Exploiting Constructive Interference for Scalable Flooding in Wireless Networks
Exploiting constructive interference in wireless networks is an emerging trend for it allows multiple senders transmit an identical packet simultaneously. Constructive interference based flooding can realize millisecond network flooding latency and sub-microsecond time synchronization accuracy, require no network state information and adapt to topology changes. However, constructive interference has a precondition to function, namely, the maximum temporal displacement of concurrent packet transmissions should be less than a given hardware constrained threshold. The authors disclose that constructive interference based flooding suffers the scalability problem.
