Reliable Communication System using Stable Routes and the Position Based Delay Tolerant Transfer on MANETs

There are many researches and developments toward the utilization of MANETs in real case. As important challenging issues, the ensuring of each link\´s quality on the end-to-end pathways, and enabling the data conveyance on MANETs where the end-to-end route does not always exist can be listed. We developed the module that prevents weak links to be chosen as a route. This module decreases unexpected packet losses. Also, we introduced the protocol "position and motion direction based multi-hop delay tolerant transfer" that chooses the best intermediate node as the next data carrier. The simulation result marked high packet delivery ratio. Another noteworthy result is that the case with both position and direction information as the selection index overcomes the case only with position information
