Mobility and anonymity are two essential properties desirable in IP-based networks. In this paper, we aim to address the issue on how to achieve mobility and anonymity concurrently. At a glance, these two properties seem to be contradictory. This is partly due to the fact that there exists no single definition that clearly defines these notions. We approach this problem by firstly define these properties formally and address the problem of achieving these properties at the same time. Then, we proceed with a concrete construction based on an existing IP-based network, which is Tor. Without losing generality, our method can be applied to any other existing network, such as Morphmix or Tarzan. We highlight the difficulty of achieving mobility and anonymity concurrently although it seems trivial to merge these two properties altogether. Finally, we evaluate our proposed construction based on the definition that we have developed. Our work can be seen as the first attempt towards formalizing the notions of mobility, anonymity and location privacy.
