This paper studies a cloud-assisted procedure to improve the user's Quality of Experience (QoE) in HTTP Adaptive Streaming (HAS) services. HAS delivers video streaming services following a client-server architecture and requires the client to originate ...

Internet interconnection is the glue that holds the Internet together via bilateral network interconnection agreements of best effort (i.e. non-assured) quality. This study provides qualitative analysis and assessment of the multidimensional impacts of ...

In this paper, we propose an algorithm to efficiently (re)-deploy the wireless mobile routers of a substitution network by considering the energy consumption, a fast deployment scheme and a mix of the network metric. We consider a scenario where we have ...

In this paper, a new mechanism for topology control in wireless mesh networks is proposed. We evaluate the application to this problem of the centrality metrics developed by social network analysts. Our target network is a wireless mesh network created ...

The concept of autonomous mobile agents gets a lot of attention in the domain of wireless sensor networks (WSN) or wireless sensor and actuator networks (WSAN). Multiple robots that coordinate or cooperate with other sensors, robots or human operator, ...

This work discusses the total transmission delay distribution in wireless networks where medium access follows the IEEE802.11 DCF medium access protocol. It does not propose a new model to derive the delay distribution of such protocol but focuses on ...

Vehicular ad hoc networks (VANETs) are emerging as a novel paradigm for safety services, supporting real-time applications (e.g., video-streaming, Internet browsing, online gaming, etc.). However, maintaining ubiquitous connectivity remains a challenge ...

Multi-radio IEEE 802.11 nodes make use of the multiple channels defined by the standard in order to improve multi-hop networks performance. Since the number of available non-overlapping channels is usually higher than the number of interfaces per node, ...

Energy efficiency is a key issue for ad-hoc networks and several proposals have been explored in order to maximize network lifetime. This work analyzes the most relevant modifications proposed in the literature for OLSR in order to make it energy ...

Recent studies have shown that the IEEE 802.15.4 MAC protocol may suffer from severe limitations, in terms of reliability and energy efficiency, if CSMA/CA parameter settings are not appropriate. On the other hand, choosing the optimal setting that ...

Various studies have shown that a substantial portion of the data gathered in real-world sensing applications is faulty. Most existing fault-detection approaches are off-line, centralised, and rely heavily on expert domain knowledge which may not always ...

The IEEE 802.15.4 standard is widely used in wireless sensor network applications. While previous work had attempted to model such protocol based on Petri nets, they focused on CSMA/CA, leaving aside the beacon mode implications. Our main contribution ...

Energy depletion of sensor nodes is one of the major issues in the wireless sensor networks. Data gathering reveals a convenient solution in order to conserve the sensor nodes energy. It aims at using mobile robots able to visit sensor nodes in order to ...

In certain surveillance applications it is imperative that the deployed Wireless Sensor Network (WSN) is not detected by the adversaries before the intruding party is detected by the WSN (i.e., the WSN is in the stealth mode of operation). Limiting the ...

The tremendous increase of the traffic demand in cellular networks imposes a massive densification of the traditional cellular infrastructure. The network architecture becomes heterogenous, in particular 4G networks where LTE micro eNodeBs are deployed ...

Vehicular ad hoc networks have emerged as a promising field in wireless networking research. Unlike traditional wireless sensor networks, vehicular networks demand more consideration due to their assorted road topology, the high mobility of vehicles and ...

This paper proposes a novel mechanism to provide with security to existing Data-Centric Storage (DCS) solutions for Wireless Sensor Networks. The goal is to achieve a high security level without modifying standard DCS premises or increasing the network ...

In this paper we present a new routing approach, Context-Aware Community Based Routing(CACBR) that exploits the social-based movement pattern and the context-awareness of nodes, for efficient message delivery in Delay Tolerant Network. The nodes having ...

Wireless Sensor Networks (WSN) are composed of constrained devices and deployed in unattended and hostile environments. Most papers presenting solutions for WSN evaluate their work over random topologies to highlight some of their "good" performances. ...

In this paper, we describe a lifetime improvement method using mobile sink node for Internet of Things (IoT) device and discuss the major technologies involved in IoT. Additionally, we discuss the potential scope of IoT and the major technologies ...

Ensuring the aspired outcome quality of network-based applications has ever implied an appropriate prognosis of the performance behavior the underlying communication structures will exhibit prior to potential optimization steps. However, the reliable ...
