摘　　要：随着5G时代的到来,物联网的发展迎来一个新的里程碑,依托于物联网的智能家居也有了更大的发展前景,智能家居的普及是大势所趋。我国居民大多以小区模式居住,在此模式下无线传感网络覆盖范围变大、数据量变大会导致节点能耗较高,同时用户增多会导致并发访问量超载等问题。针对以上问题,论文提出了面向智能家居系统的节点能耗及访问容量优化方法,从优化路由算法、格式化数据传输格式和控制节点睡眠时间三个方面来对节点能耗进行优化,从在服务器Service层引入线程池、引入Redis缓存和优化数据库三个方面来提升系统的并发能力,降低响应时间。Most Chinese residents live in the community mode.In this mode,the coverage of wireless sensor network and the amount of data become larger,resulting in higher node energy consumption.At the same time,the increase of users will lead to con-current access overload and other problems.To solve the above problems,this paper proposes a node energy consumption and ac-cess capacity optimization method for smart home system,which optimizes node energy consumption from three aspects:optimizing routing algorithm,formatting data transmission format and controlling node sleep time.The concurrency of the system is improved and the response time from three aspects are reduced,which are introducing thread pool,Redis cache in server Service layer and optimizing database.
