| Abstract(in English) | For concurrently use of multiple various radio systems, bandwidth aggregation technology is one of the key issues to achieve high speed data access in combination with optimal use of wireless resources. We have already proposed the Cognitive Convergence Layer (CCL) and the Resource Time Sharing Algorithm (RTSA) in a former study showing improved packet distribution via multiple wireless links. CCL is a architecture of bandwidth aggregation and RTSA is a packet allocation algorithm for high performance bandwidth aggregation. In multiple WLAN access environments, if a link performance of one node decreases, the other node's performance decreases, too. For avoiding such affect, the base station needs to manage and control the radio resource. In this report, for the radio resource management at the base station, we present extensions of the CCL and RTSA. The extended CCL has multiple CCL queues to separately manage the radio resource of each destination node. RTSA is extended to switch between the CCL queues based on the state of the time resource which we have defined. Simulation results of the multiple access environment show that the extended CCL and RTSA can keep the throughput constant if one node's link quality becomes bad. |
