Neighbor Discovery in Peer-to-Peer Wireless Networks With Multi-Channel MPR Capability
The authors study the time duration of neighbor discovery in peer-to-peer wireless networks with multi-channel multi-packet reception capability. Radios with this capability, at any time slot, can either transmit messages in one channel or receive messages from all channels. This capability is provided by emerging CDMA/OFDMA techniques. Neighbor discovery in this scenario is different from other multi-packet reception scenarios like MIMO since collision can still happen in single channel. Neighbor discovery is a fundamental step for the initialization of wireless networks.
