Admission Control Scheme for Reducing Signaling Storm in Wireless Network

Abstract

Reducing signaling storm in wireless networks has become a major goal in designing today’s wireless communication systems. In order to reduce signaling storm, this paper addresses the issues of scheduling the signaling resources in wireless networks subject to both quality of service (QoS) and priority constraints. The applications in wireless communication systems are divided into three types,namely always-on applications, voice applications and the other applications. For all the applications, an admission control scheme is proposed that incorporates the reconfiguration of idle resources and the QoS negotiation. The QoS negotiation usually contains the following parts, QoS reduction of the new application, QoS reduction of the applications which have accessed to the network and the resources compulsory possession. When the signaling resources are limited, the proposed admission control scheme can improve the successful access rate of voice applications and reduce the impact of signaling storm in wireless network.
