Initialization Procedure of Wireless Network Coding With Hierarchical Decode & Forward Strategy in Random Connectivity Networks
A Wireless Network Coding (WNC) a.k.a. a Physical Layer Network Coding in multi-source multi-node scenarios has shown its potential to increase network throughput compared to a communication based on an orthogonal separation of individual transmissions. In this paper, the authors analyze necessary steps that have to be done to initialize the WNC communication including mainly establishing of relay operations. In their set-up a core network (they named it a cloud), that provides the WNC capabilities of reliable source - destination communication, starts its operation with no system state (connectivity) knowledge.
