Abstract:

In delay tolerant mobile networks,in view of buffers of nodes occupied by invalid notes for a long time in sparse networks,a mobile connection routing strategy combining with count-down timer and method of buffer-releasing-enhanced was put forward.This routing strategy can fasten the speed of buffers release.The effects of mobility/speed,communication range and number of nodes and notes valid time and size of simulation area on routing performance were studied.The simulation results indicate that "Buffer-release-enhanced weighted mobile connection routing" is able to guarantee the validity of message delivery and improve the efficiency of the networks.

Key words: communication technology, delay tolerant mobile networks, random waypoint model, routing, buffer release
