Coding nodes based state-aware data forwarding strategy for delay tolerant networks
Chun Ouyang · Journal of Chongqing University of Posts and Telecommunications · 2013
The application of network coding in delay tolerant networks(DTNs) can effectively improve the utilization of network resources,but it needs to adjust the number of coding nodes timely according to the network status.In order to optimize network resources,a data forwarding strategy for DTNs is proposed.According to the current network status,the number of required coding nodes can be estimated with the distributed manner.Moreover,to achieve reliable data forwarding with the lower overhead,the social property and available resources are considered for coding nodes selection.Results show that tour strategy decreases the network overhead ratio and increases the delivery ratio effectively;furthermore,the utilization of network resources is optimized dramatically.
