    SMART: Secure Multi-pAths Routing for wireless sensor neTworks
    (CERIST, 2014-06-22) Lasla, Noureddine; Derhab, Abdelouahid; Ouadjaout, Abdelraouf; Bagaa, Miloud; Challal, Yacine
    Abstract. In this paper, we propose a novel secure routing protocol named Secure two-hop disjoint Multi-pAths Routing for wireless sensor neTworks (SMART) as well as its underlying key management scheme named Extended Two-hop Keys Establishment (ETKE). The proposed framework keeps consistent routing topology by protecting the hop count information from being forged. The two-hop scheme ensures immediate verification and fast detection of inconsistent routing information with- out referring to the sink node. We prove that it is sufficient to keep only two-hop disjoint paths to ensure full-resilience against node capture attacks. We have demonstrated through simulations that our solution outperforms a comparative solution in literature. In addition, ETKE is more resilient to node capture attacks than the probabilistic key man- agement schemes.

    Securing Distance Vector Routing Protocols for Hybrid Wireless Mish Networks
    (CERIST, 2010-04) Babakhouya, Abdelaziz; Challal, Yacine; Bouabdallah, Abdelmadjid; Gharout, Said
    Hybrid Wireless Mesh Networks (HWMNs) are currently emerging as a promising technology for a wide range of applications such as public safety, emergency response, and disaster recovery operations. HWMNs combine the concepts of mesh networks and ad hoc networks to maintain network connectivity. Routing is essential for HWMN in order to discover the network topology and built routes. The problem of all the current ad hoc routing protocols is that they trust all nodes and assume that they behave properly; therefore they are more vulnerable to nodes misbehavior. Misbehaving nodes can advertise incorrect routing information and disturb the topology building process. This attack is difficult to detect in distance vector routing protocols since nodes have no information regarding the network topology beyond the immediate neighbors. In this paper we propose a Consistency Check protocol for Distance Vector routing in HWMN environment. Our Consistency Check protocol can detect and reject false routes under the assumption that some mesh routers are trusted and do not cheat. Trough security analysis and simulation, we show that our approach is resilient to false accusation attacks while inducing an acceptable routing overhead.

    A survey on Wireless Sensor Networks for Urban Traffic Monitoring: Applications and Architectures
    (CERIST, 2012) Kafi, Mohamed Amine; Badache, Nadjib; Challal, Yacine; Bouabdallah, Abdelmadjid; Djenouri, Djamel
    Vehicular traffic is increasing around the world, especially in urban areas. This increase results in a huge traffic congestion, which has dramatic consequences on economy, human health, and environment. Traditional methods used for traffic management, surveillance and control become inefficient in terms of performance, cost, maintenance, and support, with the increased traffic. Wireless sensor networking (WSN) is an emergent technology with an effective potential to overcome these difficulties, which will have a great added value to intelligent transportation systems (ITS). This technology enables a new broad range of smart city applications around urban sensing. This includes a variety of applications such as traffic safety, traffic congestion control, road state monitoring, vehicular safety warning services, and parking lots management. In this survey, a review on traffic management projects and solutions is provided. The architectural and engineering challenges are discussed, and some future trends are highlighted.

    A study of Wireless Sensor Network Architectures and Projects for Traffic Light Monitoring
    (CERIST, 2012) Kafi, Mohamed Amine; Badache, Nadjib; Challal, Yacine; Bouabdallah, Abdelmadjid; Djenouri, Djamel

Wireless Sensor Networks (WSN) is an emergent technology with an effective potential to overcome these difficulties, and will have a great added value to intelligent transportation systems (ITS) overall. In this survey, we review traffic light projects and solutions. We discuss their architectural and engineering challenges, and shed some light on the future trends as well.
