Proposal Of Shadowing Estimation Method To Improve Tcp Throughput In Road-To-Vehicle System |
Abstract | ||
|---|---|---|
This letter proposes a new differential power comparison (DPC) method, which accurately estimates the occurrence timing of shadowing at a mobile station (MS) by comparing the differential received power. In a road-to-vehicle TCP/IP communication system, the shadowing causes a lot of packets losses. They result in an extreme low throughput at an MS because packet retransmission increases in TCP layer. Though the technique of Freeze-TCP has proposed to overcome this problem, it must require an accurate estimation of shadowing with round trip time (RTT) in a road-to-vehicle communication (RVC) network. Computer simulations show that DPC method with 3 diversity antennas can estimate the occurrence timing of shadowing in high accuracy. |
