The Sectorized Mobility Prediction Algorithm for Wireless Networks
R. Chellappa, Andrew Jennings, Nirmala Shenoy · 2003
One of the requirements for seamless mobility is efficient resource reservation and context transfer procedures during handoff. If context transfer and resource reservation can occur prior to handoff continuation of the same level of service as at the previous connection point is possible. Resource reservation is required to be non-aggressive for optimal use of limited bandwidth and a low call blocking probability. In this work we present a method of mobility prediction that can aid in achieving seamless mobility. In order to optimize the efficiency of a resource reservation algorithm we believe accurate prediction of the future movements of the user is required. The aims and contributions of this paper can be summarized as: - (a) Achieve accuracy in prediction with a considerable decrease in the total tracking area of the network and (b) a prediction algorithm that is efficient for both regular and random movements of users.
