Design and optimization of socket mechanism for services in Internet of Things

It is necessary for a server oriented to the Internet of Things (IOT) applications to provide countless connections with efficient and reliable service. Meanwhile the communication layer should try to lower the overhead. Therefore a highly efficient design for a socket server with buffer pool and a thread pool for concurrent request on the IOT platform is presented. This reduces the system overhead and buffer usage to the largest extent while faced with a large number of connections and digital requests. The simulation shows that a socket server with a thread pool and buffer pool could lower the overhead on the context switch of threads as well as the I/O blocking. This creates and destroys threads so as to energize the system.
