VANET Networks are one of the main next generation wireless networks which are envisaged to be an integration of homogeneous and heterogeneous wireless networks. The inter-networking of these wireless networks with the Internet will provide ubiquitous access to roaming network users. However, a seamless handover mechanism with negligible handover delay is required to maintain active connections during roaming across these networks. Several solutions, mainly involving host-based localized mobility management schemes, have been widely proposed to reduce handover delay among homogeneous and heterogeneous wireless networks. However, the handover delay remains high and unacceptable for delay-sensitive services such as real-time and multimedia services. Moreover, these services will be very common in next generation wireless networks. Unfortunately, these widely proposed host-based localized mobility management schemes involve the vehicle in mobility-related signalling hence effectively increasing the handover delay. Furthermore, these schemes do not properly address the advanced handover scenarios envisaged in future wireless networks. This paper, therefore, proposes a VANET mobility management framework utilizing cross-layer design, the IEEE 802.21 future standard, and the recently emerged network-based localized mobility management protocol, Proxy Mobile IPv6, to further reduce handover delay.

Interactive 3D

The explosive development of Internet and wireless communication has made personal communication more convenient. People can use a handy wireless device to transfer different kinds of data such as voice data, text data, and multimedia data. Multimedia streaming, video conferencing, and on-line interactive 3D games are expected to attract an increasing number of users in the future. The bandwidth requirement would be high and the heterogeneous terminals would generally provide limited resource, such as low processing power, low battery life and limited data rate capabilities. These applications would be the major challenge for wireless networks. Although the traditional layered protocol stacks have been used for many years, they are not suitable for the next generation wireless networks and the mobile systems. Due to the time varying transmission of the wireless channel and the dynamic resource requirements of different application, the traditional layered approach to the mobile multimedia communication is full of challenges to meet the user requirement on performance and efficiency. Cross-layer design is an interesting research topic that actively exploits the dependence between different protocol layers to obtain performance gains. The authors performed a survey and introduced the cross-layer design principles and issues for different research topics, including QoS, mobility, security, application, and the next generation wireless communication.

Layered Design

This chapter introduces the cross layer design for resource allocation over multimedia wireless networks. Conventional layered packet scheduling and call admission control schemes are presented and a number of cross-layered protocols that are recently proposed are investigated. The chapter highlights the QoS improvement and the performance gain obtained while considering the interlayer dependencies concept for various real-time and non-real-time applications. The authors hope that this chapter will assist in the understanding of the cross layering and its enhancement of the layered design for QoS provisioning in future multimedia wireless networks.
