Performance analysis of the constructive interference flooding in wireless sensor networks

Constructive Interference Flooding (CI-Flooding) is a promising concurrent transmission technique for multiple senders synchronously transmitting the same packet, and interfere constructively at the common receiver in wireless sensor networks (WSNs). Constructive Interference (CI) enables reliable and fast network flooding, to decrease the scheduling overhead of MAC protocols, improve link quality of lossy links, achieve accurate time synchronization, and to realize efficient data collection. This paper presents a mathematical analysis of a WS N utilizing CI-Flooding, to investigate the network performance represented by the network throughput and lifetime. The mathematical analysis shows that the number of nodes, error displacement and distances between hops have the greatest impact on the network performance.
