Large scale wireless sensor networks present interesting challenges in many applications due to a number of factors, such as, energy constraints, the dynamic nature of the network topology and various application needs. An important issue is how the ...

Rapid evolution of wireless networking has provided wide-scale of different wireless access technologies like Bluetooth, ZigBee, 802.11a/b/g, DSRC, 3G UMTS, LTE, WiMAX, etc. The complementary characteristic of the above architectures motivates next ...

The performance of an individual TCP flow with a vertical handoff has been studied in several papers. However, the effect of a vertical handoff on multiple TCP flows has been little studied. In this paper we study the behaviour of multiple competing TCP ...

Ubiquitous access to information anywhere, anytime and anyhow is a main feature of the upcoming 4G mobile communication networks, which will interconnect existing and future networks via common IP core. 4G networks are termed, therefore, as All-IP and ...

Understanding how humans move is a key factor for the design and evaluation of networking protocols and mobility management solutions in mobile networks. This is particularly true for mobile scenarios in which conventional single-hop access to the ...

The International Civil Aviation Organization (ICAO) has recently standardized the IP-based aeronautical telecommunication network (ATN/IP) as a next generation communication network for the aviation industry. ATN/IP considers Mobile IPv6 (MIPv6) as a ...

We consider sensor networks where the sensor nodes are attached on entities that move in a highly dynamic, heterogeneous manner. To capture this mobility diversity we introduce a new network parameter, the direction-aware mobility level, which measures ...

WiMAX/802.16 mesh network has become an attractive infrastructure by its ability to provide high capacity broadband access to the backhaul network over seamless distances, with minimum cost deployment. This past year, a noticeable improvement of this ...

In wireless multihop networks such as MANETs or Wireless Mesh Networks (WMN), an Internet gateway (IGW) is a node that provides Internet connectivity, linking the wireless network with the global Internet. Congestion around the IGW represents a ...

Video streaming over Wireless Mesh Networks (WMNs) can take advantage of the presence of multiple paths between each source and destination pair, as well as of the availability of multiple radio interfaces on the mesh nodes. In this paper, we propose a ...

Vehicular Ad Hoc Networks (VANETs) are a new trend that offers many opportunities to the development of a wide range of interesting services. These services range from providing entertaining applications, such as videoconferencing, to enhancing safety ...

This paper introduces Blackbone2, a novel fully decentralized algorithm that aims at creating a robust backbone in ad hoc networks. Backbone robustness is supported by a 2-Connected m-dominating Set, 2,m-CDS, and decentralization relies on the usage of ...

In this paper, we develop a single user and a multi user version of a Distributed Underlay Channel Assignment (DUCHA) algorithm for spectrum access to a downlink channel of a primary cell for a cognitive cooperative ad hoc network overlaid with the ...

Handoff delay is one of the major problems in Wireless Mesh Network (WMN) that needs to be solved in order to allow time-critical and real-time applications run continuously during handoff. We have developed a fast handoff scheme called MeshScan to ...

Recommender systems using collaborative filtering are a well-established technique to overcome information overload in today's digital society. Currently, predominant collaborative filtering systems mostly depend on huge centralized databases to store ...

Cognitive Radio (CR) coexistence with the primary user has emerged as one of the main tasks for the success of the spectrum multi-users auction proposals. Known architectures that arrange the spectrums sharing for different users are coordinated, ...

In trying to emulate the spatial position of wireless nodes for purpose of analysis, we rely on stochastic simulation. And, it is customary, for mobile systems, to consider a base-station radiation coverage by an ideal cell shape. For cellular analysis, ...

The International Civil Aviation Organization (ICAO) is currently standardizing an IPv6-based Aeronautical Telecommunications Network (ATN/IP) as a next generation communication network for air traffic management. Thereby, ATN/IP considers Mobile IPv6 (...

In large hospitals, location discovery and contact discovery presents possibilities to quickly find someone in an emergency, to narrow the epidemiologic scope of an outbreak, and to reinforce good safety practices. An RFID architecture can make the ...

In this paper we propose a cross-layer design of a Wireless Sensor Network (WSN) to increase communications efficiency. A simple and low cost wireless physical layer using multiple carrier frequencies is proposed, utilising pulse shaping to increase the ...

Wireless sensor networks are characterized by stringent battery resource. Owing to a wide range of applications, sensor networks are expected to support variable amounts of traffic loads. The resulting peak loads may drive the network into congestion, ...

This paper presents a novel store-and-forward packet routing algorithm for Wireless Body Area Networks (WBAN) with frequent postural partitioning. A prototype WBAN has been constructed for experimentally characterizing on-body topology disconnections in ...
