Abstract

This paper proposed "Priority Scheduling and MultiPath Routing Protocol (RRPS) for preventing communication disruption in the urban environment" to minimize the disconnection or disruption of V2I and V2V communication in the urban environment where communication is frequently disconnected according to density. The flow of the RRPS is explained as follows. RSU Request Priority Scheduling (RRPS) is used to apply the priority of the request message prior to reaching the end line by using the Start Line and End Line, which are the management areas of the RSU). This paper also proposed MPRP (Multi Path Routing Protocol) design to set up the multipath to the destination. As a result, the proposed RRPS improves the processing efficiency of V2I by applying priority scheduling to the message of the vehicle requesting the information in the RSU, and can prevent the communication disconnection. Thereby, it is improved the transmission success probability.

본 논문에서 제안하는 "도심환경에서 통신 단절 예방을 위한 RRPS(Priority Scheduling and Multi Path Routing Protocol)"에서는 밀집도에 따라 통신의 단절이 빈번하게 일어나는 도심환경의 V2I 및 V2V통신의 단절을 최소화 하기 위하여, RSU의 관리 영역인 Start Line, End Line을 이용하여 End Line에 도달하기 전에 요청 메시지에 대한 우선순위를 적용하여 우선순위가 제일 높은 요청데이터를 먼저 처리할 수 있도록 하는 RRPS(RSU Request Priority Scheduling)알고리즘을 설계를 제안한다. 결과적으로 본 논문에서 제안하는 RRPS는 RSU내에 정보를 요청한 차량의 메시지에 대하여 우선순위 스케줄링을 적용하여 V2I의 처리효율을 향상하고, 통신 단절을 예방하여 전송 성공확률을 향상시키는 효과를 갖는다.
