Description

Technical Field

[0001] The present invention relates to the field of network control, and particularly to a method for upgrading a wireless ad hoc network. Background Art

[0002] In a wireless ad hoc network environment, software upgrade of devices is a necessary link to maintain the secure and stable operation of the network. Traditional upgrade methods often face challenges due to problems such as overly large upgrade packages, unstable signal-to-noise ratio during transmission, and long-term occupation of wireless resources. These problems are particularly prominent in remote deployment or large-scale networks.

[0003] Currently, most wireless ad hoc networks adopt a centralized full-scale upgrade strategy, that is, downloading the entire new version of the firmware at one time for replacement. This full-scale upgrade method not only increases the pressure on wireless bandwidth and extends the upgrade cycle, but also easily causes upgrade interruption at network edge nodes or weak signal areas, reducing the upgrade success rate and affecting network stability. Therefore, a method for upgrading a wireless ad hoc network is proposed. Summary of the Invention

By directly querying the device, the current operating status and configuration information of the device can be obtained, which helps to discover and solve problems in a timely manner; by comparing the version numbers of different devices, it can be quickly identified which devices need to be upgraded or updated; version number comparison is an intuitive and simple method that helps administrators make decisions quickly; in addition to version number comparison, function difference analysis can also be carried out to understand the function differences and new functions between different versions, which helps administrators evaluate the necessity and urgency of upgrades or updates, as well as the benefits and risks that upgrades or updates may bring; version query and comparison is an indispensable part of network device management. By using query commands based on the SNMP and SSH protocols, the quick acquisition and comparative analysis of the version information of network devices can be realized, which greatly improves the management efficiency and helps administrators better master the status and configuration information of network devices, providing strong support for subsequent maintenance and upgrade work; by using the SSH protocol for version query, the security of data transmission can be ensured. The SSH protocol uses encryption technology to prevent data from being stolen or tampered with during transmission, which helps to ensure the security of the network and prevent security vulnerabilities caused by version query; both the SNMP and SSH protocols are widely used network management protocols that support a variety of network devices and operating systems, which makes the query commands based on the SNMP and SSH protocols applicable to different network environments and device types, improving their versatility and practicality.

[0023] Please refer to Figure 1 In step six: upgrade order planning, there is also a planning algorithm included. The planning algorithm comprehensively considers factors such as network topology structure, hop count, and device priority, and dynamically adjusts the upgrade order. By comprehensively considering the network topology and the number of hops, the planning algorithm can select the optimal upgrade path, reduce data transmission latency and waiting time during the upgrade process. At the same time, dynamically adjusting the upgrade order can ensure that critical devices or paths are preferentially upgraded under limited resources, thereby shortening the overall upgrade time.

[0025] Please refer to Figure 1 , Step 8: Device status check, network connectivity test, and upgrade package integrity verification are also included in the verification and preparation before upgrade; Conducting device status check, network connectivity test, and upgrade package integrity verification before upgrade, the benefits are as follows: it can ensure that the device is in a healthy state, avoiding upgrade failure due to device failure; verifying network connectivity to ensure the smooth transmission of upgrade data; verifying the integrity of the upgrade package to prevent upgrade anomalies caused by file corruption or tampering. These measures together enhance the security and success rate of the upgrade process and ensure the stable operation of network devices.

[0026] Please refer to Figure 1 , Step 9: The integrity check also includes digital signature verification and hash value comparison steps, and the TLS / SSL protocol includes the steps of certificate verification and encrypted channel establishment; Conducting integrity check, digital signature verification and hash value comparison steps before upgrade, and using the TLS / SSL protocol for certificate verification and encrypted channel establishment, the benefits are as follows: digital signature verification and hash value comparison ensure the integrity and authenticity of the upgrade package, preventing the upgrade package from being tampered with or damaged; the TLS / SSL protocol ensures the identity security of both communication parties through certificate verification, and the establishment of an encrypted channel guarantees the confidentiality and integrity during the transmission of upgrade data, jointly enhancing the security and reliability of the upgrade process.
