By supporting advanced multimedia applications and multitasking, recent Smartphone operation systems offer great functionality but make these devices even more difficult to serve. Now, network operators face a situation where many applications generate highly heterogeneous and bursty traffic patterns. To cope with this challenge, the authors introduce Context-Aware Resource Allocation (CARA). This new approach enables a scheduler to exploit new information from the users' environment, thereby, allocating its resources more efficiently. They describe CARA's high performance and feasibility by studying it as network utility optimization problem.
