The feasibility of obstacle awareness forwarding scheme in a visible light communication vehicular network

Abstract

A vehicular-to-vehicular (V2V) communication is a part of a vehicular ad-hoc network (VANET) that emerges recently due to the heavy traffic environment. V2V is a frequently changing network since it implements vehicles as mobile nodes. The challenges in implementing V2V are the relatively short duration of possible communication and the uneven city environment caused by high rise buildings or other objects that distract 
 the signal transmission. The limited transmitting duration between vehicles requires efficient coordination and communication. This work focuses on the utility of visible light communication in vehicular network (VLC-VN) in data transmitting and the obstacle awareness in the forwarding scheme based on our knowledge in previous researches. The result of evaluating the feasibility of VLC-VN forwarding in a freeway environment the transmission delay is lower than 1 second in 500 byte data transmission, however it reaches to only about 4% in throughput as a drawback.

A Simulation Approach to Improve the VANETs Communication

“…As breakdowns in connection relations often happen in VANETs, guaranteeing the stability of communication is extra difficult in VANETs as compared to normal MANETs. An actual and low-cost solution to decrease the mobility effect and develop the VANET network connectivity involves forming a clustering with hierarchical structure inside the network [1][2][3][4][5][6][7][8][9][10][11][12]. The clustering procedure is the separation of networks into small groups.…”

“…The latter can offer an active solution for the abovementioned problems. A vehicle is select to manage the connection among its Cluster Members (CM), called a Cluster Head (CH) an interacts with other sheets of a mutual network [2][3][4][5][6][7][8][9][10][11].…”
