In this paper, novel simultaneous query techniques are proposed for wireless networks, which allow the access point (AP) of the network to gather key control information from active nodes in the network at low overhead. The query techniques are based on OFDM, and include the analog bloom filter (ABF), with which active nodes send signals simultaneously on randomly selected subcarriers to inform the...
In this paper, we study the packet scheduling problem in wireless LANs with the one-sender-multiple-receiver (OSMR) transmission technique. OSMR allows the access point (AP) to send distinct packets to multiple nodes simultaneously, and has great potential in improving the network downlink throughput. We note that the AP needs a packet scheduling algorithm to make the decision of when a packet should...
