The Wireless On-Demand Networks and Services Conference (WONS) is happily toasting its 12th edition, and it does so in beautiful Cortina d'Ampezzo, \Queen of the Dolomites" (a UNESCO World Heritage Site) and venue of the 1956 winter Olympics. This year's edition of WONS is held on January 20{22, 2016, and it is co-located with the Seventh Nordic Workshop on System and Network Optimization for...

Mobile devices have been augmented by Multi-path TCP (MPTCP), enabling them to exploit the path diversity. Signal aware MPTCP (SA-MPTCP) takes the signal quality, playing a significant role in energy waste, into account to enhance MPTCP energy consumption. The problem is formulated as a decision making problem under uncertainty, endeavoring to optimize energy efficiency by selecting the best policy...
Bluetooth (BT) devices are usually grouped in a star topology in small clusters called personal area networks (PANs). The population of BT PANs is limited to 8 devices, but setups in entertainment theme parks or interactive installations might want to employ a larger number of mobile devices. In those scenarios, only off-theshelf devices, without any hardware modifications, can be accepted, so a PAN...
This paper describes the evaluation of a multihop wireless networking solution for Smart Grid metering in an industrial environment. The solution relies on RPL, 6LoWPAN, and IEEE 802.15.4g protocols, and has been implemented using low-power and low-capacity devices. Also, it supports both TCP and UDP protocols to transport traffic from DLMS/COSEM Smart Grid metering applications. The experimental...
This paper studies the coverage aspects of a low altitude platform (LAP) system that can form a temporary communication network. The system consists of multiple autonomous drones equipped with dual-band Wi-Fi access points (APs) with ad hoc capabilities to form a mesh network. The suitability of the LAP system is evaluated from the coverage point of view with calculations and simulations. The results...
Full-duplex radio allows signals to be transmitted and received simultaneously by utilizing Self-Interference Cancellation (SIC). At a maximum, it can double the throughput of traditional half-duplex systems. To enhance throughput as much as possible, it is important to utilize downlink and uplink transmissions simultaneously. This paper proposes Hidden Chain MAC protocol, which improves throughput...
Snow avalanches are an ever-present reality in alpine regions – They can cause heavy damage to settlements and infrastructure. Thus, understanding the behavior and the dynamics of avalanches is an important challenge. Current modeling and simulation techniques of avalanche dynamics do not yet consider a precise description of the inner dynamics. In this paper, we present AvaRange, a measurement based...
Sharing Transmission Opportunity period (TXOP) technique is recently defined by IEEE 802.11ac to allow simultaneous downlink transmissions. In this paper, we focus on the basis of this technique and the behavior of the access point (AP) to manage the multi-user access. We discuss the different steps required to allow simultaneous downlink transmissions. Based on simulation results, we prove that TXOP...
The control of a platoon using IEEE 802.11p is an active research challenge in the field of vehicular networking and cooperative automated vehicles. IEEE 802.11p is a promising technology for direct vehicle to vehicle communication, but there are concerns about its usage for the control of platoons as it suffers packet losses due to congestion in highly dense scenarios. On the other hand, Visible...
Offloading through WiFi access networks has been recently proposed as a cost-effective solution for coming up against the unprecedented increase in the mobile data traffic volume. However, apart from reducing the operational costs of a network operator, WiFi access can be also promoted as an alternative low-cost service for users with low willingness-topay. In this paper, we consider a monopolistic...
A framework is proposed for future energy aware dynamic spectrum access broadband networks where the demand for the radio spectrum is time varying. The network comprises of several Wireless Service Providers (WSPs) whose aim is to maximize profit by providing broadband services to users in a specific location, a central regional entity named Transmission Central Authority (TCA) and the end users seeking...
In perspective, the effectiveness and attractiveness of multimedia communications rely both on such disruptive services as Web Real-Time Communication (WebRTC), and on such reliable mobile infrastructures as Long Term Evolution (LTE). WebRTC is the innovative protocol letting HTML5 compliant browsers to communicate in real-time using a peer-to-peer architecture. LTE on the other hand, is the current...
Nowadays, IEEE 802.11 networks are the most popular option to have wireless access to the Internet and a promising technology to tackle the digital divide that accounts for 2/3 of the world population. However, the popularity of these networks have raised a complex discovery and connection process, i.e., any device has to pass through an expensive scanning process of available Access Points in crowded...
