“…The basic concept of MPECS was to split the whole region into separate areas by the Voronoi graph; in order to enable each vehicle to estimate its lifetime and cost of becoming the cluster head in its current location. The proposed technique has shown evidence of significant MPECS capabilities enhance clustering design reliability with reduced overhead, finally, in [54]. This study suggested a modern scheme of data distribution focused on clustering and CBD.…”

“…To avoid unwanted propagation, which can also trigger the issue of the transmitted hurricane, the time barrier methods are modified in order to resolve the problem. While in [54], a modern, efficient clustering simulation versatility (MPECS) system was proposed.

Vehicular ad-hoc network (VANET), identified as a mobile ad hoc network MANETs with several added constraints. Basically, in VANETs, the network is established on the fly based on the availability of vehicles on roads and supporting infrastructures along the roads, such as base stations. Vehicles and road-side infrastructures are required to provide communication facilities, particularly when enough vehicles are not available on the roads for effective communication. VANETs are crucial for providing a wide range of safety and non-safety applications to road users. However, the specific fundamental problem in VANET is the challenge of creating effective communication between two fast-moving vehicles. Therefore, message routing is an issue for many safety and non-safety of VANETs applications. The challenge in designing a robust but reliable message dissemination technique is primarily due to the stringent QoS requirements of the VANETs safety applications. This paper investigated various methods and conducted literature on an idea to develop a model for efficient and reliable message dissemination routing techniques in VANET.

“…In this section, we evaluated the proposed mechanism using OMNeT++ [43], simulation of urban mobility (SUMO) [27] and Veins [40] platform. The proposed algorithm is compared to clustering based probabilistic broadcasting (CPB) [30], cluster-based EM dissemination proposed by Jin et al (termed as Jin Model) [23] and simple flooding. In CPB, data is disseminated using probabilistic forwarding, and the CH is responsible for dissemination of messages.…”

Time Barrier-Based Emergency Message Dissemination in Vehicular Ad-hoc Networks

With the advancement in technology and inception of smart vehicles and smart cities, every vehicle can communicate with the other vehicles either directly or through ad-hoc networks. Therefore, such platforms can be utilized to disseminate time-critical information. However, in an ad-hoc situation, information coverage can be restricted in situations, where no relay vehicle is available. Moreover, the critical information must be delivered within a specific period of time; therefore, timely message dissemination is extremely important. The existing data dissemination techniques in VANETs generate a large number of messages through techniques such as broadcast or partial broadcast. Thus, the techniques based on broadcast schemes can cause congestion as all the recipients re-broadcast the message and vehicles receive multiple copies of same messages. Further, re-broadcast can degrade the coverage delivery ratio due to channel congestion. Moreover, the traditional cluster-based approach cannot work efficiently. As clustering schemes add additional delays due to communication with cluster head only. In this paper, we propose a data dissemination technique using a time barrier mechanism to reduce the overhead of messages that can clutter the network. The proposed solution is based on the concept of a super-node to timely disseminate the messages. Moreover, to avoid unnecessary broadcast which can also cause the broadcast storm problem, the time barrier technique is adapted to handle this problem. Thus, only the farthest vehicle rebroadcasts the message which can cover more distance. Therefore, the message can reach the farthest node in less time and thus, improves the coverage and reduces the delay. The proposed scheme is compared with traditional probabilistic approaches. The evaluation section shows the reduction in message overhead, transmission delay, improved coverage, and packet delivery ratio.

“…Therefore, how to select an appropriate area to achieve effective data dissemination is more important. Although, there are many researches about the issue [1] [2] [3] and a lot of novel schemes are proposed [4] [5], they usually consider the location of event as the dissemination area. This leads to more control packets and delay time when vehicles do not know the dissemination area or need multiple event informations at the same time.…”

Extended AbstractWith the rapid development of wireless technologies, vehicular ad hoc networks (VANETs) attract people's attention in recent years. VANETs consist of vehicles and some facilities which are deployed on the road sides. And each vehicle equips wireless communication devices to communicate with other vehicles and facilities. VANETs support a wide range of applications and have been extensively studied. Data dissemination is an important issue in VANETs. However, in order to avoid packet flooding, data usually be disseminated in some specific areas. Therefore, how to select an appropriate area to achieve effective data dissemination is more important. Although, there are many researches about the issueand a lot of novel schemes are proposed [4] [5], they usually consider the location of event as the dissemination area. This leads to more control packets and delay time when vehicles do not know the dissemination area or need multiple event informations at the same time.In this paper, we propose an efficient data dissemination in urban vehicular ad hoc networks which has better success ratio of data requests and less control packets. First, find an appropriate dissemination area and spread the information of events over the area. We select the intersection with the maximum traffic flow as the center of dissemination area. The size of the area is determined by the importance of events which are classified into three levels. The events with higher level are more important. The dissemination area of i-th level events is bounded by the intersections which are (i-1)-hop far from the center. Secondly, choose a path to query the event information and a path to return the data quickly. The request packet will be sent to the dissemination area by a shortest path. The first vehicle received the packet will reply the data according to the trajectory of vehicle that issued the request packet. In addition, due to the mobility of vehicles, we also present some mechanisms to ensure the delivery efficiently. Finally, we use Network Simulator 2.35 (NS2) to build simulation environments and compare the proposed method with CDN and CDNY [4]. The simulation results show that the proposed method outperforms CDN and CDNY in terms of the control packets, the delay and the packet delivery ratio. References[1] W.
