This paper examines the performance of DTN bundling layers against native protocols for radio data network with a view to possible deployment for emergency communications purposes. The authors conducted experiments with an existing DTN convergence layer in both AX.25 point-to-point and D-Star multi-hop communications links with hidden transmitters. The experimental results show that the DTN system exhibits marginally better performance than TCP/IP, appears to perform better where there are hidden transmitters, and has a more compact link utilisation pattern than TCP/IP. However, situations where obvious improvements can still be made were also identified.
