    Ad hoc networks, which cover a variety of network paradigms for specific purposes, such as mobile ad hoc networks, sensor networks, vehicular networks, underwater networks, underground networks, personal area networks, and home networks, promise a broad range of applications in civilian, commercial, and military areas. The aim of the annual International Conference on Ad Hoc Networks (AdHocNets) is to provide a forum that brings together researchers from academia as well as practitioners from industry to meet and exchange ideas and recent research work on all aspects of ad hoc networks.

    • MobileR: Multi-hop Energy Efficient Localised Mobile Georouting in Wireless Sensor and Actuator Networks

Different routing protocols have been proposed to improve routing in terms of energy efficiency through the use of controlled mobility enabled sensors . We introduce MobileR. Unlike literature proposals also using actuators, MobileR considers the cost of a full path toward one of its neighbours instead of the cost of the direct edge toward it. To do so, MobileR computes in advance the possible routing paths over the next hops relying on the one-hop neighbours and their possible relocations. Moreover MobileR is fully localised and stateless. We evaluate our solution in terms of cumulative energy consumption with regard to network density. Experiments show that, with sufficient node degree, energy used for routing is significantly reduced and so network lifetime is extended.

    • Improving Data Dissemination in Multi-hop Cognitive Radio Ad-Hoc Networks

SURF classifies the available channels on the basis of primary radio unoccupancy and the number of cognitive radio neighbors using the channels. Through extensive NS-2 simulations, we compare the performance of SURF with three related approaches. Simulation results confirm that SURF is effective in selecting the best channels for efficient communication and for highest dissemination reachability in multi-hop CRNs.

    • Collaborative Spectrum Sensing Scheme: Quantized Weighting with Censoring

These techniques depend on the actual knowledge of the radio environment being inspected, i.e. signal characteristics, noise levels etc. The simplest and most common spectrum sensing technique is energy based detection that needs no a priori knowledge about the monitored spectrum, but may lead to imprecision when assessing the possible presence (or absence) of a primary user. Therefore, possible collaboration among the nodes performing the energy based spectrum sensing (in terms of sensing reports exchanges) improves the reliability and avoids the hidden terminal problem caused by the shadowing from large obstacles. This paper introduces a novel collaborative spectrum sensing scheme with light communication overhead called Quantized Weighting with Censoring (QWC). The scheme includes censoring of the unreliable sensing reports in some range of uncertainty and introduces weighting coefficients for different quantization levels. The performances of the QWC scheme are compared with the Majority Voting (MV) and Equal Gain Combining (EGC) schemes. The results show that the QWC scheme outperforms the well known EGC scheme.

    • Performance Analysis of Multichannel Radio Link Control in MIMO Systems

In this paper, we introduce a MIMO system model, propose a multichannel radio link control protocol and a dynamic channel scheduling policy. We then conduct a performance study on the multichannel link control protocol with two different scheduling policies (, dynamic and static scheduling) using simulations. Simulation results show that the dynamic scheduling outperforms the static scheduling. It is observed that the average packet delay with the dynamic scheduling increases with the average error rate of parallel channels, but decreases with the variance in the error rates of parallel channels. More interestingly, the number of parallel channels has only an insignificant impact on the average packet delay, when the dynamic scheduling is applied in MIMO systems, from which we confirm that the use of parallel channels is a favorable option for packet data networking in the point of view of the link-layer performance.

In this paper, …In video surveillance with resource-constrained devices such as wireless video sensor nodes, power conservation, intrusion detection, and security are important features to guarantee. In this paper, we intend to preserve the network lifetime while fulfilling the surveillance application needs. We take into account security by considering that a malicious attacker can try to predict the behavior of the network prior to intrusion. These considerations lead to the definition of a novel chaos-based scheduling scheme for video surveillance. We explain why the chaos-based approach can defeat malicious intruders. Then, by simulations, we also compare our chaos-based scheduling to a classical random scheduling. Results show that in addition of being able to increase the whole network lifetime and to present comparable results against random attacks (low stealth time), our scheme is also able to withstand malicious attacks due to its fully unpredictable behavior.
