In vehicular networks, the packet losses in the path between source and destination occur due to packet collisions, fast movement and a limited communication range of vehicles. Reliability mechanisms at different layers are used to mitigate the impact ...

Considerable attention has been assigned to Vehicular Cloud towards identifying methods to utilize under-used, available computing and physical resources of vehicles effectively. Most work on vehicular cloud is so far on the taxonomy definition level, ...

Vehicular Networks (VANETs) are an emerging network that enables the communication among the vehicles, in order to promote a safe and efficient traffic, avoiding crashes and preventing hazards. These vehicles transit on the streets and highways, and ...

Message dissemination and data collection from vehicles are two key enablers of Intelligent Transportation System services that can be offered by a Vehicular Ad-Hoc Network (VANET) technology. In this work we propose a fully distributed protocol for ...

This paper presents a performance evaluation of the scalable video streaming over mobile ad hoc networks. In particular, we focus on the rate-adaptive method for streaming scalable video (H.264/SVC). For effective adaptation a new cross-layer routing ...

This paper proposes different local\hyph search heuristics to improve the performance of geographical routing protocols in VANET networks, which typically relies the selection of the next node only on the best candidate. The presented algorithms are ...

Vehicular Ad Hoc Networks (VANETs) are wireless networks that emerged thanks to advances in wireless technologies and in the automotive industry. Orthogonal Division Multiplexing (OFDM) has been adopted as a candidate for IEEE 802.11p standard due to ...

In this paper, from a measurement study and analysis of SMS based on traces coming from a nationwide cellular telecommunication operator during a two month period, we propose a DTN (Delay Tolerant Network) like network protocol for delivering SMS. More ...

Networks of constrained devices play an important role in the Internet of Things (IoT). In such networks congestion may lead to significant performance decrease and is a recurring phenomenon given the restricted hardware capacities of constrained ...

In disaster scenarios, communication systems usually consist of heterogeneous nodes and partially damaged infrastructure. Communication is important for rescue teams and victims as well but a serious problem because normal network systems like wired or ...

The Internet of Things (IoT) intends to interconnect massive amount of heterogeneous, smart devices, with the goal of interweaving the virtual world with the physical world. Smart Cities are typical IoT application domains, comprising networks with ...

In this paper we revisit the definition of user impatience in ubiquitous networks, by proposing a new characterization that does not reduce impatience to a simple timeout, like most previous works do. Instead, we characterize impatience by decoupling ...

Black-hole is a well-known routing attack through which malicious nodes try to downgrade the communication performance of wireless networks. On the other hand, opportunistic routing protocols aim to increase the reliability of communications compared to ...

Aggregation functions are intended to save energy and capacity in Wireless Sensor Networks (WSNs), by avoiding unnecessary transmissions. Aggregation functions take benefits from spatial and/or temporal correlations to forecast or to compress the real ...

In this research, we propose a high-speed simulator for rapidly determining protocol performance of a sensor network comprised of many terminals. We have developed this simulator by using General-Purpose Computing on Graphics Processing Units (GPGPU) ...
