A medium access protocol exploiting multiuser-detection in CDMA ad-hoc networks

摘要: A new medium access protocol which exploits the physical layer capability of multiuser detection is proposed to help in improving throughput/delay performance ad-hoc networks. When more than one node has packets buffered for a common neighborhood, all such nodes can simultaneously transmit their receiver after reserving surrounding channel. This achieved our by extending (sender-initiated) CSMA/CA collision avoidance framework receiver-initiated technique and incorporating transmission power control. We analyze improvement throughput that be over basic sender-initiated network. Since via multi-packet reception influenced network activity as well, rolls back case no coordination from layer. For evaluation we simulate networks different topologies traffic configurations. observe scheme capable significantly
