Wireless sensor network
- 1. As the world's population ages, those suffering from diseases of the elderly will increase. In-home and nursing-home pervasive networks may assist residents and their caregivers by providing continuous medical monitoring, memory enhancement, control of home appliances, medical data access, and emergency communication. Researchers in computer, networking, and medical fields are working to make the broad vision of smart healthcare possible. The area of wireless sensor networks for medical applications there are three main research directions: power consumption optimization, security method development for medical data transmission, management of the wireless sensor networks. Wireless physiological data monitoring system uses a radio channel to send real time vital sign data from wearable biomedical sensor devices to a coordinator. Patients can wear wireless devices that sense Physiological conditions and send the sensed data to their doctors in real time. Wireless health monitoring systems have several advantages compare to wired health care equipment. First, patients no longer waste waiting time to meet their doctor. Moreover, the use of wireless healthcare systems outside the hospital helps to save the healthcare cost for care providers. It also allows many patients to work while they are still under their doctor’s care. Second, such systems can alert any medical emergency if specific vital signs change drastically. The fundamental elements of future medical applications (integration with existing medical practice and technology, real-time and long-term monitoring, wearable sensors and assistance to chronic patients, elders or handicapped people), our wireless system will extend healthcare from the traditional clinical hospital setting to nursing and retirement homes, enabling tableware without the prohibitive costs of retrofitting existing structures. The advantages of a WSN are numerous for smart healthcare, as it provides the following important properties: -time and always-on
- 2. -organization Background: Wireless Sensor Networks are a key technology for ambient assisted living.A reasonable use case is the observation of vital parameters, e.g. blood pressure, respiration and motion. Using a mobile device (e.g. PDA or Mobile), the parameters can be retrieved and processed. ADVANTAGES lifecycle costs. or expensive repairs, and circumvent complete failure of the monitored structure. ture. monitored structure. Body sensor network systems can help people by providing healthcare services such as medical monitoring, memory enhancement, medical data access, and communication with the healthcare provider in emergency situations through the SMS or GPRS . Continuous health monitoring with wearable or clothing-embedded transducers and implantable body sensor networks will increase detection of emergency conditions in at risk patients. Not only the patient, but also their families will benefit from these. Also, these systems provide useful methods to remotely acquire and monitor the physiological signals without the need of interruption of the patient’s normal life, thus improving life quality . Although present systems allow continuous monitoring of patient vital signs, these systems require the sensors to be placed bedside monitors or PCs, and limit the patient to his bed. But now, there is no relation between the sensors and the bedside equipment due to the wireless devices and wireless networks. These systems do not require the patient to be limited to his bed and allow him to move

In most cases, health monitoring will be done by infrastructure-oriented wireless networks such as commercial cellular/3G networks or wireless LANs. But, the coverage of the infrastructure-oriented networks changes with time or location. Sometimes, the coverage of wireless network is not available, or the coverage is available but we cannot access to the network due to a lack of available bandwidth. So, with these problems and restrictions, continuous health monitoring is not possible and emergency signals may not be transmitted from a patient to healthcare providers. Under these conditions, we can reach to continuous health monitoring by using ad hoc wireless networks that can transmit vital signs over a real-time transmission. In most systems the health data from multiple patients can be relayed wirelessly using multi-hop routing scheme to a base-station . Today in the health department we have a urgent requirement for wireless data transmission . Today I hospitals rooms are fully controlled by automatic sensors .These sensors and machine will send the data to the doctor or nurse for monitor the patient . In this all process we have a one important thing . That is data security . For example in a hospital /road a patient is in room / ambulance .all medical machines are working correctly and dispatching the data correctly I digital form . But in on the way data destroyed and convert in the another then in the hospital doctor /nurse room data will send incorrect . So in this case this can be very dangerous for human because doctor is not reading the data which is send by the health sensor . Doctor Is reading the incorrect value . We have a requirement a system in which we can transfer wireless data In a way in which data lost will be minimize . So we are designing a wireless system in which data will transfer through wireless sensor without any losses of data . We are designing a system in which we will show that 1:- how many data is sending by patient room . 2:- how many data is receiving at doctor room and nurse room .
- 4. In this all process we are reducing the percentage of data lost between these process. PART 1 PART 2 PART 3 My work for 2 month:- Medical Wireless sensor network (MWSN) Transmitter Part tr Doctor / nurse room Receive the data In the previous two months I have been created a row material regarding to all three parts. Part 1:- Health Wireless sensor network :- We will design a health wireless sensor network which will take the data from human body and then transmitted it wireless. We will send the data in packets . Patient Body Health wireless sensor Data Packets transmission Data Lost between transmitter and receiver
- 5. Part 2 :- Doctor / nurse room Receive the data :- Data will be received by a receiver in a doctor /nurse room . The data will be received in the packets form. Part 3:- Data Lost between transmison and reciver :- The graph will show that how many data is destroying . In the final result of our thesis we will show a graph like a given below as a example . In this we have been declare that data is sending and at receiver point data is receiving . third graph is showing that how many data id destroying . so we will reduce the data lost graph . so that data will send accurately and can be received accurately so that doctor and nurse can get exact monitoring of the patient . 100% 90% 80% 70% 60% 50% 40% 30% 20% 10% 0% Software :- This work can be implemented at two software . 1:- Matlab 2:- CISCO Packet tracer .
