ANC-ERA: Random Access for Analog Network Coding in Wireless Networks


Analog network coding (ANC) is effective in improving spectrum efficiency. To coordinate ANC among multiple nodes while not looking forward to complicated scheduling algorithm and network optimization, a replacement random access MAC protocol, called ANC-ERA, is developed to dynamically kind ANC-cooperation teams in an accidental network. ANC-ERA includes several key mechanisms to maintain high performance in medium access. First, network allocation vectors (NAV) of control frames are properly set to avoid over-blocking of channel access. Second, a channel occupation frame (COF) is added to safeguard vulnerable periods during the formation of ANC cooperation. Third, an ACK diversity mechanism is meant to scale back potentially high ACK loss chance in ANC-based mostly wireless networks. Since forming an ANC cooperation relies on bi-directional traffic between the initiator and the cooperator, the throughput gain from ANC drops dramatically if bi-directional traffic is not on the market. To avoid this issue, the fourth key mechanism, referred to as flow compensation, is designed to form totally different varieties of ANC cooperation among neighboring nodes of the initiator and therefore the cooperator. Both theoretical analysis and simulations are conducted to evaluate ANC-ERA. Performance results show that ANC-ERA works effectively in unintentional networks and significantly outperforms existing random access MAC protocols.
