A bounding algorithm for the broadcast storm problem in mobile ad hoc networks

Abstract-Many protocols used in Mobile Ad Hoc Networks rely on the broadcasting capability, especially when performing a route discovery process. However, an efficient broadcasting protocol should be devised to reduce the unnecessary redundant rebroadcasting at some nodes (redundancy) as well as to increase the coverage area as much as possible (reachability). A few approaches have been developed in the literature. We propose a bounding algorithm which is shown to be an efficient candidate to accommodate the two goals, that is to increase reachability while limiting redundancy

Determining the representative factors affecting warning message dissemination in VANETs

In this paper, we present a statistical analysis based on the 2k factorial methodology to determine the representative factors affecting traffic safety applications in Vehicular ad hoc networks (VANETs). Our purpose is to determine what are the key factors affecting Warning Message Dissemination (WMD) in order to concentrate on such parameters, thus reducing the amount of required simulation time when evaluating VANETs. Simulation results show that the key factors affecting warning messages delivery are: (i) the transmission range, (ii) the radio propagation model used, and (iii) the density of vehicles. Based on this statistical analysis, we evaluate a compound key factor: neighbor density. This factor combines the above-mentioned factors into a single entity, reducing the number of factors that must be taken into account for VANET researchers to evaluate the benefits of their proposals.This work was partially supported by the Ministerio de Educacion y Ciencia, Spain, under Grant TIN2008-06441-C02-01, and by the Fundacion Antonio Gargallo, under Grant 2009/B001.Martínez Domínguez, FJ.; Toh, CK.; Cano Escribá, JC.; Tavares De Araujo Cesariny Calafate, CM.; Manzoni, P.

DrivingStyles: A Mobile Platform for Driving Styles and Fuel Consumption Characterization

[EN] Intelligent transportation systems (ITS) rely on connected vehicle applications to address real-world problems. Research is currently being conducted to support safety, mobility and environmental applications. This paper presents the DrivingStyles architecture, which adopts data mining techniques and neural networks to analyze and generate a classification of driving styles and fuel consumption based on driver characterization. In particular, we have implemented an algorithm that is able to characterize the degree of aggressiveness of each driver. We have also developed a methodology to calculate, in real-time, the consumption and environmental impact of spark ignition and diesel vehicles from a set of variables obtained from the vehicle's electronic control unit (ECU). In this paper, we demonstrate the impact of the driving style on fuel consumption, as well as its correlation with the greenhouse gas emissions generated by each vehicle. Overall, our platform is able to assist drivers in correcting their bad driving habits, while offering helpful tips to improve fuel economy and driving safety.This work was partially supported by the Ministerio de Economía y Competitividad, Programa Estatal de Investigación, Desarrollo e Innovación Orientada a los Retos de la Sociedad, Proyectos I+D+I 2014, Spain, under Grant TEC2014-52690-R.Meseguer Anastasio, JE.; Toh, CK.; Tavares De Araujo Cesariny Calafate, CM.; Cano, J.; Manzoni, P.

The Design Implementation of a Hybrid Handover Protocol for Multi-Media Wireless LANs

Handovers for multi-media Wireless LANs (WLANs) have special requirements, unlike those in the public wireless networks. In this paper, the problems and challenges faced in a multi-media WLAN environment are presented and a multi-tier wireless cell clustering architecture is introduced. New design issues for multi-media handovers are specified and a fast, continuous and efficient hybrid handover protocol is proposed. A prototype of the proposed handover protocol is implemented into a Cambridge Fairisle ATM switch and the results are evaluated. We found that implementing transport mobility for a Wireless ATM environment is not practical as the cell re-routing function is not scalable to increasing cell rate and to the number of mobile connections. It also changes the characteristics of the traffic. Instead, the data link layer mobility implementation is found to work well. The protocol provides symmetric data disruption to traffic flows in both directions and up to seventy five intra-cluster handovers can be supported in a second. Throughout the experiment, cells arrive in sequence with no cell loss observed during the handover, up to the capacity limit of the ATM switch
