Performance analysis of vertical handover techniques based on IEEE 802.21: Media independent handover standard

Internet protocol (IP)-based mobile systems are ushering new and faster technologies in wireless mobile networking. Therefore, the expectations from these network services with respect to data transfer rate and quality of service (QoS) are high. As such, meeting these requirements is the recent trend in modern wireless technologies. An important aspect regarding such improvements is the modification of handoff schemes between different networks. In this paper, we are focusing on the recent trends based on seamless handoff scheme in heterogeneous networks such as worldwide interoperability for microwave access (WiMAX) and long term evolution (LTE). The development of the session initiation protocol (SIP) Prior-INVITE scheme is an improvement on the earlier used SIP Re-INVITE method, which comes a long way in decreasing the average handoff delay. The performance analysis using software simulation on account of various parameters, such as handoff delay, cost of signaling and packet loss rate are accomplished in this work. The performance analysis demonstrates that the proposed scheme outperforms the ordinary cross-layer scheme and noncross-layer scheme in a vertical handover scenario.

The Media

Fourth Generation wireless networking (4G network) is expected to provide global roaming across different types of wireless and mobile networks. In this environment, roaming is seamless and users are always connected to the best network. Moreover, 4G networks will be packet switched systems entirely based on the IPv6 protocol. The essentiality of Quality of Service (QoS) and the heterogeneous nature of 4G pose high demands onto the mobility management technology. Due to this, one of the most challenging research areas for the 4G network is the design of intelligent mobility management techniques that take advantage of IP-based technologies to achieve global roaming among various access technologies. In order to address the issue of heterogeneity of the networks, IEEE 802.21 working group proposed Media Independent Handover (MIH). The scope of the IEEE 802.21 MIH standard is to develop a specification that provides link layer intelligence and other related network information to upper layers to optimize handovers between heterogeneous media. The IEEE 802.21 group defines the media independent handover function that will help mobile devices to roam across heterogeneous networks and stationary devices to switch over to any of the available heterogeneous networks around it.
