Intrazone Routing Protocol
IARPThe Intrazone Routing Protocol (IARP) is needed for some routing protocols like ZRP (Zone Routing Protocol) or ZHLS (Zone-Based Hierarchical Link State Protocol). IARP is a proactive routing protocol and takes only the advantages from proactive routing. It is based on a Link State Protocol.The node monitors their own link state, which means their local neighbours, with a protocol named neighbour discovery protocol. This protocol provides current information about the node's neighbours (IP address of all the neighbours). Each node periodically sends a packet with new information to his direct neighbours. Then the nodes compute their information with the new arrived information. The node updates its routing table. A TTL (time to live) value is carried in the new information packet. The TTL is initialized by the node, which sent the packet with the new information, to R-1 hops. R is the zone radius. If a node receives the packet, he is going to update its routing table and the TTL value is decremented. If the value is 0 the packet is to be discarded. The packet with the local information stays in its own zone. No other zone can receive this information.
