Timer-Based Push Scheme for Online Social Networking Services in Wireless Networks

摘要

Nowadays, online social networking services in wireless networks are very popular. In this paper, we propose a timer-based push scheme (TPS) where a number of articles posted during a pre-defined time interval are pushed to users and thus the number of push operations and articles to be pulled can be reduced. We develop an analytical model for TPS and derive the optimal timer minimizing the total cost. Simulation results are given to show the effectiveness of TPS over the existing push N scheme and to validate the analytical results.
