N2 - With the tremendous growth of IoT, the role of IoT cloud gateways in facilitating communication between IoT devices and the cloud has become more important than ever before. Most previous studies have focused on developing interoperability between IoT and cloud to accommodate various radio protocols. However, they have often neglected the performance aspect of the IoT cloud gateway, leaving users with limited options: either purchasing multiple gateways or connecting only a small number of IoT devices. Through our comprehensive measurements and analysis, we identified five key issues in IoT cloud gateways related to high latency, CPU bottlenecks, inefficient network stacks on ARM, substantial encryption overhead, and the lack of priority support. To address these issues, we propose a new IoT cloud gateway - SegaNet. We carefully design with 1) multiple agents management, 2) efficient TLS encryption, and 3) priority-oriented message delivery. Our prototype evaluation shows up to 16.7 × lower latency and 4.5 × lower CPU consumption than gateways of the existing IoT-cloud ecosystem.
