Abstract: Roundabouts or traffic cycles reduce the possibilities of accidents and smooth the traffic at road intersections. In order to master the rules of driving around these traffic cycles intensive practicing is required. The more congested the area of the roundabout, the more confused for drivers to drive there. Especially, fresh or exhausted drivers which panic or/and do mistakes while entering, cycling or existing the roundabout. In this work, we aim to introduce a driving assistance protocol to help drivers choosing the best lane to enter the roundabout and the best time to enter or exist the roundabout. The proposed protocol recommends the best reaction of any vehicle regarding the roundabout based on its location, its targeted destination, and the distribution of traffic in the vicinity of the roundabout. Using some experimental scenarios, we evaluate the performance of this protocol in terms of decreasing the percentage of accidents, increasing throughput of the roundabout and decreasing the waiting delay time of vehicles.

Abstract: Recommending traveling vehicles to take a certain path towards their targeted destinations have received great interest recently. At the downtown area several paths can lead to the same located destination, this is due to the grid-layout architecture of modern downtowns. Drivers always wish to reach their destinations as fast as possible and without traveling drastically long distance or without consuming extra fuel. The best path towards any destination is determined based on the relative location of the vehicle from its destination and based on other vehicles traffic distribution on the road network. Although numerous studies have investigated this issue over the road network, the communication failures and their effects on the obtained path have been neglected in those previous studies. In this paper, we investigate these potential faults and their effects on the correctness of the selected paths. We then proposed a new protocol to tackle these potential failures while selecting the best path towards each destination over the road network, fault tolerant path recommendation protocol (FT-PR). From the experimental results, we can see that the FT-PR protocol has a higher success ratio than previous path recommendation protocols, such as ICOD. This is demonstrated by obtaining paths with shorter traveling time and shorter traveling distance. The FT-PR protocol also eliminates extra loops over the road network in each selected path.

Abstract: Drivers change the lane over the road networks is a common seen practice when they face a slow, stopped or broken vehicle. Sometimes they have to change the lane to take the next exist or the next U-turn towards their targeted destination. Changing the lane requires that the driver should be aware of vehicles behind him on the new lane or vehicles intending to change to the same lane during that period of time. If any of these vehicles are located on the blind-spot or if the driver miss-expect that vehicle's location or speed, his attempt of changing the lane can be failed or on some scenarios this may lead to an accident. On highways this type of accident can be fatal due to the high speed vehicles which do not allow drivers to stop the severity situation. This paper presents an Intelligent LAne CHange assistant protocol (ILACH) for highway road scenario. This protocol assists drivers to change the lane safely and efficiently. Several scenarios are considered where a certain driver attempts to change the lane. From the experimental results we can see that the proposed protocol enhances the safety and the efficiency of the tested scenarios.

Research Title: An Adaptive Traffic Energy-Efficient MAC Protocol for Mobile Delay-Tolerant Sensor Networks

Faculty: Information Technology

Abstract: Delay-tolerant sensor networks (DTSNs) require efficient MAC transmission strategies that include energy constraint, relaxed latency, mobility support and diverse traffic load. Reservation-based and contention-based MAC schemes are used to improve throughput and energy consumption. In this paper, we propose a traffic adaptive, energy-efficient MAC protocol to achieve better data transmissions and as energy consumption, in order to satisfy the requirements in DTSN. In our protocol, reservation and contention modes are adjustable, in order to adapt to the traffic load with a suitable duty cycle length for achieving energy efficiency. The simulation results of our protocol demonstrate better performance in terms of energy efficiency and traffic adaptability than the schedule-based MAC protocol TDMA, the contention-based protocol CSMA, and the traffic adaptive protocol TRAMA under mobile DTSN environments.

Research Title: Traffic Efficiency Protocol for Highway Roads in Vehicular Network

Abstract: Vehicular Ad-hoc Networks (VANETs) technology has been utilized in recent applications to enhance the traffic fluency over the road network. Various types of emergency cases may negatively affect the efficiency of traffic flow in highway road scenarios, including accidents, damaged vehicles or the presence of emergency vehicles. These cases exaggerate the traffic problems in severe congestion scenarios. In this paper, we propose a traffic efficiency protocol which first aims to detect emergency cases over highway road scenarios. Then, it recommends the most appropriate response for each vehicle affected by the detected emergency case. The best response for each vehicle is determined based on the vehicle's location and speed. Our protocol also considers overall traffic conditions over the investigated road scenario. From the experimental results, we can prove that our proposed protocol has increased traffic fluency in the vicinity of emergency cases over highway road scenarios. Moreover, it has increased safety conditions for vehicles in such scenarios.

Research Title: Context-aware traffic light self-scheduling algorithm for intelligent transportation systems

Abstract: Traffic lights are located on the road intersections to control and manage the competing traffic flows. Several algorithms have been proposed considering the real-time traffic characteristics of each competing traffic flow at the road intersection. Emergency vehicles such as ambulance, fire truck and police vans should have higher priorities to cross any road intersection first. Whenever an emergency vehicle appears close to any road intersection, all vehicles on the competing flows should stop and allow that vehicle to proceed first. However, this may cause a hazards situation in the case that any driver miss-behaves or insists to follow the current traffic light phase. In this paper, we aim at designing a context-aware traffic light self-scheduling (CA-TLS) algorithm. This algorithm uses the traffic characteristics of the traffic flows and the emergency vehicles presence on the competing flows at any signalized road intersection. First, these parameters are gathered using periodic advertisement messages of traveling vehicles. Then, the CA-TLS algorithm sets the phases of each traffic light cycle according to the traffic gathered data. The green phase of any traffic flow can be interrupted to enable the fast proceeding of the appeared emergency vehicles. An extensive set of experiments have shown that this algorithm decreases the delay time of emergency vehicles at the signalized road intersections.

Abstract: Several traffic evaluation and congestion detection protocols have been proposed in the literature for the vehicular networks. These protocols gather and analyze the basic traffic data of all traveling vehicles at each area of interest to obtain the vehicular traffic evaluations. All vehicles should be equipped by wireless transceiver in order to send and receive the packets of their traffic data individually. In general, the accuracy of typical traffic evaluation protocols depends mainly on the correctness and the quantity of the gathered data. In this paper, we propose an intelligent vehicular traffic prediction protocol (ITP) that estimates the traffic characteristics of each road segment in urban areas. ITP requires the basic traffic data of only some vehicles traveling on the investigated road segment. It then uses the gathered data to predict traffic characteristics of that road segment. The paper also investigates the minimum number vehicles that should participate broadcasting their data in order to obtain accurate traffic evaluation of the investigated road segment. From the experimental results, we can infer that the ITP protocol predicts an accurate level of the traffic evaluation when 25% of the traveling vehicles or more are equipped by wireless transceivers.

Abstract: One of the most attractive features of the Hex-Cell HC (d) topology is the fact that it has an embedding capability of other topological structures. In this paper, we propose some algorithms for mapping linear array, ring, mesh (2D array), binary tree and multi 3D hypercube topology onto the HC (d) topology. Then, we compute the dilation, congestion and the expansion of each mapping algorithm to measure that algorithm efficiency.

Abstract: The traffic over the downtown areas have been incredibly increasing. This prevents many drivers from reaching their targeted destinations on time. This issue becomes more severe in multi-destinations trips, when the driver plan to visit several destinations during the same trip and face un-expected traffic that causes severe delay. In these scenarios, drivers end up canceling some destinations or wasting long exhausted time on the trip. Efficiently planning the multi-destinations trips helps drivers to reach their destinations successfully and estimate the required time of the entire trip. This paper presents a multi-destinations trip planner protocol. The proposed protocol mainly considers the relative locations of the targeted destinations and the traffic characteristics over the road network. A set of simulated experiments have been used to test the performance of this protocol in round trip scenarios

Abstract: Protein homeostasis is tightly regulated by the ubiquitin proteasome pathway. Disruption of this pathway gives rise to a host of neurological disorders. Through whole exome sequencing (WES) in families with neurodevelopmental disorders, we identified mutations in PSMD12, a core component of the proteasome, underlying a neurodevelopmental disorder with intellectual disability (ID) and features of autism spectrum disorder (ASD). We performed WES on six affected siblings from a multiplex family with ID and autistic features, the affected father, and two unaffected mothers, and a trio from a simplex family with one affected child with ID and periventricular nodular heterotopia. We identified an inherited heterozygous nonsense mutation in PSMD12 (NM_002816: c.367C>T: p.R123X) in the multiplex family and a de novo nonsense mutation in the same gene (NM_002816: c.601C>T: p.R201X) in the simplex family …
