On the Application of Zone Flooding in a Traffic Warning System On the Applization of Zone Flooding in a Traffic Warning System

چکیده
The LIWAS Traffic Warning System aims at providing early warning to vehicles about slippery conditions on the road. The LIWAS system is currently under development and consists of two main parts: sensors for measuring and classifying the state of the road, and a communication infrastructure for distributing road-state information to vehicles. This paper concentrates on the communication infrastructure, and considers the application of zone flooding for implementing the distribution of road-state information. Zone flooding combines flooding and geocasting to distribute road-state information in a geographically bounded area. To evaluate the applicability of zone flooding in the LIWAS system, a simulation model has been created using the Network Simulator 2. The simulation model captures a representative road-scenario and has been used to evaluate several flooding protocols when used to implement zone flooding. The primary evaluation criteria are the load on the network and the capability to warn other vehicles in time.

متن کاملDetecting Denial of Service Message Flooding Attacks in SIP based Services
Increasing the popularity of SIP based services (VoIP, IPTV, IMS infrastructure) lead to concerns about its security. The main signaling protocol of next generation networks and VoIP systems is Session Initiation Protocol (SIP). Inherent vulnerabilities of SIP, misconfiguration of its related components and also its implementation deficiencies cause some security concerns in SIP based infra...
متن کاملApplication of multi-criteria decision making to estimate the potential of flooding
Integrating a geographic information system and multi-criteria decision making methods have been lead to provide spatial multi-criteria decision making methods. In this study, the spatial potential of flooding was determined based on analytic network process and analytic hierarchy process. At first, six factors of flooding were determined as criteria. The criteria were the slope, hill-slope asp...

The preceding critical points have motivated a lot of interest in developing applications with DSRC technology to improve safety and mobility of traffic on U.S. highways (3–11). Recently, a remote collision avoidance system using DSRC-based V2V communication was verified (8). Similarly, a DSRC-based secure communication protocol for a vehicle ad hoc network has been proposed by exchanging warni...
متن کاملEvaluating the Application of a Financial Early Warning System in the Iranian Banking System
One of the significant problems of banks and investors in Iran is the lack of precise awareness about the financial performance of each bank and the roadmap for improving the conditions. Besides, the undesirable status of the financial performance of banks becomes evident only when the improvement of conditions is complicated. In this paper, a data mining-based early warning system (EWS) model ...
