Patients in hospitals have issue with health instrumentality that's connected with wires to their body. Wired health instrumentality restricts the quality of the patient. Moreover, health caretaker’s area unit compelled to work the instrumentality and take the measurements. Hence, wireless observance of patient is incredibly effective resolution thereto drawback. The most target of this study was to analysis the present trend and prospect of wireless observance of patients within the hospitals. This study conjointly aims to create the epitome system to implement wireless observance. Additionally to that, this thesis conjointly studies most fitted technique for building the foremost effective wireless observance system.

This work presents the design and optimization of an antenna with defected ground structure (DGS) using characteristic mode analysis (CMA) to enhance bandwidth. This DGS is integrated with a rectangular patch with circular meandered rings (RPCMR) in a wearable format fully using textiles for wireless body area network (WBAN) application. For this integration process, both CMA and the method of moments (MoM) were applied using the same electromagnetic simulation software. This work characterizes and estimates the final shape and dimensions of the DGS using the CMA method, aimed at enhancing antenna bandwidth. The optimization of the dimensions and shape of the DGS is simplified, as the influence of the substrates and excitation is first excluded. This optimizes the required time and resources in the design process, in contrast to the conventional optimization approaches made using full wave “trial and error” simulations on a complete antenna structure. To validate the performance of the antenna on the body, the specific absorption rate is studied. Simulated and measured results indicate that the proposed antenna meets the requirements of wideband on-body operation.

The increasing use of wireless communication and the continuous miniaturisation of electronics devices have brought about the concept of Wireless Body Area Network (WBANs). In these types of networks, the sensor node operates in close proximity to the body and also the wireless nature of the system presents various novel, real-time and new methods to improve health care delivery. The sensor is capable of measuring any parameter which it has been designed to read, for example the heartrate and the body temperature. This paper presents a review of the concept of WBANs with a focus on the mechanism of data communication over the wireless medium. Further, it examines ways to power such devices, in particular focusing on minimisation of energy requirements, thereby reducing maintenance demands and contributing to making the environment ‘greener’.

Wireless Body Area Network (WBAN) is a collection of miniaturized sensing nodes and coordinator nodes. These sensing nodes are placed in, on and around the body for uninterrupted monitoring of physiological data for medical applications. The main application carrier of WBAN is the human body and due to human body movement and physiological changes, the WBAN traffic fluctuates greatly. This network traffic fluctuation requires good network adaptability. In addition to traffic fluctuations, energy consumption is another key problem with WBANs as sensing nodes are very small in size. This paper design a reliable protocol by extending the MAC protocol for reducing energy consumption, PAP algorithm to decide data transmission rate and JOAR algorithm to select the optimize path for the data transmission. The performance of the algorithm outperforms other state of art algorithms to shows its significance.

Exercise intensity is classified into vigorous, moderate and low type of exercise intensity. They are classified based upon the amount of energy used by the body while doing the activity. Vigorous or over exercise may leads to over tiredness and physical problem while low or lack of exercise may leads to unhealthy lifestyle. Therefore, moderate exercise or regular physical activity in daily life helps to improve overall health and fitness and reduces the risk for many chronic diseases.

PurposeThe purpose of this paper is energy consumption and security. To extend the sensor’s life span, saving the energy in a sensor is important. In this paper, biosensors are implanted or suited on the human body, and then, transposition has been applied for biosensors for reducing the sensor distance from the sink node. After transposition path loss has been calculated, security is maintained and also compared the results with the existing strategies.Design/methodology/approachNowadays, one of the most emergent technologies is wireless body area network (WBAN), which represents to improve the quality of life and also allow for monitoring the remote patient and other health-care applications. Traffic routing plays a main role together with the relay nodes, which is used to collect the biosensor’s information and send it towards the sink.FindingsTo calculate the distance and observe the position, Euclidean distance technique is used. Path loss is the main parameter, which is needed to reduce for making better data transmission and to make the network stability. Routing protocols can be designed, with the help of proposed values of sensors locations in the human body, which gives good stability of network and lifetime. It helps to achieve as the less deplete energy.Originality/valueThis scheme is compared with the two existing schemes and shows the result in terms of parameter path loss. Moreover, this paper evaluated a new method for improving the security in WBAN. The main goal of this research is to find the optimal sensor location on the body and select the biosensor positions where they can get less energy while transmitting the data to the sink node, increasing the life span in biosensors, decreasing memory space, giving security, controlling the packet complexity and buffer overflow and also fixing the damages in the existing system.

The purpose of this research was to improve the performance of a wireless body area sensor network, operating on a person in the seated and standing positions. Optimization-focused on both the on-body transmission channel and off-body link performance. The system consists of three nodes. One node (on the user’s head) is fixed, while the positions of the other two (one on the user’s trunk and the other on one leg) with respect to the body (local coordinates) are design variables. The objective function used in the design process is characterized by two components: the first controls the wireless channel for on-body data transmission between the three sensor nodes, while the second controls the off-body transmission between the nodes and a remote transceiver. The optimal design procedure exploits a low-cost Estra, which is an evolutionary strategy optimization algorithm linked with Remcom XFdtd, a full-wave Finite-Difference Time-Domain (FDTD) electromagnetic field analysis package. The Pareto-like approach applied in this study searches for a non-dominated solution that gives the best compromise between on-body and off-body performance.

AbstractHuman Body Communication (HBC) is an alternative to radio wave-based Wireless Body Area Network (WBAN) because of its low-loss, wide bandwidth leading to enhanced energy efficiency. HBC also shows better performance in terms of physical security as most of the signal is confined within the body. To obtain optimum performance and usability, modeling of the body channel plays a vital role. Out of two HBC modalities, Galvanic HBC has the promise to provide lower loss compare to Capacitive HBC for shorter channel length. In this paper, we present the first lumped element based detailed model of Galvanic HBC channel which is used to explain the dependency of channel loss on the material property of skin, fat and muscle tissue layer along with electrode size, electrode separation, geometrical position of the electrodes and return path capacitance. The model considers the impedance of skin and muscle tissue layers and the effect of various coupling capacitances between the body and Tx/Rx electrodes to the Earth-ground. A 2D planner structure is simulated in HFSS to prove the validity of the proposed model. The effect of symmetry and asymmetry at the transmitter and receiver end are also explained using the model. The experimental results show that, due to the mismatch at the transmitter and receiver side, the loss increases gradually with channel length and saturates to a finite value as channel length becomes significantly longer compare to the transmitting or receiving electrode pair separation.
