Research on inter Hospital and Ambulance Data Transmission using LT-Coding over VANET
Early and well monitored pre-hospital rescue contributes to endangered patients survival and low mortality.Ambulances are likely to be prevented from reaching hospital in time by poor traffic conditions.Existing methods of communication through Radio such as 2G/3G are faced with the problems of narrow bandwidth,high cost and low quality.We introduce a new way to transmit large amounts of vital data from ambulance to hospital over VANET.To solve the unavoidable packet loss,we encode all data by LT-code.This makes receiver to be able to restore all data under the circumstance of any percentage of packet loss,with only the cost of sending more encoded message instead of ARQ.In the situation of 10%-20% packet loss rate,the simulation results show the perfect data restoring.The great amount of feed backing needed by ARQ is also eliminated by LT-coding.
