Outlier detection is a well studied problem in various fields. The unique challenges of wireless sensor networks such as limited bandwidth, memory, energy, and unreliable communi- cation make this problem especially difficult. Sensors can detect ...

This research further investigates the recently introduced (in [4]) paradigm of radiation awareness in ambient environments with abundant heterogeneous wireless networking from a distributed computing perspective. We call radiation at a point of a ...

Wireless sensor networks are characterized by a large number of non-standardized protocols and varying application requirements. This creates need for a systematic approach to rapidly design and optimize deployment specific protocol stacks. We employ ...

WLAN has proven itself as the most economical wireless access technology over the time. Its widespread deployment encouraged 3GPP (3rd Generation Partnership Project) to standardize the integration of such non-3GPP access technologies into the existing ...

We present two measurement campaigns reflecting the end-user QoS of a large municipal WiFi (IEEE 802.11 WLAN) network on the end-user QoS of three commercial 3.5G (HSPA) mobile data networks and on the spectrum occupancy of the 2.4 GHz ISM band. Our ...

This paper introduces two protocols for communication in infrastructure networks consisting of a central server, stationary basestations and mobile devices. Mobile devices use IEEE 802.15.4 to communicate with the basestations. Among other things, the ...

This paper considers the use of wireless mesh networks as a communication infrastructure for monitoring and controlling industrial plants and processes such as solar power plants. In the latter, several thousands, tiltable and rotatable flat mirrors (...

Indoor geopointing is a mobile computing field of application where high resolution compass data is required, in order to reliably identify digital objects on a map or within a scene. When mobile application developers wish to implement geopointing ...

In Wireless Sensor Networks (WSNs) there are network functions and applications that need to know the localization of a node such as the association of the sensed data with a given position. In general, it may be impossible or unfeasible to have either ...

Host Identity Protocol (HIP) emerges as the most suitable identification protocol for the Internet of Things. HIP not only provides identifier/locator split but also a key agreement procedure named HIP Base Exchange, which bootstraps security ...

In this article, we propose a novel extension for the OLSR routing protocol, "Multi-Level OLSR" (ML-OLSR): it introduces a hierarchy between links, where some links are preferred to others. The objective is that the network consisting of links of most ...

Recently, the IEEE 1609.4 protocol has been defined to enable multi-channel operations in a vehicular environment, and to guarantee interference-free co-existence of safety-related and non-safety related applications in the same network. To meet these ...

Results from recent studies have pointed out that two well-known spatial and temporal mobility metrics for mobile ad hoc networks have critical drawbacks. At the same time, two new spatial and one temporal mobility metrics have been proposed and ...

WiMAX, as known as IEEE standard 802.16, is a wide range broadband wireless access network which has a significant good support for the quality of service. According to IEEE standard 802.16e WiMAX has support also for mobility. One of the key advantages ...

Gateway discovery in vehicular networks is very important in order to permit the connection to the Internet or to heterogenous networks. Fault tolerance, load balancing, and QoS are very important aspects to enhance the performance of the network and ...

In this paper, we present an SMS-based Android botnet. Since all mobile phones have SMS services as a feature, we will use SMS as the medium of propagation of Command and Control messages between the botnet controller and the victim devices. The ...

We propose a critical improvement of the LEACH (Low-Energy Adaptive Clustering Hierarchy) routing protocol for the optimization of the energy consumption as well as memory occupation of Wireless Sensor Network (WSN). Our protocol LEACH-M uses a cascade ...

In a pervasive computing environment, principle authentication verifies if a person is the one he claims to be. However, being sure that you are talking to the expected entity does not mean this entity is trusted to do what you expect him to do, and ...

IPv6 over Low power Wireless Personal Area Networks (6Lo-WPAN) is a protocol architecture that has recently been ratified to enable the seamless interconnection of wireless sensor networks (WSN) to the Internet. This opens up a wealth of application ...

ETX (Expected Transmission Count) is shown to be the best link metric in terms of higher throughput for wireless multi-hop network with stationary-nodes having single radio. Some recent work, however, shows that ETX may exhibit high sensitivity to ...

Most typically, trend of future cellular network is to give access to a large number of applications such as: VoIP, videoconferencing, interactive gaming, multimedia services, etc. The integration of heterogeneous wireless networks is designed to ...

Long Term Evolution (LTE) is seen as the key enabler for delivering the fourth generation of mobile broadband and is the first cellular network primarily designed based on IP. Thus, telecom operators must support the diverse IP-based mobile applications ...

Many WSN algorithms and applications are based on knowledge regarding the position of nodes inside the network area. However, the solution of using GPS based modules in order to perform localization in WSNs is a rather expensive solution and in the case ...

In this work we describe the demo of UPMT - Universal Per-application Mobility management using Tunnels. UPMT is a per-application mobility management solution highly suitable for "ABC" (Always Best Connected) mobility scenarios since it provides ...
