CL-OLSR takes into account four link quality impact factors in route calculation through the cross-layer operation mechanism： the node available bandwidth, the node load, the link delivery rate, and the link interference, and thus the effect of route selection is optimized greatly. The simulation results show that the proposed CL-OLSR protocol can not only improve the network throughput to a large extent, but also reduce the end-to-end delay, while achieving load balance route results.展开更多

Its nodes and hosts are all movable and self-configurable while simultaneously serving as routers to deliver data from sources to their respective destinations. Because routers in MANETs have to cooperate efficiently to meet the performance requirements, routing algorithms play a crucial role in MANET architecture design. In the past, tremendous works have been done on comparison and evaluation of routing algorithms using NS2 （network simulator 2）. This paper presents performance evaluations and analyses on the Proactive and Reactive routing protocols using NS3 （network simulator 3）, a relatively newer and more advanced version of NS2. This paper will also show simulation results of evaluating the drop rate, throughput, power consumption, and end-to-end delay of MANETs. Lastly, a performance justification of said simulation results will be presented.展开更多
