تعد الرعاية الصحية عن بعد تقنية واعدة في فعاليتها ودقتها وانتشارها، ونظراً لأهمية العناية والمراقبة الطبية في المناطق التي تفتقر لوجود كوادر طبية كافية أو يصعب الوصول إليها من جهة، ونتيجة لارتفاع تكاليف التطبيب خصوصاً من أجل كبار السن من جهةٍ أخرى. نالت شبكات حساسات الجسم اللاسلكية WBAN اهتماماً كبيراً من البحث والتطوير خصوصاً نتيجةً للتطور الهائل في شبكات الحساسات اللاسلكية والالكترونيات الحديثة التي أحدثت حساسات ذكية صغيرة الحجم قابلة للتموضع داخل الجسم أو عليه. سنتطرق في بحثنا هذا إلى استخدام هذه الشبكات الحديثة في المجال الطبي وتحديداً مراقبة المرضى في المشافي حيث أن المراقبة المستمرة وضبط البارامترات الحيوية هنا ذات أهمية كبيرة على حياة المرضى. تقوم الفكرة الأساسية على نشر مجموعة من الأجهزة الحساسة بتشكيل معين على جسم المريض، ولهذه الأجهزة عدة وظائف لأداء العمل المتكامل المتمثل بقياس وتحسس البارامترات المهمة، وإرسالها على شكل معلومات إلى عقدة منسقة تقوم بتجميع هذه المعطيات وإرسالها الى محطة رئيسية تقوم بمعالجة هذه المعلومات واتخاذ القرار المناسب، ومن ثم إرسال هذا القرار إلى الأجهزة المنتشرة والتي تترجم هذا القرار على أرض الواقع ليتم ضبط البارامترات من جديد.
Telehealth is a promising technology in its effectiveness, accuracy and prevalence, and given the importance of medical care and monitoring in areas that lack adequate medical staff or are difficult to access on the one hand, and as a result of the high costs of medical treatment, especially for the elderly on the other hand. Wireless body sensor networks (WBAN) has received a lot of attention from research and development, especially as a result of the tremendous development in wireless sensor networks and modern electronics that have caused smart small size sensors that can be positioned inside or on the body. In our research, we will discuss the use of these modern networks in the medical field, in particular patient monitoring in hospitals, as continuous monitoring and control of vital parameters here are of great importance to patients' lives. The basic idea is to publish a group of sensor devices with a specific formation on the patient’s body, and these devices have several functions to perform the integrated work of measuring and sensing important parameters, and send them as information to a coordinated node that collects these data and sends them to a main station that processes this information and makes decision. Then, it sends a message of this decision to the deployed agencies that translate this decision in order to adjust the parameters again.

The wireless sensors network applications are widely used in health monitoring systems. In fact, they contribute to the qualitative development of these networks so as to ensure the tireless clock surveillance, and improve and regulate the quality of
monitoring. Associated with improving the performance of wireless medical sensor networks WMSN is improving data transfer mechanism which is one of the most important areas of interest to research and study in recent times.
Hence the importance of this research lies in the study of the structures of wireless sensor networks that can be used to control the wards in hospitals, health centers and monitoring care. The research also draws necessary recommendations and suggestions for the selection of appropriate medical wireless sensors networks structure and proposees appropriate medium access control mechanism in order to build networks of different sizes.
This has been done by proposing appropriate scenarios for surveillance applications to perform simulation that is similar to the working conditions of the networks. This can ensure the transfer of nodes data to the main access point and can give an opportunity to study the impact of network architecture and how to use the data transfer technology, specifically the use of ZigBee technology, both with beacon mode enabled inenabled. Improvement was evaluated based on the basic parameters in such networks, such as throughput, the time delay, and the delivery ratio. The study found a set of recommendations regarding the size of the network, the type of structure and the mechanism used to access medium.
The use of wireless sensor networks to monitor and control the precise agriculture is one of the areas which received broad concern in recent times, for the services, facilities and the reliability provided by these networks on the monitoring and con
trol level.
This research contributes to the study of the application of this technique in greenhouses deployed over large areas in our country. It offers solutions for networks of monitoring and control, in real time, and ensures a good performance according to the essential evaluating criteria, such as reducing the time-delay, and increases throughput, increases the delivery ratio of packets, and reduces the number of packets lost along with increased network load.
In order to do that, a number of scenarios are proposed. These scenarios are similar to the reality of the construction and operation of the greenhouses in our region relying on ZigBee technique. Wireless sensors networks of these scenarios have been tested, using simulation in order to make conclusion and recommendations to guide the work while installing such networks in place to work as their best for different areas and a large number of lounges
Wireless sensor networks (WSNs) are often deployed by random bestrewing
(airplane bestrewing for example). A majority of nodes cannot obtain their coordinate
beforehand. Therefore, how to obtain the position information of unknown nodes, which is
called localization problem, has become a hot topic in WSN.
Without position information, WSN cannot work properly. Global Position System
(GPS) is the most extensive and mature position system at present. But because the nodes
usually have the shortcoming of high expenditure, large volume, high cost and require
settled basal establishment, therefore, the GPS is inapplicable for the low-cost selfconfigure
sensor networks, and also it is impossible to install GPS for each sensor node. In
this paper, we will study localization mechanisms (which is not based on GPS) used in
WSN, and will test the effectiveness of using MUSIC algorithm in determining the signal
arrival angel depending on the SDMA- technology and ESPAR antenna.
The location of wireless sensor nodes located in the center is necessary for applications
where information about the site is important information such as security, protection,
object tracking and other applications.
localization algorithms are c
lassified into two types: Range-based and Range-free. The
study focused on Range-free localization algorithms because they are less expensive in
terms of hardware requirements.
The MATLAB was used to simulate the algorithms, whose performance was evaluated by
changing the number of network nodes, the number of Anchor nodes, and the contract area
of communication in order to illustrate performance differences in terms of localization
error.
The results showed the superiority of the amorphous algorithm, achieving high localization
accuracy and lower cost for the number of Anchor nodes needed to achieve a small error.
Wireless Sensor Networks (WSNs) are often deployedrandomly;this makes the
positiondetermination of deployed nodes a very difficult issue, which is called localization
problem. The importance of node localization information becomes from the facilit
y of
routing operation and the network control, that makes the network works correctly.
Nowadays, Global Position System (GPS) is appeared as the most important position
system, but it is inapplicable for the low-cost self-configure sensor networks, and also it is
impossible to install GPS for each sensor nodebecause of high cost, large volume and high
complexity required of adding it to nodes, especially for large network.Therefore, a few
number of nodes may be configured with GPS.
In this paper,we will study the localization algorithmAd-hoc Positioning System
(APS) algorithmused inUnderwater WSN, andwill testthe effectiveness of usingitin
determining the node position based on the distance calculated by anchor nodes. These
nodes are the nodes which know their positions.
