“…In this section, we generate the mobile nodes on the ONE simulator (The ONE) and evaluate the performance of our NC/CTE method in contrast with Epidemic (Vahdat and Becker, 2000), PRoPHET (Lindgren et al, 2003), TBNC (Li et al, 2013) and generic Wi-Fi.…”

“…In our former work (Li et al, 2013), the trajectories of mobile nodes are computed in a central manager server. As the number of nodes or the speed of the nodes increase, the processing time in the server will get longer, and the trajectory estimation will not be accurate because the result of the calculation is late in contrast to the movement of nodes.…”

“…Overhead packets will be quenched in this method. In our former work (Li et al, 2013), we try to use the GPS navigation data of nodes to forward packets. However, there are still two unsolved problems in former researches: (1) There are too heavy loads on the central sever to estimate the dynamic topology of networks.…”

“…Nguyen et al [14] showed the advantage of the proposed XORs coding scheme over the traditional wireless broadcast in the bandwidth efficiency through simulation and theoretical analysis. Network coding is also used in mobile wireless sensor network [15] to adapt for the dynamics velocity of mobile nodes. However, all the above algorithms cannot be used in wireless sensor network, because they did not consider sleep scheduling.…”

In wireless sensor networks (WSNs), wireless links are unreliable and sensor nodes may be in sleep mode. Thus, many applications which require reliable broadcast cannot work properly if they lost some packets. In order to make sure every sensor node in the network receives all packets completely and correctly, retransmission of lost packets is indispensable. Many retransmission methods with network coding have been proposed but they do not catch coding opportunity. In this paper, real-time retransmission algorithm based on network coding (NCRR) is proposed to make the average number of transmissions as less as possible. During the transmission of original packets, we detect whether a certain time slot is suitable for retransmitting a coded packet based on recovery ratio. We analyze the number of transmissions with traditional retransmission and with network coding. Compared with existing approaches, simulation results show that our algorithm can effectively reduce the average number of transmissions and improve the transmission efficiency.

“…Furthermore, Francesca Cuomo propose a high throughput dissemination scheme for VANET based on the dynamic formation of a multi-hop backbone network in [6], he describe and analyze such a networking protocol when used to broadcast message flows generated by a Road Side Unit along a linear road, forming a VANET structure that is identified as a Vehicular Backbone Network (VBN). In [7], Lingzhi Li present a trajectorybased network coding (TBNC) method to disseminate data in Mobile Wireless sensor network (MWSN), and the experiments show that TBNC is able to reduce overhead messages, and enhance the reliability of transmission.…”

Emergency warning message (EWM) transmission insurance is one of the most interesting topics for Vehicular Cyber-physical System (V-CPS) application. A relatively low transmission requirement should improve EWM's real-time delivery, and however, decrease reliability of packet delivery by its corresponding burst converge-cast, especially under multihop condition. In this paper, based on a series experiments, a clear channel assessment (CCA) threshold ladder selection method is proposed to ensure both real-time and reliability for EWM transmission. The experimental results show that the threshold adjusting method has a positive effect on the delivery rate. With an appropriately diminishing clear channel assessment threshold related to the packet hops, the global dissemination successful rate can be up to 73.5%, and more than 90% of the 1-hop nodes can receive the correct packet. The experiment results provide a practicable method to improve EWM dissemination performance. Index Terms-Inter-vehicle communication, emergency warning message, clear channel assessment, delivery ratio, ladder CCA threshold selection mechanism I. INTRODUCTION With close to a billion vehicles on the road today, and a doubling project over the next 20 years, we face pressing challenges about how to improve efficiency and reliability for the vehicle network to meet vehicle driver's demands in real time collision avoidance. As a result, Vehicular Cyber-Physical System (V-CPS) is put forward to monitor the road conditions via the inter-vehicle communication (IVC) mode. All the road vehicles in object region are considered as nodes, which communicate with each other via Vehicular Ad-Hoc Networks (VANETs). The key point we are interested in this paper is how to ensure the emergency warning message (EWM) delivery in VANETs. To ensure EWM transmission quality, IEEE recently drafted 802.11p/WAVE (Wireless Access in Vehicular Environments) standard, which introduces CCH (common control channel) to disseminate control and warning messages[1]. Vehicles switch their working channel between CCH and SCH (service channel), which used to exchange non-safety-related data in turn.
