Even though sensory data computing is a core service in IoT, the issue of security continues to be a major challenge. The security and privacy of data and the underlying transmission medium affects service delivery. Power supply and the autonomous nature of WSNs are other notable challenges eminent in sensory data computing. Finally, the ability to handle and process real time data is a challenge that affects service delivery and quality assurance in crucial operations like health, transport, and military. Despite these challenges, sensory data computing continues to be an important service that enhances service delivery in an IoT environment. Proper management and efficient design of WSNs should be encouraged in an attempt to address these challenges. Also, sensory data computing should be structured in such a way that it adopts the use of modern technology for service delivery.
