Performance increment of hybrid ad.hoc network coexisting fixed node and mobile node

This study evaluated the level of performance improvement in the form of a simulated experiment by adding fixed node in the middle of the network as a way to improve mobile ad.hoc network performance. The result showed that the performance level was much higher when fixed node was used together than when mobile node was used only, and the comparison of the mobile speed of mobile node also showed that use of fixed node together had higher performance. Moreover, the evaluation in accordance with the number of fixed node showed that more number of fixed node had shorter time delay. The method suggested in this study has a problem to add fixed node in the middle of mobile ad.hoc network but it will be effective to use for the network which requires faster throughput with high reliability despite the cost increase after comparing the relationship between the cost and throughput. Further study following this on how many fixed node should be added on the ad.hoc network will ensure establishment of more reliable ad.hoc network.
