A Novel HMM-Based Learning Framework for Improving Dynamic Wireless Push Systems Performance

A new machine learning framework is introduced in this paper, based on Hidden Markov Model (HMM), designed to provide scheduling in dynamic wireless push systems. In realistic wireless systems, the clients' intentions change dynamically, hence a cognitive scheduling scheme is needed to estimate the desirability of the connected clients. The proposed scheduling scheme is enhanced with self-organized HMMs, supporting the network with an estimated expectation of the client intentions, since the system's environment characteristics alter dynamically and the base station (server side) has no a-priori knowledge of such changes. Compared to the original pure scheme, the proposed machine learning framework succeeds in predicting the clients' information desires and overcomes the limitation of the original static scheme, in terms of mean delay and system's efficiency.
