Routing protocol research for wireless quantum networks based on resource reservation

Abstract

In wireless quantum communication networks, existing AODV routing protocols can guarantee the stability of quantum entangled channels. However, the protocol takes a long time to establish the quantum channel on average, and it also consumes many entanglement resources. In order to solve the above problems, a routing protocol for wireless quantum networks based on resource reservation is proposed in this paper. Before the source node sends the quantum state information to the destination node, the proposed protocol estimates the quantum state information to be transmitted and writes the resource estimation value into the routing request message. A broadcast routing request message can not only satisfy the requirement of quantum data transmission, but also ensure that the number of hops is as small as possible. Simulation results show that the proposed protocol can effectively shorten the time of establishing quantum channels, reduce the consumption of entanglement resources, and improve the communication efficiency of wireless quantum communication networks. It has good practical value.
