Application of automata in wireless sensor networks
Wireless Sensor Networks (WSNs) face critical challenges in balancing energy efficiency, security, and dynamic adaptability. This work synthesizes recent advancements in automata-based models to address these challenges, focusing on adaptive sampling, intrusion detection, and optimized routing. Key innovations include:

  1. Dynamic Sampling via Adaptive Automata: Monteiro Santos et al. proposed adaptive automata to dynamically adjust data sampling intervals based on environmental conditions. By switching between long intervals (e.g., 30 minutes) during normal operations and shorter intervals (e.g., 3 minutes) during anomalies, this approach tripled network lifetime in agricultural monitoring simulations.

  2. Secure Authentication with Cellular Automata (CA): Jamil et al. introduced a CA-based authentication scheme using tamper-resistant identity bits and chaotic Rule 30 transitions. This method reduced replay and forgery attacks while maintaining low computational overhead, achieving 96% packet delivery rates

  3. Hybrid Automata for Lifetime Analysis: Coleri et al. modeled WSN nodes as hybrid automata to predict energy consumption patterns. Simulations revealed nodes closer to base stations deplete energy 3–5× faster, informing strategies like tiered battery allocation and load balancing

  4. Topology Control Using CA: Bhende and Wagh leveraged CA to manage node states (active, idle, dead) in redundant deployments. Their TCA-1 and TCA-2 algorithms reduced simultaneous active nodes by 40%, extending network lifetime by 30% compared to static topologies

  5. Non-Volatile CA with Memristors: Yu et al. integrated memristors into CA cells to retain network states without continuous synchronization. This reduced communication overhead by 77% while maintaining 100% connectivity and 78% coverage in 40×40 node grids

  6. PSO-Optimized Learning DFA (LD²FA): Prithi and Sumathi combined dynamic deterministic finite automata with Particle Swarm Optimization (PSO) to detect Sybil and selective forwarding attacks. The framework improved throughput by 70% over lightweight IDS and extended network lifetime by 54% compared to genetic algorithms
