One-dimensional mechanical relaying aided transmission on Ad hoc networks

다국어 초록 (Multilingual Abstract)

Mechanical Relay (McR) is a relaying architecture to enable data communications, where it can endure the transportation delay and intermittent disconnection. Existing vehicular infrastructures can be readily utilized for the mechanical relaying in the manner of moving natures, which brings the most significant consequences compared to conventional relaying schemes. User-to-user multi-hopping transmission has been notable transmission scheme for achieving higher throughput in the ad hoc networks. These two transmission schemes have a benefit of shortening the length of communication link.
In this thesis, we propose implementaion of McR and multi-hop transmission in ad hoc networks. First of all, operation precedure and protocol of McR and multi-hop transmission are invented. Secondly, SINR analysis is concerned for verifying the universal benefits of two transmission schemes. Network throughput is main performance criteria of concering transmission schemes. By comparing network throughput with the direct transmission, we verify the effect of two concerned transmission schemes.
Finally, we consider better methods to enhence basic McR performance. McR is influenced by the user’s position and intensity. User’s position is important to the calculation of transmission range. User and relay’s intensity ratio is the key elemenet of predicting the throughput performance. We propose 4 kinds of the user’s position and intensity ratio based schemes for the improvement of mechanical relaying throughput.
