基于改进代码分发协议的远程代码更新技术研究
Research of Remote Code Update Technology Based on the Improved Code Distribution Agreement
摘要
Abstract
This paper aims at improving the classic code distribution agreement,controlling information by the Trickle proto?col for maintenance and version information for the entire network current distributing,through broadcast in the form of a distributed data,which makes communication within the scope of all nodes receiving the data possible. After the remote code update system de?sign,the system is divided into three parts,respectively for PC,the gateway node and sensor node. The key design is softwear which has the function of code updating of sensor nodes. The nodes of the storage space is divided into guiding parts and procedures, using different memory mapping to switch from the version. Experimental results show that the system can successfully complete re?mote code updates,and it can update multiple nodes at the same time,can support multiple hops update. In the event of a lost pack?age,it can also request data loss to ensure the integrity of the transmission code.关键词
