  • Modelling and analysis data fragmentation in IEEE 802.15.4 slotted CSMA/CA
           protocol without ACK mode
    • Authors: Mouloud Atmani, Djamil Aïssani, Yassine Hadjadj-Aoul
      Pages: 4 - 21
      Abstract: The low-rate wireless personal area networks (WPANs), as wireless sensor networks (WSNs), suffer from many constraints. The IEEE 802.15.4 standard proposes the slotted CSMA/CA as a communication channel access mechanism with collision avoidance that take into account the constraints of WPANs. In this paper, we propose to introduce a data fragmentation mechanism into slotted CSMA/CA to improve a bandwidth utilisation. The novelty, in this paper, is the use of the fragmentation mechanism to replace an acknowledgement frame after the transmission of the fragment and the remaining frame. The beacon frame is used to confirme the success transmission of a data fragment. To evaluate the performances of our proposition, we have developped a three dimension Markov chain which modelises the behaviour of the node using IEEE 802.15.4 with data fragmentation mechanism without using an ACK frame. The analytical results of the network throughput and the transmission success delay demonstrate the improvement of the bandwidth occupation.

  • Analysing reward measures of LARES performability models by discontinuous
           Markov chains
    • Authors: Alexander Gouberman, Martin Riedl, Markus Siegle
      Pages: 22 - 42
      Abstract: This paper presents a new method for specifying and analysing Markovian performability models. An extension of the LARES modelling language is considered which offers both delayed and immediate transitions, as well as rate and impulse rewards on whose basis different types of reward measures can be defined. The paper describes the evaluation path, starting from the modular and hierarchical LARES description and leading via a flat labelled transition system to the underlying stochastic model. The latter is a continuous-time Markov chain with fast transitions which, by taking the limit of the fast transition rates, can be interpreted as a CTMC with stochastic discontinuities. Finally, by continuisation of impulse rewards and an aggregation process, a standard Markov reward model is obtained.

  • On the dependability evaluation of a virtual multiple input multiple
           output link
    • Authors: Mohamed Escheikh, Kamel Barkaoui
      Pages: 43 - 58
      Abstract: Cooperative diversity or virtual antenna arrays (VAA) enables transmission range extension and provides robustness enhancements in wireless multi-hop relay networks, when compared with relaying non-cooperative diversity-based schemes. Moreover redundant spare nodes willing to cooperate when used in a virtual multiple input multiple output (VMIMO) scheme allow better dependability and lead to a more efficient transmission that is of particular interest in mobile environment. This talk addresses a model-based probabilistic approach for dependability assessment of a VMIMO link. More precisely, we show how through Markov models, we can evaluate availability and survivability measures of a VMIMO link. We show through extensive numerical computations how instantaneous availability (A(t)) decreases for different failure rates and how the steady state availability (As) behaves with respect to the number of redundant spare nodes. Also we illustrate how node failure rates affect VMIMO link survivability metrics, i.e., excess loss due to failure (ELF) and excess delay due to failure (EDF). Finally we highlight reliability metrics related to VMIMO link [i.e., reliability (R(t)), mean time to failure (MTTF) and mean time to repair (MTTR)] and we show how they behave with respect to node failure and repair rates.

  • Modelling and performance analysis of video and voice streams in the IEEE
           802.11e-EDCA WLANs with TXOP bursting under fading channel
    • Authors: Mohand Yazid, Louiza Bouallouche-Medjkoune, Djamil Aïssani
      Pages: 59 - 77
      Abstract: Performance evaluation of the IEEE 802.11e network has been the subject of several research papers. Especially, the transmission opportunity limit (TXOPLimit) has been proven efficient for achieving differentiated quality of service (QoS) and improving the wireless bandwidth utilisation. However, most existing analytical models have been developed under unrealistic assumption that the wireless channel is error-free. Hence, the efficiency and the performance level of the TXOPLimit in an error-prone channel are questionable. In this paper, we aim at proposing a new Markov chain model of the IEEE 802.11e network including the TXOPLimit and the packet error rate (PER). Then, we derive the saturation throughput of the IEEE 802.11e network in cases of aggregated and non-aggregated packets. The obtained results show that, the TXOPLimit efficiency is highly degraded under the effect of bit error rate (BER) and packet length.

      Abstract: An atomic broadcast problem constitutes an essential component in fault-tolerant distributed systems. an atomic broadcast algorithm ensures that all processes deliver the same messages sequence. Many algorithms solving the atomic broadcast problem have been published. Recently, a new Paxos-based atomic broadcast algorithm has been proposed for clustered systems, named Ring Paxos. It inherits many of Paxos characteristics: safe under asynchronous assumptions, live under weak synchronous assumptions, and requires a majority of non-faulty processes to ensure progress. However, the proposed algorithm relies on strong assumptions, and uses the group membership for faults tolerance. Recently, a new failure detector Ring Paxos-based atomic broadcast algorithm (FD-RP) for asynchronous distributed systems have been proposed. It inherits some of Ring Paxos characteristics and uses failure detectors to tolerate failures instead of a membership service. The aim of this paper is to complete the work done in our previous work by evaluating the performance of the FD-RP protocol by simulation and compare it with the Ring Paxos protocol, results show that the proposed protocol performs better than the Ring Paxos protocol in some situation and is recommended in applications with low latencies.

  • Formal approach based on petri nets using agent paradigm for
           m-maintenance

      Abstract: The long use of a system in a manufacturing environment causes its degradation, thus the maintenance activity is required in this environment to keep and to improve the efficiency of the system. The new development in networking technologies enhances maintenance strategies and gives birth to remote maintenance (tele-maintenance, e-maintenance, m-maintenance). This maintenance makes information available anywhere/anytime and provides maintenance-personnel with the necessary information at the suitable time. This new type of maintenance reduces the maintenance costs and solves the problem of the unavailability of experts. Mobile agent as a rich design concept brings many facilities in the development of m-maintenance, however few works are elaborated in this stage. The objective of this work is both: 1) the proposition of a based mobile multi-agent architecture dedicated for m-maintenance in manufacturing systems; 2) the exploitation of high level petri nets in the specification, simulation and verification phases of the architecture development.
