  1. 1. Connectivity management for eneRgy Optimised Wireless Dense networks
  2. 2. Outline  Facts  Motivation  Main objectives and measures of success  Implementation  Main contributions of partners  Concrete project results 2
  3. 3. Facts  Title: Connectivity management for enerRgy Optimised Wireless Dense networks (CROWD)  Call identifier: FP7-ICT-2011-8  Grant number: 318115  Start: 1/1/13  End: 30/6/15 (duration 30 months)  Total cost: 4,460 k€  Total funding: 2,978 k€  Total effort: 443 PM 3
  4. 4. Motivation  Number of wireless users increasing rapidly  Load doubles every year  Current demand is barely supported by existing infrastructure  The solution necessarily entails the deployment of more points of access  Higher density of points of access  Different wireless technologies (heterogeneous deployment)  Current available solutions to handle density are not sufficient  Most existing solutions take local PHY restricted view  Higher layer mechanisms are required for optimal operation  Wireless dense networking can potentially lead to wireless chaos and huge energy waste 4
  5. 5. Motivation  To avoid the implosion of wireless capacity due to increased density we need:  New mechanisms for wireless devices coordination and cooperation  Higher layer algorithms to control and configure network behavior 5
  6. 6. Main objectives  Density-proportional capacity  Throughput scales (almost) linearly with cell density  Traffic-proportional energy consumption  Power consumption reduced by up to ~70%  Mobile user’s QoE  Significantly lower handover blocking probability and end-to-end delay variation experienced by mobile users (compared to a scenario without inter-cell and inter-technology mechanisms)  Significant reduction of the backhaul load (compared to a scenario with static backhaul configuration)  Validation and demonstration  Deployment and successful operation of a test-bed composed of several LTE and WLAN stations together within a dense deployment of base stations and access points  Dissemination and exploitation  High-quality publications in peer-reviewed journal and conferences  Contribution to standardisation 6

  10. 10. Concrete project results 1. New solutions for connectivity management benefiting (rather than suffering) high density in deployments. 2. Novel heuristic approximation algorithms exploiting regional-level information for energy efficient operation. 3. Enhancements at MAC layer for IEEE 802.11 and LTE that use density “as a resource” and exploit it through intra- and inter-technology coordination. 4. Dynamic backhaul reconfiguration strategies that achieve such a consumption that is near proportional to traffic demands. 5. An integrated testbed suitable to validate all the other project results under realistic conditions.11
