  • A Scalable Bandwidth-Efficient Hybrid Adaptive Service Discovery Protocol for Vehicular Networks with Infrastructure Support
    IEEE Transactions on Mobile Computing, 2014
    Co-Authors: Kaouther Abrougui, Richard W Pazzi, Azzedine Boukerche, Mohammed Almulla
    Abstract:

    In recent years, we have witnessed a growing interest in Vehicular Networks from both the research community and industry. Several potential applications of Vehicular Networks are envisioned such as road safety and security, streaming Services, traffic monitoring and driving comfort, just to mention a few. It is critical that the existence of convenience or driving comfort Services do not negatively affect the performance of safety Services. In essence, the dissemination of safety Services or the Discovery of convenience applications require the communication among Service providers and Service requesters through constrained bandwidth resources. Therefore, Service Discovery techniques for vehicular networks must efficiently use the available common resources. In this paper, we present a bandwidth-efficient and scalable hybrid adaptive Service Discovery Protocol (VSDP) for Vehicular Networks. VSDP aims at providing high success ratio while guaranteeing low response time and good scalability when the number of requests increases. Our proposed Protocol finds the Service provider and its routing information simultaneously which results in overall bandwidth savings. It uses diverse channels to exchange Discovery and routing packets, thereby decreasing the congestion on single channels and decreasing the delay of Service Discovery. Our proposed Service Discovery Protocol adapts the advertisement zone size of Service providers based on an efficient adaptation mechanism that takes into consideration network condition and application requirements. The adaptation process is based on an adjustment technique and a prediction technique. We discuss the implementation of our Protocol, present its proof of correctness as well as the performance evaluation through an extensive set of simulation experiments and using different mobility models. Our results show the scalability of our Protocol. They indicate that our techniques can achieve significant success rate (more than 90 percent), while guaranteeing low response time (in the order of milliseconds) and low bandwidth usage when compared to existing Service Discovery techniques.

  • performance evaluation of an efficient fault tolerant Service Discovery Protocol for vehicular networks
    Journal of Network and Computer Applications, 2012
    Co-Authors: Kaouther Abrougui, Azzedine Boukerche, Hussam Soliman M Ramadan
    Abstract:

    Recently, vehicular networks and inter-vehicle communication have received attention from the research community and the automotive industry. In this context, many Services are deployed in vehicular networks that are beneficial to drivers and passengers. Service Discovery in vehicular networks is vital to make such Services useful. However, due to the lack of communication reliability in vehicular ad hoc networks, it is necessary to implement fault-tolerant techniques during the Discovery of Service providers in vehicular networks. Very few Service Discovery Protocols for vehicular networks have considered fault tolerant techniques, which are very important for the efficiency of Service Discovery. Fault tolerant techniques improve Service request satisfaction and reduce dropped connections due to faulty components between the Service provider and the Service requester. In this paper, we propose a fault tolerant location based Service Discovery Protocol for vehicular networks which can work well under Service provider failures, communication link failures and roadside router failures. Our Protocol permits the Discovery of location based Services where the requester specifies the region of interest within the request. Our Protocol uses an infrastructure support consisting of clusters of roadside routers formed in specific regions in the vehicular network. In addition, Service Discovery messages are integrated into the network layer and use channel diversity in order to improve Service Discovery efficiency. We describe our fault tolerant location based vehicular Service Discovery Protocol (FTLocVSDP) and discuss its proof of correctness and performance evaluation. We prove that the success rate is improved in the roadside router failure and in the communication link failure scenarios by 50% and 30%, respectively, compared to the location based Service Discovery Protocol for vehicular networks (LocVSDP) which does not consider fault tolerant techniques.

  • Efficient load balancing and QoS-based location aware Service Discovery Protocol for vehicular ad hoc networks
    EURASIP Journal on Wireless Communications and Networking, 2012
    Co-Authors: Kaouther Abrougui, Azzedine Boukerche, Hussam Ramadan
    Abstract:

    Service Discovery studies in vehicular networks that guarantee QoS requirements to Service requesters are very important. To the best of authors' knowledge, none of the existing Service Discovery Protocols in vehicular networks have been provided in the literature that guarantee QoS to Service requesters and to the vehicular network. For efficient Service Discovery in vehicular networks, it is very important to provide users with Services that suit better to their requests while balancing the load on Service providers. Moreover, for Service Discovery Protocol integrated with routing Protocols, it is important to guarantee load balancing on routing paths between Service providers and Service requesters. In this article, we present a QoS aware location-based Service Discovery Protocol for vehicular networks. Our Protocol guarantees load balancing on Service providers, and routing paths between Service providers and Service requesters. It permits also to choose Service providers and routing paths between Service providers and Service requesters that satisfy some performance attributes specified by Service requesters. We present our QoS aware Protocol, prove its correctness, report on its performance evaluation, and discuss our experimental results we have obtained using realistic scenarios.

  • secure Service Discovery Protocol for intelligent transport systems proof of correctness
    Design and Analysis of Intelligent Vehicular Networks and Applications, 2011
    Co-Authors: Kaouther Abrougui, Azzedine Boukerche
    Abstract:

    Intelligent Transportation Systems (ITS) have attracted many researchers that invested a lot of effort to develop many applications mainly for vehicular systems. Existing and investigated applications in vehicular systems are classified in two folds: safety applications and convenience applications. The first type of applications focuses mainly on drivers security and safety on the roads by providing warnings and alerts if there are accidents or disasters. The second type of applications helps drivers and passengers to localize Services, get accurate weather or road condition information, get entertainment access, or even interact with surrounding Services. Thus, a secure Service Discovery and communication Protocol is mandatory in order to prevent from many attacks and malicious processes in the vehicular system. An efficient Service Discovery Protocol should guarantee a secure Discovery and communication in the vehicular system while maintaining the network scalability and a low communication delay. In this paper, we present the possible attacks that can happen at the Discovery level and at the routing level. Then, we present our secure Service Discovery Protocol for vehicular systems designed for the convenience type of applications. We prove the correctness of our proposed scheme and we compute its message complexity.

  • GLOBECOM - An Efficient Fault Tolerant Location Based Service Discovery Protocol for Vehicular Networks
    2010 IEEE Global Telecommunications Conference GLOBECOM 2010, 2010
    Co-Authors: Kaouther Abrougui, Azzedine Boukerche, Richard W Pazzi
    Abstract:

    Recent studies on Service Discovery Protocols in vehicular networks have shown promising results. However, very little work has been reported on how to integrate the fault tolerance feature into these mechanisms. This feature is vital for the success of the deployment of Service Discovery Protocols in vehicular networks. Drivers on their cars should not have their requests dissatisfied or their connections dropped because a Service provider or some components between the Service provider and the Service requester have failed. In this paper, we present a fault tolerant location based Service Discovery Protocol for Vehicular Networks. The main advantages of our Protocol is its ability to tolerate Service providers failure, communication links failure and roadside routers failure. We present our fault tolerant Protocol, and report on its performance evaluation. Our simulation experiments show that our proposed fault tolerant LocVSDP algorithm improves the success rate significantly over the basic LocVSDP. In fact, the success rate is improved in the roadside routers failures scenario and in the links failures scenarios by 50 percent and 30 percent respectively.

  • Context-aware and location-based Service Discovery Protocol for Vehicular Networks: Proof of correctness
    IEEE Local Computer Network Conference, 2010
    Co-Authors: Kaouther Abrougui, Azzedine Boukerche, Richard W Pazzi
    Abstract:

    Recent advances in Intelligent Transportation Systems (ITS) and the growing number of applications in Vehicular Networks (VN) have attracted many researchers. Applications in Vehicular Networks comprise but are not limited to safety applications and convenience applications. Deploying Vehicular Networks widely cannot be accomplished without overcoming the existing research challenges in such networks. Service Discovery is one of the main challenges in Vehicular Networks which are characterized by their large scale and high mobility. Existing Service Discovery techniques for ad hoc networks cannot be applied directly to Vehicular Networks scenarios due to their poor performance and decreased efficiency in Vehicular Networks. In this paper, we present our location-based Service Discovery Protocol for Vehicular Networks (LocVSDP). Our Protocol permits the Discovery of location-aware and time-sensitive Services in Vehicular Networks. Moreover, our LocVSDP Protocol improves Service Discovery efficiency by integrating Service information into the network layer and using diverse channels. In our Protocol, we present our efficient mechanism that permits to Service requesters to find Service providers and their routing information simultaneously, which results in overall bandwidth savings. We make use of diverse channels for the exchange of Discovery and routing packets, which decreases the congestion on single channels and improves the delay of Service Discovery. Then, we present our efficient location-based request propagation and an efficient computation of the Service reply, based on the specified location of the requested Service in the drivers request. We discuss the implementation of our Protocol and present its proof of correctness.

  • context aware and location based Service Discovery Protocol for vehicular networks
    Performance Evaluation of Wireless Ad Hoc Sensor and Ubiquitous Networks, 2009
    Co-Authors: Azzedine Boukerche, Kaouther Abrougui, Richard W Pazzi
    Abstract:

    Vehicular Networks (VN) have attracted recent attention from researchers mainly motivated by the potential applications that will leverage Intelligent Transportation Systems (ITS). Such applications include road safety and security, traffic monitoring and driving comfort. However, several research challenges must be overcome before Vehicular Networks can be wide deployed. One of these challenges comprises how vehicles and Service providers could discover each other in a Vehicular Networks, which is well-known for its large scale and high-mobility nature. Therefore, existing Service Discovery techniques for low-mobility or wired networks cannot be applied directly to Vehicular Networks. Most Service Discovery strategies available present high overhead and poor performance in a Vehicular Network scenario. In this paper, we propose a context-aware and location-based Service Discovery Protocol for next generation Vehicular Networks (LocVSDP). Our Protocol offers a scalable framework for the Discovery of time-sensitive and location based Services in Vehicular Networks. Furthermore, LocVSDP is integrated into the network layer and uses channel diversity for improved Service Discovery efficiency. We discuss the implementation of our Protocol and compare the message and time complexities of our Protocol with the existing location-based Service Discovery Protocol VITP. Our results indicate that our techniques outperform the VITP Protocol in terms of message and time complexities.

  • COMPSAC (2) - Property-Based Peer Trust in the Sleeper Service Discovery Protocol
    30th Annual International Computer Software and Applications Conference (COMPSAC'06), 2006
    Co-Authors: J. Buford, E. Celebi, P. Frankl
    Abstract:

    We describe the use of property-based peer trust to provide security in Sleeper, a new energy-efficient Service Discovery Protocol which uses proxied advertisement and Discovery to dynamically offload Service Discovery workload from power-limited devices. Property-based digital certificates have previously been used in trust-negotiation methods. In earlier work we developed a new method for secure and private peer-to-peer trust negotiation using property-based digital certificates and a secure trust negotiation agent. Here we describe how property-based peer trust can be used to secure the Sleeper Service Discovery Protocol

  • Sleeper: A Power-Conserving Service Discovery Protocol
    2006 3rd Annual International Conference on Mobile and Ubiquitous Systems - Workshops, 2006
    Co-Authors: J. Buford, E. Celebi, B. Burg, P. Frankl
    Abstract:

    The design of Service Discovery Protocols which limit power consumption of devices has received little consideration but is an important problem because of the growing use of power-limited mobile networked devices. We describe sleeper, a new Discovery Protocol which uses proxied advertisement and Discovery to dynamically offload Service Discovery workload from power-limited devices. The advertisement structure supports several modes of Service Discovery including conventional Service advertisements, meta Discovery, taxonomic-based Discovery, location-based Discovery and federated Discovery. In addition, sleeper supports both push and pull modes of advertisement, but unlike other Protocols uses Service popularity to select push or pull modality. We describe an implementation of the new Protocol and provide an analytical model for comparing response time to other push-based Service Discovery methods
