Previous work on RSUs.

RSU TypeYearReferenceMain Features

fRSU2014[4](i) Roads are divided into cells
(ii) More fRSUs are deployed in a cell with more vehicles

fRSU2013[5](i) Roads are divided into zones
(ii) Less fRSUs are deployed in a zone with more vehicles

fRSU2013[6](i) More intersections are covered by less fRSUs

fRSU2015[7](i) Roads are divided into segments
(ii) More fRSUs are deployed in a cell with less vehicles

mRSU2011[8](i) Certain vehicles are used as mobile gateways (mRSUs) to extend the coverage of fRSUs
(ii) A position-based routing protocol based on V2V and V2I communications is proposed
(iii) No deployment issue of mRSUs is covered

mRSU2010[9](i) Buses (mRSUs) form mobile infrastructure
(ii) A position-based routing protocol is proposed based on the transmission quality of each road segment
(iii) No deployment issue of mRSUs is covered

mRSU2010[10](i) Buses (mRSUs) form mobile infrastructure
(ii) Each vehicle registers with a bus
(iii) A position-based routing protocol is proposed based on the transmission quality of each road segment
(iv) No deployment issue of mRSUs is covered

mRSU2013[11](i) Buses (mRSUs) form mobile infrastructure
(ii) Each vehicle registers with a bus or fRSU that can have the longest registration time
(iii) No deployment issue of mRSUs is covered

fRSU2016[12](i) Two types of mRSUs are defined according to whether the mRSU is controllable by an organization or not 
(ii) According to the RSU types and the given budget, the placement of RSUs is determined 
(iii) Uncontrollable mRSUs are given with the largest portion of the budget
