Wireless sensor networks (WSNs) consist of hundreds or thousands of sensor nodes that can communicate wirelessly and have computing abilities. These intelligent, self-configuring devices are spatially distributed autonomously to monitor conditions like temperature, pressure, and detect threats for military applications. WSNs have advanced due to MEMS technology, making sensor nodes smaller, lower cost, and more usable for both academic and industrial applications. However, sensor nodes have limited capabilities due to their small size, low memory, and low-powered processors.
