3 1. BACKGROUND New discoveries based to pre- Alzheimer disease. (Health report of European initiatives on alzheimers disease, 2010) In Europe, according this health report, from 2005 to 2030 the number of Europeans aged over 65 will increase by 52.3% resulting 40 million additional old citizens, in other words there will be more than 100 million people older than 80 years by Hospital Care Nursing Home Home Care France and UK the figures currently stand at around 60%. Germany 82%, Italy 80% of aging patients stay at home. In many European countries caring for elderly patients is a government and private health priority, and the new approach is to care for people in their own homes wherever possible: France Uk Germany Italy (European Health Report, 2010)

4 1. BACKGROUND CONTINUES. Responding to the above challenges, the European Government Collaborating with Private Sectors and Academic Sectors are dedicated to assist Citizens that are affected by Pre- Alzhemeir Disease (Aging Disease). Some research leading to the results of this work has received funding from European Community s seventh Framework Programme (FP7/ , under grant agreement nº216487), French National Research Association through QuaVADis project EU Funding 7,800, and You can also visit: According to Couet (2011), there are widely accepted imperatives for helping elderly patients living at home (semi)- independently for as long as possible and CompanionAble provide the synergy of Robotics and Ambient Intelligence technologies with their semantic integration to provide for a caregivers assistive environment. This is reconciled by a robot companion (mobile facilitation) working collaborative with a smart home environment.

5 1. BACKGROUND CONTINUES WITH KEY RESEARCH CONTRIBUTORS The next session summarises the key research contributors in Work Collaboration View for FP7/ under grant agreement nº216487, Figure 1: Research Holistic View Work Collaboration View

6 2. PROBLEM STATEMENT - There is an undesirable behaviour that old patients are leaving hospital early because of medical expenses and they still need additional care at their home premises while they recover due to their illness, thus treating a patient at home is less expensive than treating them in the hospital. -Can the existing VoIP tools solve the medical expense crisis and address the problem of seclusion/ loneliness of elderly people with the aim of supporting elderly patients in their daily activities? - There is a need for technological tools that will support and help to deploy the integrated care for old and chronic patients. -Various challenges: managing communication between a distant operator and the robot-companion, graphical user interface of Ekiga is complex for old patients. The necessity of a remote control & a robot operator to control the robot-companion.

7 2. 1. Research purpose and benefits - This research is undertaken to represent the integration of technologies to improve the communication channels like mail, audio, instant messaging, video and etcetera -This is accomplished for elderly patients, family members and medical practitioners using the existing and modified VoIP tools. -This study is important for the reason that it reviews the existing VoIP tools and tries to solve the problem through integration possibilities or find the best corresponding tools that will address the main research objectives. - This study will benefit all people that are interested in Open Source platforms specifically in VoIP Technologies, Telecare platforms, Telemedicine, e-health and will also improve their knowledge on different VoIP tools on how to integrate the existing technologies for communication necessities.

8 2. 2. Research Questions and Examination - This study has been developed in the context of European environment and the main objective is to provide an integrated cognitive assistance. -A) Does the problem of codec s compression and decompression result from SIP clients or SIP Servers? and which tools should be implemented to address such? -B) Can the IP cameras accept orders from PBX server in a form of audio and videos using Real Time Streaming Protocol, if possible are there any delays? - C) For auto-negotiation of 3 rd channel support, would it be possible for robot operator to utilize send and receive data streams either in a form video, sound, s-command from private, public SIP servers to the Robot machine? -D) Does RTP transmits and encapsulates the voice data streams between endpoints for more than one call in a single packet, if possible does it reduces the IP overheard without increases the latency? - E) Does SIP servers have a commitment to support latest version of Ekiga client with modification of GUI implementation, if so are there more specific technical requirements that might needed?

9 2.3 Research objectives - Following section summarises the main objective of the study: 1. Testing and making new working version of Ekiga softphone that support H261, H263, H263+ and H264, this involves integration and cross-compilation processes for both Microsoft windows and Open Source platforms. 2. Integration possibilities of an IP cameras that will support RTSP whereby voice orders can be assigned or dialled to an IP camera and access it using RTSP services 3. Preliminary tests and developing a remote control tab for the Robot companion that will use a 3 rd channel support i.e. sending and receiving orders (audio, video, S-command channels data streams)

10 3. LITERATURE REVIEW We reviewed the current state of VoIP infrastructure or architecture with SIP servers and clients whereby the unified standardized communication solution or infrastructure is explained clearly with system performance. General assessment on different VoIP client applications, assessment on VoIP codec s and identifying possible solutions for Videoconferencing Solution that will act as a communication channel for elderly people, family members and medical Professionals.

12 3. LITERATURE REVIEW Continue SIP Proxy and Redirect Operation

13 3. LITERATURE REVIEW Continue Identifying Possible Solutions: Client Side Ekiga softphone was selected as a SIP client for this project, because it s an Open-Source VoIP application that allows easy modification, unlike other softphones it supports many audio and video codec s selection and is supported both Linux & Windows Platform. The process of testing and making the latest working version of Ekiga that supports H264, H263, and chat functions was part of research objectives. A number of tests were performed for both platforms (Windows and Open Source Platform) VoIP software or hardware normally comes with option to specify the codec s VoIP users prefer to use and this allows making selection between audio, video quality and network bandwidth Usage.

14 3. LITERATURE REVIEW Continue Identifying Possible Solutions: Server Side Kamailio and Dester Asterisk were selected as the SIP/ Master Servers for this project. Asterisk can be thought of as middleware ; it seats between telephony technologies and Telephony applications, providing a generic interface between them (Spencer, 2010). Further objectives of this research was the integration possibilities of an IP camera that can support RTSP modules whereby a SIP request can be directed, assigned or dialled to an IP camera using RTSP services. Each patient will be equipped with a SIP client (Ekiga softphone) and with one or more webcams. The robot will have its own equipment (softphone and IP cameras) and it will have its own SIP line.

15 3. LITERATURE REVIEW Continues Identifying Possible Solutions: Server Side This VoIP solution is composed of three parts: A Master server, A Smart Home and A Remote client. A master server is handling the following: - Asterisk Internet Protocol Private Branch exchange (IPBX) for voice/video communication. - Julius ASR server (it can be hosted by another server). The smart home is equipped with the following: A platform featuring a camera, a display and a VoIP client (ekiga softphone). Various sensors for person monitoring. Internet gateways to support local IPBX. A remote client system: Is a personal machine with VoIP client (Ekiga) or a Smartphone and the Internet access is acting as the main communication media for this platform (Wired or Wireless).
