Energy consumption and its management have been clearly identified as a challenge in computing and communication system design, where energy economy is obviously of paramount importance for battery powered devices. This thesis addresses the energy efficiency of mobile communication at the user end in the context of cellular networks.We argue that energy efficiency starts by energy awareness and propose EnergyBox, a parametrised tool that enables accurate and repeatable energy quantification at the user end using real data traffic traces as input. EnergyBox offers an abstraction of the underlying states for operation of the wireless interfaces and allows to estimate the energy consumption for different operator settings and device characteristics. The tool is used throughout the thesis to quantify and reveal inefficient data communication patterns of widely used mobile applications.We consider two different perspectives in the search of energy-efficient solutions. From the application perspective, we show that systematically quantifying the energy consumption of design choices (e.g., communication patterns, protocols, and data formats) contributes to a significantly smaller energy footprint. From the system perspective, we devise a cross-layer solution that schedules packet transmissions based on the knowledge of the network parameters that impact the energy consumption of the handset. These attempts show that application level decisions require a better understanding of possible energy apportionment policies at system level.Finally, we study the generic problem of determining the contribution of an entity (e.g., application) to the total energy consumption of a given system (e.g., mobile device). We compare the state-of-the-art policies in terms of fairness leveraging cooperative game theory and analyse their required information and computational complexity. We show that providing incentives to reduce the total energy consumption of the system (as part of fairness) is tightly coupled to the policy selection. Our study provides guidelines to select an appropriate policy depending on the characteristics of the system.

Mobilanvändarna fokuserar på interaktionen med applikationerna och förväntar sig att kunna kommunicera när det behövs utan att tänka på batteriets livslängd. Dessvärre resulterar ineffektiv användning av trådlösa gränssnitt (t.ex. WiFi eller mobilnät) i snabb batteriurladdning. Energiförbrukning och energihanteringär en av de stora utmaningarna för informationsteknologin just nu. Den här avhandlingen behandlar energieffektiviteten i mobilkommunikation med fokus på de mobila enheterna och användarens upplevelse. Den energiförbrukning som orsakas av kommunikationär inte proportionell mot mängden data som skickas vilket beror på hur data skickasöver t...

“…Perruci et. al [33] propose a cooperative mobile web browsing approach combining Bluetooth and cellular networks to decrease Web download time. In their architecture, two nodes (master-slave) are interested in the same data, and therefore the nodes download parts of the Web and share it afterwards.…”

Abstract-Energy consumption is becoming the Achilles' heel of the mobile user quality of experience partly due to undisciplined use of the cellular (3G) transmissions by applications. The operator infrastructure is typically configured for peak performance, whereas during periods of underutilisation the handsets pay the price by staying in high energy states even if each application only uses a fraction of the maximum available bandwidth.In this paper we promote a bi-radio scenario where instead of independently using own cellular connections, several users share a single cellular link offered by one member of a coalition (a rotating aggregator). We present Watts2Share, an architecture for energy-aware traffic consolidation whereby group members' data flows transmitted through a second radio (e.g., WiFi) are aggregated by the aggregator and retransmitted through the cellular link. Through careful and repeatable studies we demonstrate that this scheme saves up to 68% of the total transmission energy in handsets compared to a pure 3G scenario. The studies are based on a wide range of real traffic traces and real cellular operator settings, and further illustrate that this scheme reduces the overall energy by reducing the signalling overhead, as well as extending the lifetime of all handsets.

“…In [8] - [10], deployments of sparse infrastructures are studied as a means to enhance the performance of ad-hoc networks. Our scenarios are similar to the one presented in [11]: The authors propose cooperative web browsing where collocated devices download complementary parts of a web page from a base station and then exchange them via Bluetooth. Impact of mobility however has not been considered: cooperating nodes are assumed to be static.…”

“…Impact of mobility however has not been considered: cooperating nodes are assumed to be static. Works in [8] - [11] provide user-centric views by focusing on performances relevant to end users. The benefits/incentives for network operators to allow and support direct mobile-to-mobile communication are not sufficiently well understood.…”

Abstract-We consider a wireless content distribution service for mobile users that can be provided by mobile operators in their coverage areas. Our focus is on dense urban environments. A basic assumption is that the latency and throughput requirements of the service are flexible (delay tolerance) and the contents thus do not need to be delivered to all users via the operator's network: They can be relayed from one user to another in a store-carry-and-forward fashion. Hence, mobility of users can be used as a supplementary transport mechanism to off-load the operator's network and relieve strain on scarce spectrum resources. In this paper, we evaluate the achievable throughputs and spectrum savings of such a mobility-assisted wireless architecture for various mobility patterns and user densities in an area. We also estimate the energy consumption of the mobility-assisted content distribution for the case when Bluetooth radios are used for peer-to-peer communication between users. Our goal is to determine whether mobility assistance brings any advantages for delivering delay-tolerant contents in a wireless network.
