A METHOD OF DYNAMICALLY CHANGING MOBILE SWITCHING PATHS TO ENHANCE ICN MOBILITY SUPPORT

. Information-Centric Network (ICN) makes up for the shortcomings of the current TCP/IP network, separates names and addresses, and has inherent advantages in supporting mobility. These current ICN mobility support methods use a single fixed switching path to transmit mobile packets after routing optimization. When the fixed switching path is congested, the transmission delay and loss rate of mobile packets will increase significantly, which will greatly affect mobile users' Quality of Experience (QoE). Therefore, how to detect the congestion of the switching path during route optimization, and how to dynamically change the switching path when congestion occurs are problems to be solved urgently in ICN mobility support. In this paper, we first propose a mobility support method for dynamically changing mobile switching paths based on congestion detection. Then, we propose a late-binding node switching mechanism, which uses LateBinding Packets (LBPs) to detect mobile switching paths congestion in time and switches mobile packets to a non-congested candidate path. The mechanism includes two stages: congestion detection and late-binding node switching. Finally, experimental results show that our method can enhance mobility support and outperform other methods in terms of average packet delay, packet loss rate, handover delay, and throughput.
