“…Nowadays, the distribution of real-time multimedia content over Vehicular Ad-Hoc Networks (VANETs) is becoming a reality and allowing drivers/passengers to have new experiences with on-road videos in a smart city [2,3]. According to Cisco, video traffic will represent over 90% of the global IP data in a few years, where thousands of users will produce, share, and consume multimedia services ubiquitously, including in their vehicles.…”

Vehicular ad hoc network (VANETs) being a sub class of MANET is a challenging field of wireless communication. It is a sensible way of using infrastructure fewer networks augmented with Intelligent Transportation System (ITS). It is an emerging trend now days for vehicles to be equipped with an embedded on-board computing unit with communication capabilities to enhance the overall driving experience. Such a system enables vehicle to vehicle and vehicle-toinfrastructure communication and provides vehicles with upto-date route and traffic information. Due to its highly dynamic topology as well as occurring often disconnection among vehicles, various categories of protocols have designed for its efficient and reliable working. While driving, a large amount of data and information are accessible to everyone. Many attractive applications over vehicular ad hoc network (VANETs) need data to be transmitted to the remote destinations through multiple paths, but some unique characteristics of VANETs incur unstable data delivery performances. Efficient data dissemination to a desired number of receivers in a vehicular ad hoc network (VANET) is a new issue and a challenging one considering the dynamic nature of VANETs. This paper presents an overview on simple and robust dissemination technique that efficiently deals with data dissemination in both dense and sparse vehicular networks. This technique divides the users in two categories and it takes three cases.

“…It takes the moving direction and the distance as the inputs of fuzzy logic and improves the delivery ratio. A seamless streaming dissemination system for vehicular networks is designed in [16]. It uses fuzzy logic to check if a roadside unit or a vehicular node can be a candidate to transfer stream data for users or not.…”

“…Although both of them utilize backbone nodes to forward data, SFN improves the backbone selection and the backbone network construction. Firstly, SBN prefers a vehicle with slow speed to be backbone in a road segment, no matter Input: , OP , CP ; Output: NOP, DP; (1) if is a correct data packet then (2) = SOP( ) − OP ; (3) if ∃ ⊆ YP( ) satisfying decoding conditions then (4) obtain original packets SOP( ) by decoding ; (5) NOP = SOP( ) − OP ; (6) while ∃{ , } ⊆ NOP having DIR( ) ̸ = DIR( ) do (7) create a coded packet DP({ , }); (8) send DP({ , }) to +1 and −1 ; (9) send two coded packets using { , } to ; (10) NOP = NOP − { , }; (11) end (12) create coded packets DP(NOP); (13) if DIR(NOP) = 1 then (14) send DP(NOP) to +1 and ; (15) else (16) send DP(NOP) to −1 and ; (17) end (18) end (19) end (20) if is an incorrect data packet then (21) send REQ( ) to ; (22) end (23) if is REQ( ) from node then (24) if is carried by then (25) if ∃ other original packet to be sent to then (26) create one or several coded packets DP({ , }); (27) send DP({ , }) to ; (28) else (29) send to ; (30) end (31) else (32) if DIR( ) = 1 then (33) send REQ( ) to −1 ; (34) else (35) send REQ( ) to +1 ; (36) end (37) end (38) end Algorithm 1: Data coding and forwarding algorithm for primary backbone . how fast other vehicles drive; SFN chooses a vehicle with a speed close to the optimal speed in each segment.…”

.Vehicular networks, as a significant technology in intelligent transportation systems, improve the convenience, efficiency, and safety of driving in smart cities. However, because of the high velocity, the frequent topology change, and the limited bandwidth, it is difficult to efficiently propagate data in vehicular networks. This paper proposes a data dissemination scheme based on fuzzy logic and network coding for vehicular networks, named SFN. It uses fuzzy logic to compute a transmission ability for each vehicle by comprehensively considering the effects of three factors: the velocity change rate, the velocity optimization degree, and the channel quality. Then, two nodes with high abilities are selected as primary backbone and slave backbone in every road segment, which propagate data to other vehicles in this segment and forward them to the backbones in the next segment. The backbone network helps to increase the delivery ratio and avoid invalid transmissions. Additionally, network coding is utilized to reduce transmission overhead and accelerate data retransmission in interbackbone forwarding and intrasegment broadcasting. Experiments show that, compared with existing schemes, SFN has a high delivery ratio and a short dissemination delay, while the backbone network keeps high reliability.
