Wireless router selection strategy
Wireless router selection strategies can be divided into static and dynamic strategies. The static wireless router selection algorithm is also called a non-adaptive algorithm. It does not consider the current network's traffic and topology changes for wireless router selection. The dynamic wireless router selection algorithm is also called adaptive algorithm. It will change the wireless according to the actual situation of the current network and the change of topology structure.
Network information update time
The network information update time refers to how many times the network information source is updated in the dynamic strategy. It is related to the source of the network information and the adopted wireless router strategy. Obviously, if you do not use any network information, there is no need to update the network information; only use the local information, there is no problem, because the node knows its own operating status at any time, and for other network information sources, information Updates are related to wireless router strategies. For dynamic strategies, information updates can be periodic or triggered by changes in network status. Even if you use static strategies, you must know the changes in the network topology in a timely manner.
After understanding the design requirements and technical elements of the wireless router algorithm, the following further studies the wireless router algorithm. According to the wireless router selection strategy in Table 6-5, wireless router selection algorithms can be divided into static wireless router selection algorithms and dynamic wireless router selection algorithms. In the following, several static wireless router selection algorithms will be introduced. Then, several dynamic wireless router selection algorithms and their related wireless router selection protocols commonly used in today's computer networks are highlighted.
