Dear All, please let me advertise you two quite new and supposedly interesting HIP related articles in the area of distributed mobility management and flat network architectures: Title: Evaluation and Comparison of Signaling Protocol Alternatives for the Ultra Flat Architecture http://www.mcl.hu/~goodzi/Evaluation_and_Comparison_of_Signaling_Protocol_Alternatives_for_the_Ultra_Flat_Architecture_ICSNC2010.pdf Title: A Delegation-based HIP Signaling Scheme for the Ultra Flat Architecture http://www.mcl.hu/~goodzi/A_Delegation-based_HIP_Signaling_Scheme_for_the_Ultra_Flat_Architecture_IWSCN2010.pdf I hope you will find insteresting stuff in the above papers, and also that you will provide us with feedbacks, hints, remarks, etc. for our ongoing and future work.
