Enhancing cellular infrastructures: a reflective approach

In this paper, we make a case of a reflective architecture for cellular systems as means to support flexibility and evolvability of the existing cellular network infrastructure to deal with a new generation of adaptive environments and applications. Existing systems are event/request driven and mechanisms to enable seamless adaptivity are limited. We show how the various proposed (but largely unimplemented) dynamic adaptation techniques for existing networks (GSM/CDMA) can be incorporated into a Reflective Cellular Architecture (RCA). Self representation in the RCA enables a new class of proactive and prediction-based information driven algorithms. We illustrate how the RCA enables novel techniques for observation and management of information in cellular networks, use the observed information in the design of effective coarse and fine grained location prediction meta-level services. We further illustrate how such meta-level services can be used to enhance the capabilities of today's cellular networks ranging from better radio resource management of the cellular infrastructure and customized alerting in disasters to effective utilization of other coexisting networks.
