Securing Topology Control in SDWSNs Using Identity‐Based Cryptography

Journal of Sensors, Volume 2023, Issue 1, 2023., 2023
In software‐defined wireless sensor networks (SDWSNs), topology control is a fundamental procedure to maintain the global network topology. However, the open wireless channels of SDWSNs make it possible for an attacker to eavesdrop, replay, or modify the topology messages, thus posing a great threat to the network operations.
