Abstract: The Optimized Link State Routing Protocol (OLSR)is an IP routing protocol optimized for mobile ad hoc networks, which can also be used on other wireless ad hoc networks. OLSR is a proactive link-state routing protocol which uses hello and topology control (TC) messages to discover and then disseminate link state information throughout the mobile ad hoc network. The original definition of OLSR does not include any provisions for sensing of link quality; it simply assumes that a link is up if a number of hello packets have been received recently OLSR is based on the MPR (Multipoint Relay) concept to offer an efficient flooding technique and to build shortest routes. The MPR selection according to native OLSR is unable to build routes satisfying a given QoS request because it only allows shortest routes that do not take into consideration any other route metrics (bandwidth, delay …). So our approach is to find a mechanism to improve the QoS of the OLSR protocol in terms of weighted CI and delay. Weighted CI is the combined QoS metric of link capacity and connectivity. Thus, these optimized paths refer to the paths which have enough link capacity and are robust to link failures. We construct the simulation to demonstrate that the proposed algorithm can improve performances over OLSR protocol, and are also flexible enough to deliver services in highly mobility networks.
