WeCARE(WSN enabled Home Care): Accidental falls threaten the lives of people over 65 years
of age and can be overcome with quick action for saving lives.
Old people who live alone and those who have chronic
diseases constitute the main risk groups. Fast and effective
detection of falls will increase the quality of life of these
people. In this project, using accelerometers together with a
video sensor, multimodal fall detection mechanisms are investigated.
PERA (PERsonal Assistance): In the PERA project, a complete location-based system with multimedia services is proposed. The system enables its users to have voice and video sessions in “all IP” environment. A new concept, named “Location Based Presence (LBP),” is introduced in PERA. LBP supports a new package of services such as finding the nearest friend, emergency call (911), asset tracking and management, route finding, and service point matching.
WLAN Tracker: In the WLAN Tracker project, locations of Wi-Fi capable mobiles are determined within 2-6 meters by only using the existing Wi-Fi infrastructure and without using GPS. A full prototype based on LINUX OS computers is developed and simple text based location-based services are offered in NETLAB and in the Computer Engineering Department Building.
MAST (Mobile Application Services and Testbed): The aim of the MAST project is to design and implement a Mobile IP testbed over which other projects developed in NETLAB can be tested. In MAST, the nodes can be configured and tested for the CMPE and/or MAST domains using DHCP. Two SIP clients have been developed in MAST using C# and C++. MP3 and video streaming services are also provided over the MAST testbed. Also, several subprojects within MAST cover the area of secure interoperability of 2G, 2.5G, 3G networks and wireless LAN’s, and formal modeling of mobility and secure routing in wireless/mobile networks.
WIDE (Wireless Information Delivery Environment): In the WIDE project, location-based information is provided to wireless capable PDAs and notebook computers. The aim of the project is to transfer popular local data to multiple clients based on the pre-registered user profile after user authentication. Possible scenarios are the distribution of lecture notes, problem solutions, and announcements in a campus environment, traffic condition and local maps at traffic lights, or movie fragments and schedules in a film festival. WIDE project uses the MAST testbed.
ASMA: The aim of the ASMA project is to develop a high performance network-based multicomputer system for numerically intensive applications such as computational fluid dynamics and earthquake engineering. The system is implemented as a 100Mbps switched Ethernet based Beowulf cluster. Currently, about 30 nodes exist in ASMA. ASMA is shared among several departments of the university, such as chemistry, civil engineering and mechanical engineering.
AGORA: AGORA provides closed voting, security, and authentication. Although the AGORA system is developed for elections and voting, it can also be used for multiple-choice surveys.
NGWS (Next Generation Wireless Systems) Testbed: The NGWS testbed emulates several wireless systems (2G, 3G, WLAN, satellite, etc.) using only WLAN cells. The aim of the project is to create a unified testbed to study and evaluate various schemes developed for the heterogeneous environment of NGWS. Besides providing a tool for testing, this project will also help NETLAB students improve their skills for UNIX kernel-level programming and developing large and flexible team projects. The project is currently in design phase.
ARAM Testbed (Integration of Direct Broadcast Satellites into the Digital Battlefield Using Low Earth Orbit Satellites): The aim of this project is to design, develop and integrate the Adaptive Resource Allocation and Management (ARAM) system within the use of a Digital Battlefield Broadcast System. We designed, developed, tested and optimized the ARAM software, and resolved the quality of service (QoS) problems within the network.
RCML (Reduced Complexity Maximum Likelihood Algorithm): In order to reduce the complexity of the optimum multiuser detection, in this project we investigate a Reduced Complexity Maximum Likelihood (RCML) algorithm that includes a set of novel certain boundary rules and characteristics. We are currently working on devising a suboptimum detector based on the RCML algorithm.
REPAS (Remote Protocols and Applications Laboratory): In this project, we designed and developed the Remote Protocols and Security (REPAS) Laboratory to fill a critical gap in today’s university operated computer facilities. REPAS Lab offers the proper and stimulating environment to allow students and researchers to do their work with as much ease and confidence as online banking. We are currently investigating the wireless connection mechanism of the REPAS Lab for provisioning a reliable e-learning environment.
Mil-Chat Software (Design and development of a new hash based instant messenger): In this project, we design and develop a new secure-chat system for nodes operating with hierarchy. In the proposed Mil-Chat system, we first follow existing AES (Advanced Encryption Standard) block encryption standard and a new key distribution algorithm. Performance measures and analysis will be investigated. Additionally, the testbed will be used to study and support ongoing researches on “secure-chat” and “security in the next generation satellite networks.”
Commitment Protocols: This project studies methods to specify and execute multiagent protocols flexibly. To achieve this, the actions in the protocols were given a meaning based on the commitments of participants to one another. Creation and manipulation of the commitments represent the execution of a protocol. Using such representations, this project showed how different protocols can be enhanced by automatically generating alternative protocol runs.
SEE-GRID (South Eastern European GRid-enabled e Infrastructure Development) is a European Commission 6 th Framework Programme Specific Support Action project and it has started in May 2004. The project leader is GRNET, Greece and participants are CERN, Switzerland and national representative organizations from Turkey, Bulgaria, Romania, Hungary, Albania, Bosnia-Herzegovina, FYR of Macedonia, Serbia-Montenegro and Croatia. Turkish representative organization is TUBITAK-ULAKBIM, Bogazici University, Istanbul Technical University and Bilkent University act as third parties to carry out the actual work. NETLAB carries out all work on behalf of Bogazici University, lead by Prof. M. Ufuk Caglayan. The project aims to assist the participation of the consortium states in the pan-European and worldwide Grid initiatives by establishing a seamless and interoperable pilot-Grid infrastructure, that will enable migration and testing of Grid middleware components, deployment, adaptation and testing of Grid applications, integration of available pilot resource centers and promotion of awareness in the region regarding Grid developments, thereby easing the digital divide.
OPNET Supported Projects: NETLAB is sponsored by the University Programs offered by OPNET. Several research projects are carried out by using the OPNET simulator. These projects are:
- Quality of Service Provisioning in Wireless Multimedia Sensor Networks
- Ad Hoc Multicasting in Mobile Multimedia Networks
- Energy Saving Through Load Balancing in Wireless Sensor Networks
- Quantifying Energy Saving Using Multi-Hop Links in Wireless Sensor Networks
- Large Scale Multiple Sink Wireless Sensor Network Design
- Routing in a LEO Network Using Min Flow Max Residual Path in a Routing Set
