摘要：Flooding is an important communication primitive in mobile ad hoc networks. And also serves as a building block for more complex protocol such as routing protocol. In any flooding mechanism one must balance reliability against message overhead. On the one hand, increasing reliability generally involves sending a greater number of redundant messages and thus increases message overhead. Redundant messages are needed to reach all nodes and to recover from packet loss, hence reducing the overhead will generally decrease reliability. Selective broadcast of that packet improves the reliability as well as packet drop. These compensation packets are constructed from dropped data packets, based on techniques from AODV, AOMDV. The OLSR protocol (Multi-relay selection) inherits these stability of the link state algorithm, due to this proactive nature it has an advantage of having the route immediately available when needed. OLSR protocol is an optimization of a pure link state protocol for mobile ad hoc networks. The OLSR minimizes flooding of this control traffic by using only the selective nodes called multipoint relay, to diffuse this messages in networks. Only the multipoint relay of nodes transmits its broadcast messages.
