These protocols can be divided into active routing protocols, on-demand routing protocols and hybrid routing protocols from the perspective of usage.
Active routing protocol is also called table-driven protocol. each wireless node maintains multiple routing tables£¬ including the next hop address to the destination node and routing cost. Each node periodically broadcasts routing information with neighboring nodes, and the node that received the information updates the information in the routing table.
The on-demand routing protocol is also called reactive routing protocol If a node wants to send data to another node, this protocol performs the route discovery process in the network. The routing information is stored in the routing table after the connection is established and it is only part of the overall network topology. When the transmission is completed the information in the routing table is discarded.
