TEEN Clustering Routing Algorithm

The TEEN Clustering Routing Algorithm is an adaptive protocol specifically designed for wireless sensor networks, with its core concept focusing on optimizing network energy consumption through dynamic clustering. This algorithm is particularly suitable for scenarios requiring high real-time performance, significantly extending the network lifecycle.

The algorithm employs a hierarchical structure comprising two critical phases: Cluster Formation Phase: The base station selects cluster head nodes according to a predetermined ratio, while remaining nodes join the nearest cluster head to form a topological structure. Cluster heads control member nodes' data transmission conditions by broadcasting hard thresholds and soft thresholds. Stable Communication Phase: Ordinary nodes activate transmission only when sensed data exceeds the hard threshold. If subsequent data variations surpass the soft threshold, transmission continues. This dual-threshold mechanism substantially reduces redundant data packets.

MATLAB implementation typically includes the following modules: Network initialization involves random node deployment with base station positioning Utilization of Received Signal Strength Indicator (RSSI) to calculate inter-node distances Dynamic adjustment of cluster head distribution density through competition radius Implementation of time-driven mechanisms for cluster head rotation to balance energy consumption

The algorithm achieves data aggregation and traffic control through threshold filtering, but requires careful consideration of threshold settings due to their trade-off impact on data accuracy and energy consumption.
