Continuous monitoring with early detection likely has the potential to provide patients with an increased level of confidence, which in turn may improve quality of life. In addition, ambulatory monitoring will allow patients to engage in normal activities of daily life, rather than staying at home or close to specialized medical services.

Last but not least, inclusion of continuous monitoring data into medical databases will allow integrated analysis of all data to optimize individualized care and provide knowledge discovery through integrated data mining. Indeed, with the current technological trend toward integration of processors and wireless interfaces, we will soon have coin-sized intelligent sensors.

Technical Requirements: 1. Wide variation in data rate, BER, delay tolerance, duty cycle and lifetime 2. Diverse application environments Candidate Technologies Source: M. It uses RFID tags for this purpose. X, or an analyst or a paramedic, or a nurse who is not an intern. Proposed by Chessa et al. Based on Erasure Coding 1.

Proposed by Wang et al. Original encrypted data is broken down into n data shares, with each of them made of a block generated from n,k erasure coding and a share of the secret key using n,k secret sharing 3. These data shares are then distributed among the n neighbouring nodes 4. Dynamic Integrity Check: Each storage node computes and broadcasts an algebraic signature on one data share; one node checks its signature against those by other nodes to detect alterations timely 5.

Based on Constant Data Motion method 1. Proposed by Pietro et al. Found to be very efficient high data survival probability 4. Proposed by Li et al. Each user has a set of roles; patient chooses which roles to grant access to. When a node in WBAN generates data, the AP is built into the Ciphertext; splitting a secret among components belonging to different user attributes; randomized to prevent user-collusion 6.

Effectively implements fine-grained access control Banerjee et al. Thanks a lot! Total views 10, On Slideshare 0. From embeds 0.

Number of embeds 1. Monitoring Techniques The patients possess actuators that work as a drug delivery system for these devices, when the sensors are noticed immediately one can start treatment or trigger medicine by which conditions can be under controlled.

The lower level possesses a set of intelligent nodes or sensors. The second level of architecture possesses personal server that acts as an internet enabled PDA. Wireless medical communications assisting peoples work and replacing wires in a hospital are the applying wireless communications in medical healthcare. The increasing use of wireless networks and the constant miniaturization of electrical devices has empowered the development of wireless body area networks WBANs. In these networks various sensors are attached on clothing or on thebody or even implanted under the skin.

These devices provide continuous healthmonitoring and real-time feedback to the user or medical personnel. The wire-less nature of the network and the wide variety of sensors offer numerous new,practical and innovative applications to improve healthcare and the quality of life.

The sensor measures certain parameters of human body, either externally or internally. Examples include measuring the heartbeat, body temperature or recording a prolonged electrocardiogram ECG. Several sensors are placed in clothes, directly on the body or under the skin of a person and measure the temperature, blood pressure, heart rate, ECG, EEG, respiration rate, SpO2 levels etc.

Next to sensing devices, the patient has actuators which act as drug delivery systems. The medicine can be delivered on predetermined moments, triggered by an external source or immediately when a sensor notices aproblem.

The sensor monitors a sudden drop of glucose, a signal can be sent to the actuator inorder to start the injection of insulin. Consequently, the patients will experiences fewer nuisances from his disease. An example of a medical WBAN used forpatient monitoring. A WBAN can also be used to offer assistance to the disabled. For example, a paraplegic can be equipped with sensors determining the position of the legs or with sensors attached to the nerves.
