With the requirement for remote control of unmanned aerial vehicles (UAV) becoming more frequent in scenarios where the environment is inaccessible or hazardous to human beings (e.g. disaster recovery); remote functionality of a UAV is generally implemented over wireless networked control systems (WNCS). The nature of the wireless broadcast allows attackers to exploit security vulnerabilities through passive and active attacks; consequently, cryptography is often selected as a countermeasure to the aforementioned attacks. This paper analyses simulation undertaken and proposes a model to balance the relationship between throughput and latency for a secure multi-hop communication link. Results obtained indicate that throughput is more influential up to two hops from the initial transmitting device; conversely, latency is the determining factor after two hops.
