We present our recent work investigating how mobility prediction can be exploited for improving the performance of mobile users in two directions: proactive caching requested content close to the network attachment points where a mobile has a high probability to connect to and DASH (Dynamic Adaptive Streaming over HTTP) video quality adaptation. For proactive caching we discuss a new model to proactively cache content based on both mobility prediction and content popularity. An important feature of the model is that it dynamically adapts caching decisions to the relative importance of the two factors. For DASH adaptation we discuss a procedure that exploits mobility and throughput prediction to select the quality levels of video segments requested by a DASH player in order to achieve improved QoE, in terms of both high video quality and few video quality switches.

A large enough separation in the frequency domain between signals going in opposite directions is instrumental to facilitate the implementation of transceivers able to isolate the receiver from the high power transmitted signal. A more flexible allocation of spectrum requires the application of interference cancellation countermeasures. In this paper we address the digital processing involved in the realization of echo cancelling filters in the analog domain, designed to avoid the saturation of the receiver front-end due to the coupling of the transmitted signal and its out-of-band content. The design goal will be the reduction of the sampling rates, so large bandwidth interference waveforms can be attenuated working at sub-Nyquist rates.

Air pollution monitoring has become an essential requirement for cities worldwide. Currently, the most extended way to monitor air pollution is via fixed monitoring stations, which are expensive and hard to install. To solve this problem, we have developed EcoSensor, a solution to monitor air pollution through mobile sensors. It is deployed with off-the-shelf hardware such as Waspmote (based on the Arduino platform), low-end sensors, and Raspberry Pi devices.

The impact of frame aggregation on wireless network performance increases dramatically with higher data rates. The key problem is that the transmission time of packets decreases while the medium access, preamble and packet header overhead remain the same. Recent 802.11 standards address this issue using frame aggregation, i.e., grouping multiple data frames in a single transmission to reduce the overhead. This already provides substantial efficiency gains in networks operating in the 2.4 GHz and 5 GHz bands, and for future 60 GHz networks such as 802.11ad, gains are even more pronounced due to the order-of-magnitude higher data rates. In 802.11ad, frame aggregation becomes crucial to achieve the multi-gbps data rates that are possible in theory, since medium access overhead can be 20x larger than the time required to transmit a single packet. While frame aggregation is essential, it very much depends on the traffic patterns present in the wireless network, and a node may not always have enough packets in the transmit queue to achieve a sufficiently large aggregated frame size. In this paper, we investigate in which case nodes should wait to construct a larger aggregated packet before starting the channel access procedure. We present a simple waiting policy for the uplink case that either waits for a minimum number of packets or for a maximum amount of time, whichever comes first. For the downlink case, we utilize a maximum weight scheduling policy with a maximum waiting time. Our results show that both policies significantly improve medium utilization, thus increasing throughput and reducing end-to-end delay.

In emergency scenarios such as earthquakes, fires, avalanches, or building collapses, it is necessary to discover people trapped under debris or anyway hidden from eyesight. In this paper, we propose RescuePal, an energy-efficient smartphone-based system that does not require any interaction by the victim and does not use energy-expensive GPS. RescuePal leverages a wake-up system based on sounds that activates the WiFi interface of the victim's smartphone only when the rescuer is close, to save energy. After presenting the system, we mathematically formulate an optimization problem so as to find the sound frequency and power level that minimizes WiFi false activations and yet guarantees high discovery efficiency. RescuePal has been implemented on off-the-shelf Android-based devices, and its performance has been evaluated on a realistic use-case scenario of victims inside a building. Finally, the energy consumption of RescuePal has been calculated using the Power Monitor hardware tool. Results demonstrate that RescuePal is highly effective and saves more than 60% of energy with respect to an approach based only on WiFi.

We have previously presented Intent, a medium access control scheme for WLANs based on cooperative, distributed, non-binding frame scheduling. The main idea behind Intent is “intention sharing”-a mechanism that allows a node to be aware of transmissions previously scheduled by its neighbors. We now extend this scheme to networks with hidden nodes. We give a formulation of the scheduling problem and solve for the optimal solution using mixed-integer programming in a range of scenarios covering both mesh and infrastructure networks of varying density. We also provide an algorithmic solution and perform simulations using four variants of this, comparing the results with both the optimal solution and standard 802.11. Our algorithmic solution gives significantly better performance than 802.11 and comes within 1.1 times optimal performance when full, two-hop scheduling information is available. In addition, we show that it is not necessary to exchange complete scheduling information in order to perform distributed scheduling effectively but rather a conflict resolution or avoidance mechanism combined with non-binding schedules allows for similar performance with only a single round of information exchange between neighbouring nodes.

The need to improve road traffic management is evident worldwide. Growing congestions on the roads along with a gradual increase of pollution and concern for improving traffic safety have prompted to explore the potential of the Intelligent Transportation Systems through numerous research projects funded by public entities and/or the automotive industry. However, due to various reasons, including the global economic crisis, such a goal has not been reached till now. Thus, the efforts now should be directed toward the development of low-cost solutions that help to fulfill the main objectives of Vehicular Ad-hoc Networks to support safety and non-safety vehicular applications. This paper proposes the deployment of a Vehicular Ad-hoc Network based only on mobile devices for the communication between vehicles. This proposed scheme uses a hybrid architecture network that combines an online mode with an offline mode, depending on the existence of Internet access. The proposal described here has been developed for the Android platform and the obtained results are promising.

Mobile broadband (MBB) networks underpin numerous vital operations of the society and are arguably becoming the most important piece of the communications infrastructure. In this demo paper, our goal is to showcase the potential of a novel multi-homed MBB platform for measuring, monitoring and assessing the performance of MBB services in an objective manner. Our platform, MONROE, is composed of hundreds of nodes scattered over four European countries and a backend system that collects the measurement results. Through a user-friendly web client, the experimenters can schedule and deploy their experiments. The platform further embeds traffic analysis tools for real-time traffic flow analysis and a powerful visualization tool.

The ability to predict the behavior of cars that are parked in an urban area can be very useful to the development of vehicular networks that leverage these parked cars. In this paper, we analyze the mobility patterns of people living in US cities who use cars as their primary means of transportation. We process and analyze survey data from the metropolitan areas of Atlanta, Chicago, and Knoxville, to extract statistics on the parking behaviors of individual cars.

Future Access and Backhaul Networks need to significantly carry more data traffic, which calls for network densification. However, when many small cells are densely deployed, the backhaul network might become the bottleneck, as it is economically infeasible to wire every small cell or power them on constantly. Therefore, an effective configuration of a Small Cell Wireless Backhaul Network is important due to its multi-hop operation, possibly operating in mmWave bands. In this paper, we propose to use Software-Defined Networking for the Operation and Management of Small Cell Wireless Backhaul Networks. A SDN controller based in OpenDaylight is in charge of adaptively powering on/off Small Cells and reconfiguring the backhaul forwarding topology, according to traffic demands. The SDN controller uses an optimizer module which can be configured with different policies in order to minimize the energy cost or optimize capacity or latency. We extend OpenFlow in order to gather wireless and power consumption statistics, which are exchanged between Controller and Small Cell Backhaul nodes using a LTE Out-Of-Band Control Channel.
