Information dissemination in inter-vehicle communication is a main way to propagate and obtain the communicating messages among vehicles and infrastructures of road networks in vehicular ad-hoc network (VANET). However, a well-designed protocol for information dissemination would probably provide the higher performance of information dissemination in VANET. In this paper, we propose the improved information dissemination schemes for multi-hop broadcasting in VANET. Our proposed scheme will select a better message forwarder to forward the messages to its neighboring vehicles according to the back-off time for reducing the waiting time in the directional broadcasting. It will also adopt the road-side unit to keep the disseminated message at the intersection of the roads for waiting to disseminate the messages when the vehicle is crossing the intersection which may probably act as a message forwarder to forward the disseminated messages to the intersectional direction. In our simulation, the result indicates that our proposed scheme can efficiently disseminate the messages under the consideration of back-off time in VANET.

Application Fields

A vehicular ad hoc network (VANET) is a mobile ad hoc network that allows wireless communication between vehicles, as well as between vehicles and roadside equipment. Communication between vehicles promotes safety and reliability, and can be a source of entertainment. We investigated the historical development, characteristics, and application fields of VANET and briefly introduced them in this study. Advantages and disadvantages were discussed based on our analysis and comparison of various classes of MAC and routing protocols applied to VANET. Ideas and breakthrough directions for inter-vehicle communication designs were proposed based on the characteristics of VANET. This article also illustrates physical, MAC, and network layer in details which represent the three layers of VANET. The main works of the active research institute on VANET were introduced to help researchers track related advanced research achievements on the subject.

Vehicular ad-hoc network (VANET) is a technology that allows ubiquitous mobility to mobile users. Inter-vehicle communication is an integral component of intelligent transportation systems that enables a wide variety of applications where vehicles interact and cooperate with each other, from safety applications to non-safety applications. VANETs applications have different needs (e.g., latency, reliability, delivery priorities, etc.) in terms of delivery effectiveness. In the last decade, named data networking (NDN) gained the attention of the research community for effective content retrieval and dissemination in mobile environments such as VANETs. In NDN, the content’s name has a vital role in storing and retrieving the content effectively and efficiently. In NDN-based VANETs, adaptive content dissemination solutions must be introduced that can make decisions related to forwarding, cache management, etc., based on context information represented by a content name. In this context, our main contributions are two-fold: (i) we present the hierarchical context-aware content-naming (CACN) scheme for NDN-based VANETs that enables naming the safety and non-safety applications, and (ii) we present a decentralized context-aware notification (DCN) protocol that broadcasts event notification information for awareness within the application-based geographical area. Simulation results show that the proposed DCN protocol succeeds in achieving reduced transmissions, bandwidth, and energy compared to existing critical contents dissemination protocols.

Vehicular Ad hoc network(VANET) are special type of Mobile Adhoc Networks(MANET) where wireless equipped vehicles from a network are continuously travelling along the road. Node movement feature of Vehicular ad hoc network (VANET) closely resembles with that of mobile ad hoc network (MANET) but its high speed mobility and unpredictable movement characteristics are the key contrasting feature from that of MANET. The similarity nature suggests that the prevailing routing protocol of MANET is very much applicable to VANET. However, on the same line, the dissimilarity characteristics result in frequent loss of connectivity. In VANET, topology changes rapidly and there is frequent disconnection which makes it difficult to design an efficient routing protocol for routing data among vehicles called vehicle to vehicle communication. Many routing protocols where implemented like AODV, AOMDV, SD-AOMDV, DSDV, CBDRP. SD-AOMDV adds the speed and direction as two mobility parameter. By enhancing the performance of SDAOMDV routing protocol, packet delivery ratio, and throughput can be increased and end-to-end delay can be reduce.

Vehicular Ad hoc Network (VANET) merupakan konsep subset dari Mobile Ad hoc Networks (MANET) sebagai teknologi yang memungkinkan komunikasi Inter Vehicle Communication (IVC) dan Roadside-toVehicle (RVC).VANET dikarakteristikkan dengan membangun jaringan ad hoc yang dibentuk dari nodenode berupa kendaraan bermobilitas tinggi yang dibatasi dengan aturan lalu lintas sehingga pergerakannya disesuaikan dengan pola tertentu, tidak seperti MANET yang pergerakannya bisa random tanpa ada batasan. Dengan demikian, protokol routing konvensional berbasis topologi pada MANET dinilai tidak cocok untuk VANET. Protokol routing berbasis posisi sepeti GPSR dan GyTAR dinilai cocok untuk VANET. Hal ini tak lain karena aspek dinamika topologi pada VANET yang dapat berdampak nyata pada analisis protokol routing. Dari hasil simulasi diperoleh bahwa GyTAR unggul pada skenario lingkungan perkotaan dilihat dari seluruh parameter end-to-end delay, packet delivery ratio, packet loss dan normalized routing overhead yang lebih baik dari GPSR dengan rata-rata nilai masing-masing, yakni 2,294 ms, 0,958, 4,19%, dan 0,482. Sementara pada skenario lingkungan jalan tol GPSR lebih unggul dibandingkan GyTAR dengan rata-rata nilai end-to-end delay, packet delivery ratio, dan packet loss sebesar 2,639 ms, 0,920, dan 7,923%; namun dengan perolehan NRO yang lebih kecil oleh GyTAR, yakni sebesar 1,725.Kata Kunci: VANET, MANET , GPSR, GyTAR, IVC, SUMO
