Method of Autonomic Load Balancing for Long Polling in M2M Service System

In a Machine-to-Machine (M2M) service system that connects devices to the internet and provides various remote services, the long polling communication method is effective as a communication protocol that satisfies requirements of both security and immediacy simultaneously. It sustains a communication session among devices and servers for a definite period. For this reason, when a medium server for load balancing is introduced into a large-scale M2M service system, it might cause a performance bottleneck. As described in this paper, we propose an autonomic control method to achieve load balancing and load leveling using only devices and servers, without introducing a medium server. This study estimates the proposed method by simulation, demonstrates its effectiveness, and derives the conditions of proper operation parameters.
