Abstract No one can deny the importance of mobility in modern communication networks, and the Internet is no exception. The internet engineering taskforce (IETF) has introduced the network mobility (NEMO) protocol to support a moving network. NEMO solves many problems of mobile internet protocol to support a moving group of users but introduces some problems of its own such as suboptimal routing and multiple levels of encapsulation. These problems occur because the NEMO basic support protocol does not support route optimization and nested mobile networks. Many solutions have been proposed in the literature to solve these problems. In this paper, we present a comprehensive survey of those solutions and discuss their advantages and disadvantages. We also outline the effect of these solutions on handovers, and a summary is provided in the form of a table at the end. In this paper, we back up our earlier work with a comprehensive discussion of the protocols included. © 2012 Institute of Electrical Engineers of Japan. Published by John Wiley & Sons, Inc.
