The hierarchical structure in traditional wireless networks has led primarily to centralized deployment models. As some wireless networks are evolving away from the hierarchical structure, a distributed model for mobility management can be useful to them.

Fully distributed mobility management implies that both the data plane and the control plane are distributed.

A distributed mobility management scheme for a flat mobile network of access nodes is proposed in [Paper-Distributed.Dynamic.Mobility].

Motivation: Various attacks such as impersonation, denial of service, man-in-the-middle attacks, and so on, may be launched in a DMM deployment. For instance, an illegitimate node may attempt to access a network providing DMM. Another example is that a malicious node can forge a number of signaling messages thus redirecting traffic from its legitimate path. @@ -624,24 +624,22 @@ Research to Standards, June 2012.
