An Efficient Soft Handoff Scheme using Enhanced Resource Reservation Technique in Wireless MIPv6 Networks

초록

In a recent wireless network environments, dynamic host configuration protocol (DHCP) service is used to assign IP addresses to mobile terminals. In IPv6 networks, it is necessary to introduce the concept of handoff to support a seamless service to mobile terminals. In a general soft handoff technique used by code-division multiple access (CDMA) communication systems, the powers received to base station are simply compared to determine which base station will handle the signal to and from each mobile terminals. However, in IPv6 network, to transmit data-oriented services, it is necessary to support an enhanced soft handoff technique with more security and quality of service. In this paper, we propose a scheme to reduce a signaling process of hadoff in IPv6 network. Also, we propose a technique to reduce waster reservation resources and to guarantee quality of service(QOS) using DHCP.
