Abstract	Blockchain technology has become a viable way to improve Wireless Sensor Networks' (WSNs') security, transparency, and dependability. Nonetheless, the performance, scalability, and energy efficiency of these systems are greatly impacted by the consensus mechanism selection. In the context of blockchain-integrated WSNs, this paper compares two popular consensus algorithms: Proof of Work (PoW) and Proof of Authority (PoA). Key performance metrics such energy usage, processing overhead, latency, scalability, and security are the main emphasis of the analysis. The findings show that PoW is appropriate for WSNs because after the attack, the blockchain remains valid and maintains its integrity, ensuring that the stored data is accurate and consistent. PoA, on the other hand, is inappropriate for WSN contexts, it compromises the integrity of the blockchain, making it less trustworthy and susceptible to manipulation.
