Bandwidth Aggregation for Real-Time Applications in Heterogeneous Wireless Networks
Source: University of California
A variety of wireless interfaces are available for today's mobile user to access Internet content. When coverage areas of these different technologies overlap, a terminal equipped with multiple interfaces can use them simultaneously to improve the performance of its applications. In this paper, the authors motivate the advantages that can be had through simultaneous use of multiple interfaces and present a network layer architecture that enables diverse multi-access services. In particular, they explore in depth one such service provided by the architecture: Bandwidth AGgregation (BAG) for real-time applications. An important aspect of the architecture when providing BAG services for real-time applications is the scheduling algorithm that partitions the traffic onto different interfaces such that the QoS requirements of the application are met.
