In this paper we discuss and propose Optimized Link state Routing Protocol with reliability check function. This protocol is based on the link state algorithm such as Open Shortest Path First Routing Protocol. But it has a better advantage than OSPF routing protocols. OLSR has MPR to manage the flood message. It can reduce the flooding message significantly. But it has some flaws in the Mobile Ad hoc Network. Each node is connected wirelessly. It doesn't know which wireless path is broken or well working. In OLSR protocol, Link state is not considered. It is significantly important to care about this issue. We propose the way to increase the performance of OLSR protocol which cares about the link state in the wireless condition.
