problems occurred: low throughput,and waste of network resources.Based on the work by M.Medard et al.,a new scheme: Neighborhood Network Coding Scheme is been designed.This scheme makes use of the broadcast nature of wireless channel,which can provide higher throughput and decrease the waste network resources.Further more,benefits are more obvious when neighborhood network coding scheme is used in multi-hop networks.Then,the upper bound of packet rate of the scheme is given with hypergraph mode.
