【摘要】：在物联网接收数据流速度出现较大波动的情况下,会导致节点任务负载量过大,影响整个物联网的整体性能。当前分配系统大多采用负载均衡策略,忽略了节点间传输数量迅速增加的情况,导致时间延迟和能耗增加。为此,设计了一种新的物联网节点任务负载量非对称分配系统。当物联网节点接收到新的任务后,利用非对称分类策略对任务负载量进行分配,选择最佳转移服务器,以保证节点任务负载量分配过程中通信链路的稳定性,给出服务器选择过程。利用"握手"操作交换物联网节点和服务器的计算能力信息,获取物联网节点和服务器进行负载处理的具体比例,实现非对称分配。实验结果表明,所设计系统能耗和时延较低,有效带宽利用率较高。
[Abstract]:Under the condition that the speed of receiving data stream fluctuates greatly in the Internet of things, the load of node task will be too large, which will affect the overall performance of the whole Internet of things. At present, most of the distribution systems adopt load balancing strategy. The rapid increase in the number of transmissions between nodes is ignored, which leads to the increase of time delay and energy consumption. Therefore, a new load asymmetry distribution system for IOT nodes is designed. When the IOT node receives the new task, In order to ensure the stability of communication link in the process of task load allocation, the task load is allocated by asymmetric classification strategy and the optimal transfer server is selected. The process of server selection is given. The computing power information of the node and server is exchanged by "handshake" operation, the specific proportion of load processing between the node and server is obtained, and the asymmetric distribution is realized. The experimental results show that, The designed system has low energy consumption and delay and high utilization of effective bandwidth.
