Abstract

Efficient exploitation of spatial diversity is fundamentally important to resource critical wireless applications. A medium access protocol (MAC) for space division multiple access (SDMA) packet networks is proposed. The new protocol performs scheduling based on users´ spatial characteristics and quality-of-service (QoS) requirements to achieve throughput multiplication and reduction of packet delays. The system´s performance is evaluated under mixed audio and data traffic patterns and the results show that the new protocol can lead to a significant improvement in network performance
