Trust Based Inter-Domain Handoff Mechanism in Heterogeneous Wireless Networks

According to the difference of management entities,heterogeneous wireless networks are compartmentalized to different domains.Mobile nodes need inter-domain handoff frequently.For the validity of entities' identity and behaviors during the vertical handoff,a trust-based inter-domain handoff mechanism has been designed.This mechanism not only optimizes the performance of the vertical handoff,but also keeps away the untrustworthy behaviors between domains.
