Abstract

Current cellular networks are often overloaded by Smartphone traffic, while the users' Quality of Service (QoS) demands are not met. To cope with this problem, we demonstrate a new Radio Resource Management (RRM) approach. With Context-Aware Resource Allocation (CARA), the base station's scheduler (i) observes Context Information (CI) from the user's environment and (ii) utilizes this knowledge for an efficient throughput-delay tradeoff. After introducing our framework for accessing CI from the handheld's applications and operating system,we use time-utility functions to develop a practical scheduling algorithm. Studying this heuristic under various traffic assumptions shows that our context-aware scheduler can support three times the load of Proportional Fair (PF) scheduling, at equal capacity and utility. Thus, even a small degree of context information increases the wireless links' efficiency without sacrificing the users' QoS.
