Call for Papers International Workshop on Mobility Management for Flat Networks 2011


International Workshop
on Mobility Management for Flat Networks


4 October 2011

In conjunction with the 14th International Symposium on Wireless Personal Multimedia Communications

3-6 October, 2011

Brest, France


Cellular networks architectures rely on hierarchical and centralised mobility anchoring functions tracking mobile nodes location and movements while supporting mobile traffic management and indirections. It is now recognized that such approaches lead to scalability issues like the creation of networks bottlenecks in central mobility anchoring functions as well as efficiency issues in cascading several per-user traffic encapsulation/de-capsulation functions. Hence, with the exponential growth in mobile data services usage, scalability and quality of service issues are foreseen even if most of users are not on the move while communicating.

Considering the current trend in flattening networks architectures, new means of supporting mobility can be envisaged in a more distributed and dynamic fashion. Such considerations include end-hosts and network schemes.

In end-hosts schemes, mobility is provided at end-hosts level only, i.e. without requiring mobility management functions support in the network. Some examples are the use of facility offered by transport (M-TCP, SCTP) or application (SIP, HTTP Streaming) layer protocols in switching IP addresses used for end-to-end communications.

In network schemes, new distributed mobility management approaches consider the distribution of anchoring functions among flat networking entities. The main motivation is the elimination of nowadays single point of failures and user traffic bottlenecks. Thus, mobility related working groups in the IETF are now exploring requirements and solutions supporting DMM (Distributed Mobility Management). These new approaches promise the delivery of a better quality of service together with more open networks, well suited to the provision of heterogeneous access and offload solutions. They are also well suited for the integration with both content networking and cloud networking functions at the network edge. However, they may introduce new issues like security or location concerns among others whereas there consideration in the evolution of cellular networks architectures like the EPC one is not yet foreseen in the 3GPP.


The goal of this workshop is to provide and further analyse a comprehensive vision in the design and issues for mobility management schemes in flat networks.
