Research on repairing mobile cache system of satellite Internet of Things based on fault-tolerant coding

Abstract

Different from source coding, which only emphasizes coding efficiency, fault-tolerant coding adds some redundant information during coding to strengthen the ability of error resistance, so as to obtain the best gain with the least redundancy. Therefore, the application of fault-tolerant coding in the repair of mobile cache system of satellite Internet of Things can effectively improve the security of information storage of satellite Internet of Things. Based on this, this paper introduces the repair method of mobile cache system of satellite Internet of Things based on fault-tolerant coding from the aspects of data deployment and data collection, so as to repair the invalid data in time and ensure the integrity and availability of the saved data. At the same time, a specific method to optimize its system parameters is proposed. The repair of mobile cache system of satellite Internet of Things based on fault-tolerant coding can effectively solve the disadvantages of low price and short service time of sensor node terminal equipment in Internet of Things, and avoid problems such as data storage failure or performance weakening of cache communication system caused by sensor leaving satellite coverage and power exhaustion, so as to provide corresponding reference for the development of satellite Internet of Things.
