Recent developments in wireless communications, digital electronics, and micro-electro-mechanical systems
(MEMS) have allowed for the creation of low-cost, low-power, multifunctional sensor nodes that are both compact
and capable of short-range communication. The concept of sensor networks based on the collaborative effort of a
large number of nodes is influenced by these tiny sensor nodes, which comprise of data processing, sensing, and
communication components. When compared to conventional sensors, sensor networks are a major improvement.
Large numbers of sensor nodes are deployed in close proximity to or inside the phenomenon to create a sensor
network. Instead than being fixed in one spot, the sensor nodes may move about on their own will. The military, the
environment, and even health care are just a few of the numerous potential uses for WSNs. Limitations in compute
power, memory size, available energy, the ability to avoid physical capture, and the usage of unsecured wireless
communication routes are just a few of the issues plaguing WSNs. Due to these limitations, securing WSNs might be
difficult.
