| Summary: | 碩士 === 國立成功大學 === 電腦與通信工程研究所 === 95 === Mobile users are often involved in team activities and exhibit collaborative mobility in realistic ad-hoc network application scenarios. Due to diverse group mobility patterns, the network can remain partitioned for extended durations. This thesis describes an approach to reduce the communication disruptions by deploying forwarding nodes. The forwarding nodes explore periodically in order to gather network information for countering the influence from mobility and sparseness of node deployment. By selecting the rendezvous grids pair, the forwarding nodes can move to appropriate locations to recover communication. The mechanism has been implemented in the network simulator ns-2. The simulation results show that the mechanism can efficiently improve information availability and achieve the required communication quality.
