High Throughput Routing Based on SNR Prediction for Variable Mobility Nodes

Multi-hop inter-vehicle communication is considered as one of methods for area expansion with distributed manner in ITS (Intelligent Transport System). In multi-hop networks, a route decision called routing for relaying data is important. In previous research, a new routing protocol which is based on prediction of LET (link expiration time) has been proposed to improve the communication success probability in mobility environment. However, the route decided by the previous routing protocol needs a long time for transmission, because this route may have low throughput due to long distance link. In this paper, by using a SNR (Signal to Noise Ratio) prediction based on the node location and mobility, the authors propose a new routing protocol. In this protocol, the delay times depending on the amount of the requested data through each route are predicted, and the route with the minimum delay time is selected. Through the computer simulation, the authors can confirm that the proposed routing protocol can achieve high end-to-end throughput and short delay compared with the conventional routing protocol.
