Machine to machine communication in cellular networks

Packet switched cellular networks offer significant cost and capacity utilization benefits for machine to machine (M2M) communications. However, the current cellular systems facilitate that communications must be initiated by the mobile station, as the architecture lacks needed monitoring and controlling functions. This study presents an architecture that offers an operator based solution for the management of M2M communications in an operator network. The management interface of this system is implemented by using the SIP protocol and its messaging and presence extensions. The prototype implementation is tested and found to be functional but limited in terms of scalability and denial of service vulnerability. Suggestions are presented in order to rectify these issues
