  • A Survey of Trajectory Based Data Forwarding Schemes For Vehicular Ad-Hoc Networks
    HAFI Houda and Merniz Salah,Abdelhamid Mehri University,Algeria.
    Many studies demonstrated that routing protocols of MANETs are not suitable for VANETs [15], [20], [6]; the main reason relies on high mobility that causes a rapid topology change that leads to partitioning and routing link failure issues [4]. Adaptable existing schemes also demonstrated a poor network performance, especially when the network density increases. The alternative is to develop new efficient routing schemes for VANETs. Trajectory based routing where the packet is forwarded from the source to the destination based only on vehicle’s trajectory information constitutes one class of forwarding protocols that are proposed for VANETs. This paper surveys such class of protocols, with a particular interest on their main features that have made them efficient for VANETs, and their comparison with respect to some standards metrics. Future directions with respect to VANETs routing schemes are also discussed.
  • SFAMSS: A Secure Framework For Atm Machines Via Secret Sharing
    Zeinab Ghafari,Taha Arian and Morteza Analoui, Iran University of Science and Technology,Iran.
    As ATM applications deploy for a banking system, the need to secure communications will become critical. However, multicast protocols do not fit the point-to-point model of most network security protocols which were designed with unicast communications in mind. In recent years, we have seen the emergence and the growing of ATMs (Automatic Teller Machines) in banking systems. Many banks are extending their activity and increasing transactions by using ATMs. ATM will allow them to reach more customers in a cost effective way and to make their transactions fast and efficient. However, communicating in the network must satisfy integrity, privacy, confidentiality, authentication and non-repudiation. Many frameworks have been implemented to provide security in communication and transactions. In this paper, we analyze ATM communication protocol and propose a novel framework for ATM systems that allows entities communicate in a secure way without using a lot of storage. We describe the architecture and operation of SFAMSS in detail. Our framework is implemented with Java and the software architecture, and its components are studied in detailed.
  • QoS-based Performance Evaluation of Channel-Aware/QoS-Aware Scheduling Algorithms for Video-Applications over LTE/LTE-A
    Najem Sirhan, Gregory Heileman, Christopher Lamb and Ricardo Piro-Rael,University of New Mexico,United States.
    Long Term Evolution (LTE) is de ned by the Third Generation Partnership Project (3GPP) standards as Release 8/9. The LTE sup- ports at max 20 MHz channel bandwidth for a carrier. The number of LTE users and their applications are increasing, which increases the demand on the system BW. A new feature of the LTE-Advanced (LTE-A) which is de ned in the 3GPP standards as Release 10/11 is called Carrier Aggregation (CA), this feature allows the network to ag-gregate more carriers in-order to provide a higher bandwidth. Carrier Aggregation has three main cases: Intra-band contiguous, Intra-band non-contiguous, Inter-band contiguous. The main contribution of this paper was in implementing the Intra-band contiguous case by modify-ing the LTE-Sim-5, then evaluating the Quality of Service (QoS) per-formance of the Modi ed Largest Weighted Delay First (MLWDF), the Exponential Rule (Exp-Rule), and the Logarithmic Rule (Log-Rule) scheduling algorithms over LTE/LTE-A in the Down-Link di-rection. The QoS performance evaluation is based on the system's average throughput, Packet Loss Rate (PLR), average packet delay,and fairness among users. Simulation results show that the use of CA improved the system's average throughput, and almost doubled the system's maximum throughput. It reduced the PLR values almost by a half. It also reduced the average packet delay by 20-40% that varied according to the video bit-rate and the number of users. The fairness indicator was improved with the use of CA by a factor of 10-20%.
