چکیده
Wireless networking has become an important area of research in academic and industry. Worldwide Interoperability for Microwave Access (WiMAX) is a technology that bridges the gap between fixed and mobile access and offer the same subscriber experience for fixed and mobile user. Major issues arising in WiMAX network is the selection of the optimal path between any two nodes and route stability. A method that has been advocated to improve routing efficiency is to select the most stable path so as to reduce routing overhead due to rerouting instability problem. Implementing three routing protocols (AODV, DSDV and OLSR) for Mobile WiMAX environment is done under Random Direction Mobility Model. An assumption of each subscriber station has its routing capabilities within its own network is prepared. Random Direction Mobility model provide better efficiency by The performance matrix includes Routing Overhead, Packet Delivery ratio (PDR), Throughput, End to End Delay, and number of packet Loss were identified. Result and evaluation is done in NS-3.13 simulator for the comparison on the performance analysis. Successfully results found that OLSR protocol outperform the AODV and DSDV and improve efficiency of WiMAX .

Major issue arising in mobile ad hoc networks (MANETs) is the selection of the optimal path between any two nodes. A method that has been advocated to improve routing efficiency is to select the most stable path so as to reduce the latency and the overhead due to re-routing instability problem. We study both the availability and the duration probability of a routing path that is subject to link...

متن کاملTCP Traffic Based Performance Comparison of Manet Routing Protocol
In Mobile Ad hoc network (MANETS), no fixed infrastructure is available. Different wireless hosts are free to move from one location to another without any centralized administration, so, the topology changes rapidly or unpredictably. Every node operates as router as well as an end system. Routing in MANETs has been a challenging task ever since the wireless networks came into existence. The ma...
