W5: First International Workshop on Cross-Layer Operation Aided Multimedia Streaming
W1: International Workshop on Self-Organizing Networks (IWSON)
In recent years, there has been an increasing interest in the self-organizing network (SON) paradigm applied to wireless communications networks. For example, the Next Generation Mobile Network (NGNM) Alliance of leading mobile network operators put strong emphasis on SON as the enabler for efficient operation. SON has been a focus research area for some years, and some SON features have been implemented in wireless networks. Therefore it is timely to gather people with SON interests at a workshop with a concentrated focus on SON for mobile networks. The scope of the workshop is intended to attract both industry and academia, primarily with a focus on 3GPP technologies such as LTE, but other systems can be considered as well.
Papers on the following (but not limited to) topics are invited:
- Self-Configuration: Plug-and-play, Identity Management, Automatic Neighbor Relation setup, Management of non-unique physical cell identities, IP address and VLAN ID management
- Self-Optimization: Random access optimization, Load balancing within and between radio access technologies, Interference management, Mobility Robustness Optimization, Coverage and Capacity Optimization; Node load balancing, Tracking area optimization, Quality of Service Management, Transport Path Optimization Self-Healing: Cell outage detection and compensation, alarm correlation
- Supporting SON functions and technologies: Real-time performance monitoring; Integration of multiple SON functions / SON coordination; Policy-based management
- Field trials and demonstrators: Test bed activities and experiences from field trials; Experience of first deployments of SON features implemented in products

W2: Second Green Wireless Communications and Networks Workshop (GreeNet)
Broadband wireless mobile communications systems are now being widely deployed around the world offering seamless access to data services for smartphones, laptops and other mobile devices. However, there is an increasing gap between the exponentially growing traffic demands and the slow growth of operator revenue from offering these services. Further, there is an increasing awareness of the environmental impact of both wireless networks and the Internet in general. Many operators have promised, as part of their corporate social responsibility agenda, to reduce the Carbon Dioxide (CO2) emissions associated with their networks to improve their future sustainability.
The objective of this workshop is to address these issues by discussing the new technologies that can be exploited to improve the energy efficiency and sustainability of future wireless networks. One major area where advances may be made is in moving towards more heterogeneous wireless networks which employ a mix of network components, such as macro-cell base stations, wireless (fixed and/or mobile) relays, microcells, picocells and femtocells. A second important avenue of research relates to new technologies and algorithms that can be deployed within the radio of each device to reduce energy consumption. Examples of such technologies include efficient radio amplifiers, antennas and Multiple Input Multiple Output (MIMO) configurations as well as new energy saving physical layer techniques and packet scheduling algorithms.
This second workshop will build on the success of the first GreeNet workshop to continue the dialogue between academia and industry on this important emerging research area. Advances that cover new theoretical findings, practical applications and activities relevant to standards bodies such as 3GPP and IEEE 802 bodies are all welcome.
Papers on the following (but not limited to) topics are invited:
- Energy Efficient Wireless Network design : Efficient network architectures; Radio access networks; Network traffic engineering and QoS support; Network operation and management
- Enabling technologies : Physical layer techniques; MAC protocols; Cross-layer optimization; Cognitive networks
- Network components and devices : Low power devices User terminal designs Base station hardware architectures Power management for user terminals and network devices
- Applications of wireless technologies : Wireless networking for smart grid and power management; home working/smart office; Intelligent transport; Machine-to-machine communications; Regulatory issues; Applications to 3GPP/IEEE 802 standards

W3: Cognitive radio and Cooperative strategies for POWER saving (C2POWER)
This workshop looks into the cognitive radio and cooperative techniques for better power efficiency. Cooperative diversity can provide savings in the required transmit power because of the spatial diversity in the system. However, the extra processing and receiving power consumption at the relay and destination nodes for the cooperation gives rise to a trade-off between the gains in the transmit power and the losses in cooperation. Cognitive functionalities on the other hand can be used for context aware transmission schemes for better utilization of the energy.
Papers on the following (but not limited to) topics are invited:
- Cognitive radios and networks
- Cooperative networks and communication
- Energy efficient communication systems and networks
- Context awareness and signalling for power saving strategies
- Short range power efficient communication
- Cooperative relaying for power saving
- Energy efficient cognitive handover procedures and policies
- Energy efficient reconfigurable radios and software defined radios
- Cooperation in homogeneous and heterogeneous networks
- Experimental testbeds and results for energy efficient communication techniques
- Standardization and regulatory aspects and activities for power efficient communication
- Advanced power saving strategies in Bluetooth, DVB-H, UWB, Wi-Fi, WiMAX, LTE considering network cooperation and using femto-cells.

W4: Broadband evolved Femtocell Technologies (BeFEMTO)
In view of current standardization activities in 3GPP and IEEE, changing regulatory landscape and impetus from industrial bodies such as Femto Forum, this workshop focuses on presenting and debating advanced femtocell technologies that have the potential to be considered in future standards such as LTE-A to make the radio access solutions highly efficient with major leapfrog in spectral-efficiency per unit area, while minimizing the transmit power. Specifically, but not exclusively, the workshop proposes to address the following issues:
- Optimisation of Radio Access
- New generation of baseband and radio frequency techniques
- Smart interference management
- Self-configuration and self-optimisation techniques
- Network management and architecture
- Field Trials / Test-beds / Regulatory issues

W5: First International Workshop on Cross-Layer Operation Aided Multimedia Streaming
The object of the workshop is to discuss innovative solutions enabling enhanced video streaming for point to point and point to multi-point transmissions in an IP based wireless heterogeneous system, based on cross layer adaptation of the whole transmission chain. Many areas of improvements classified in the following in four categories are considered in the workshop: i) applications for content delivery; ii) networking; iii) radio access; iv) cross-layer solutions. Indeed, today's approach, relying on traditional separation approaches and focussing on services delivered over homogeneous networks, does not allow to meet the on-going demands to maintain the required Quality of Service (QoS) for each of the users, who have different needs and requirements. This workshop looks into solutions allowing the applicability of a cross-layer design approach to the end-to-end multimedia streaming.
- Cross-layer design
- Multimedia streaming over wireless networks
- Quality assessment
- Point to multipoint video communication
- Signaling for cross-layer communication
- System adaptation and control
- Media adaptation to wireless delivery
