摘要
物联网节点由于有限的尺寸和能量,其计算能力和存储空间一般会受到限制。为此,采用非对称方式,提出一种新的物联网通信协议。通过物联网节点与就近的服务器之间建立通信链路的方式,将原本由单一物联网节点执行的任务,转换为节点和服务器协作执行,将任务负载量在节点和服务器两端进行非对称分配,由服务器执行较高复杂度的运算,从而减少在节点端进行数据运算的能量消耗,满足物联网元件的节能需求。仿真结果表明,与传统的RSA加解密运算相比,利用非对称方式进行RSA加解密运算,可使物联网节点的运算时间和能量消耗减少20%以上,该协议能有效提高物联网节点的计算效率,延长节点的生命周期。
Due to the limited size and energy,the computing power and storage space of Internet of Things（IoT） nodes are always limited. For this problem, this paper proposes and designs a kind of loT communication protocol based on asymmetric mode. The protocol establishes the communication link between loT nodes and nearest server, and transforms the task which is originally executed by single node to compute between node and server. The protocol asymmetrically distributes between node and server, and assigns the server a more complex calculation, thus reduces the energy consumption of calculating of nodes, and realizes the energy-saving demand of loT nodes. Simulation results show that compared with traditional RSA encryption and decryption operations, the asymmetric mode can significantly reduce the calculate time and energy consumption, the range is about 20%. The protocol proposed in this paper effectively improves the computation efficiency, and prolongs the life of nodes.
