Efficient Binding Lifetime Determination Schemes in HMIPv6

Abstract

Mobile IP represents a global solution, providing mobility management for a wide variety of radio technologies, devices and applications. Significant research results relating to extensions for MIPv6 have been reported over the last several years. However practical and common issues exist within the technology, in particular, the specification of Binding Update Lifetime has a substantial impact on the system performance. In this paper, binding lifetime determination schemes are devised to obtain high energy-efficiency mobile nodes in HMIPv6. Some people may stay within some area for a long time and thus the related information can be very useful in decreasing the frequency of binding update messages. That is, if each user maintains a profile locally based on moving history; this can be very useful in fixing the lifetime in terms of current location. In addition, the resident time is occasionally affected by the daily arrival time as well as the subnet. Thus, we expand the scheme to consider the time region of arrival time per each subnet. We study the performance improvement of our schemes through extensive simulations.
