Network mobility (NEMO) management is concerned about the mobility management of an entire wireless mobile network to provide uninterrupted network connectivity to many mobile devices moving together in the mobile network. This is particularly important for ubiquitous computing, which commonly means anytime, anywhere computing and communication. Most of the 3G and entire 4G and beyond wireless communication technology is all-IP. This growing use of IP devices in portable applications has created the demand for mobility support for entire networks of IP devices. NEMO solves this problem by extending Mobile IP. Devices on a mobile network are unaware of their network’s mobility; however, they are provided with uninterrupted Internet access even when the network changes its attachment point to the Internet. The main objective of NEMO is to provide continuous, optimal, and secure Internet access to all nodes and even recursively nested mobile sub-nets inside a moving network. Internet Engineering Task Force (IETF) is engaged in standardizing NEMO Basic Support protocol that ensures uninterrupted connectivity to nodes within a mobile network via a mobile router. This protocol extends the mechanisms utilized in the host mobility management protocol Mobile IPv6. There are few open problems remain to be addressed in NEMO. In this chapter, we discuss about NEMO basic support protocols, its features, and other related issues.

Mobility Management Protocol

Proxy Mobile IPV6 (PMIPV6) is a network based mobility management protocol which supports node’s mobility without the contribution from the respective mobile node. PMIPV6 is initially designed to support individual node mobility and it should be enhanced to support mobile network movement. NEMO-BSP is an existing protocol to support network mobility (NEMO) in PMIPV6 network. Due to the underlying differences in basic protocols, NEMO-BSP cannot be directly applied to PMIPV6 network. Mobility management signaling and data structures used for individual node’s mobility should be modified to support group nodes’ mobility management efficiently. Though a lot of research work is in progress to implement mobile network movement in PMIPV6, it is not yet standardized and each suffers with different shortcomings. This research work proposes modifications in NEMO-BSP and PMIPV6 to achieve NEMO support in PMIPV6. It mainly concentrates on optimizing the number and size of mobility signaling exchanged while mobile network or mobile network node changes its access point.

The proposals suggested so far can be can be classified in two different categories: on the one hand, NEMO solutions that consider MIPv6 as the base host mobility management protocol, and on the other hand, solutions that consider alternative base host mobility management protocols like SIP, LIN6, or HIP. Besides, a taxonomy on MIPv6 based NEMO protocols classifying them by considering which characteristics they aim to enhance is provided. It is important to point out that the selection of the base host mobility management protocol is fundamental to have as many demanded key features satisfied as possible by the NEMO protocol to be applied in the Intelligent Transportation System (ITS) context.

Mobility Management Protocol

Selection of a MIMO (Multiple Input Multiple Output) antenna to achieve high throughput, minimize errors, and optimize data speed is an important design issue. Radio resource management to provide Quality of Service (QoS) in WiMAX involves dynamic scheduling of resources according to the user’s priority, based classes Platinum, Gold, Silver, and Bronze. Mobility and handoff management in WiMAX is another important issue involving location update, signaling traffic and service delay, and call blocking and dropping. This chapter focuses on some issues concerning MIMO configuration to improve transmit diversity, developing an appropriate scheduling algorithm to improve QoS, and presenting a novel mobility management protocol THMIP (Three Level Hierarchical Mobile IP) in IEEE 802.16e environment to reduce signaling cost with respect to QoS parameters like throughput, end-to-end delay, interference, path loss, bit error rate, and Signal-to-Noise Ratio (SNR). For the simulation, the authors use OPNET Modeler and MATLAB.
