The Navy’s new Distributed Lethality strategy will require an extensive sensor network to support increased information requirements. Wireless sensor networks (WSN) for Intelligence, surveillance and reconnaissance (ISR) support offer a means to gather this information, and commercial-off-the-shelf (COTS) solutions offer an economical option for the required WSN components. Through computer simulation using the LEACH protocol and Raspberry Pi 3 Model B (RPi) parameters as the sensor nodes, this research explored the technical feasibility of using COTS technologies to implement a low-cost WSN. Simulations were designed to measure the number of rounds for RPi node death to compare performance against the current WSN structure using micro-sensor (MS) nodes. Measurements were taken from the RPi in transmit and receive modes to represent the joule/bit rate for energy used by RPi nodes in the simulation. Modified parameters were the percentage of nodes serving as cluster-head (CH), initial power for each node, number of nodes, and packet size from CH-to-base station. The results showed that adjustments to the Clusterhead-to base station packet size and the initial node power provided results where the RPi’s robustness and scalability capabilities equaled or exceeded the performance of the current micro-sensor networks.
