A Trusted Handoff Decision Scheme for the Next Generation Wireless Networks

Fourth Generation Wireless Networks (FGWN) consists of heterogeneous networks managed by different operators (or service providers). The provision of continuous services for mobile nodes is a main issue for the FGWN, Thus, it is necessary to provide seamless handover while moving in such environment. Moreover, the establishment of trust relationships between FGWN's entities poses a major challenge. In this regard, exchanging trust information between networks and mobile nodes is an important factor which guarantees a trusted handoff decision. This paper presents a Trusted Distributed Vertical Handoff Decision (T-DVHD) scheme, which provides trusted and seamless vertical handover. The simulation outputs show good performance of the T-DVHD in term of handoff delay, blocking rate and throughput.
