Wireless Sensor Network Routing Protocols: TEEN Protocol MATLAB Implementation

In wireless sensor networks, routing protocols play a crucial role in facilitating data transmission between sensor nodes to enable information exchange and sharing. TEEN (Threshold-sensitive Energy Efficient sensor Network protocol) represents a widely adopted flat routing protocol that employs a cluster-based architecture. This protocol organizes sensor nodes into distinct clusters and elects cluster heads to coordinate data forwarding operations. The MATLAB implementation of TEEN provides comprehensive simulation capabilities for analyzing protocol behavior. Key algorithmic components include: - Cluster formation algorithms that group nodes based on proximity and energy levels - Dynamic cluster head election mechanisms using weighted probability formulas - Dual-threshold (hard and soft threshold) data transmission control - Energy consumption modeling for transmission and reception operations Through MATLAB simulation, researchers can examine TEEN's adaptive response to environmental changes, evaluate energy efficiency metrics, and test various network configurations. The code typically implements: 1. Network initialization with random node deployment 2. Cluster head selection using residual energy calculations 3. Threshold-based data filtering and transmission logic 4. Performance metrics tracking (packet delivery ratio, energy consumption, network lifetime) When studying wireless sensor networks and routing protocols, experimenting with TEEN MATLAB code offers valuable insights into practical protocol implementation, parameter optimization, and performance validation under different network conditions.
