يعد التعقب باستخدام شبكات الحساسات اللاسلكية من التطبيقات التي تشهد نمواً كبيراً. و نظرا لمحدودية شبكات الحساسات اللاسلكية من حيث مصدر الطاقة، تستمر الأبحاث لتحسين طرق نقل المعلومات و توجيهها بما يضمن استهلاكاً أقل للطاقة. لذلك قمنا في هذا البحث بتحسين طريقة توجيه معلومات موقع الهدف في الشبكة و ذلك بتقديم خوارزمية جديدة، تستفيد من مفهوم العنقدة في شبكة الحساسات اللاسلكية، مع إضافة إمكانية التفاعل ما بين الحساسات الحقلية التي تنتمي لعناقيد مختلفة، حيث لا يمكن التفاعل فيما بينها في الحالة التقليدية لعمل الشبكات العنقودية، و ذلك اعتماداً على بارامتر شدة الإشارة المستقبلة من الهدف في الحساسات لغاية التخلص من تكرار نقل نفس المعلومة، مما ينعكس إيجاباً على عمر الشبكة و الحصول أيضاً على إشارة أكثر دقة لموقع الهدف. قمنا بتطبيق الخوارزمية المقترحة و إظهار نتائجها باستخدام محاكي OPNET الذي يعد من أفضل المحاكيات في مجال الشبكات بأنواعها المختلفة.
The tracking using wireless sensor networks is one of the applications that are experiencing significant growth. Due to considerations of wireless sensor networks in terms of limited energy source, researches continue to improve methods of routing and transforming information to ensure lower power. Therefore, we have in this research improved the routing of target location information within WSN by providing a new algorithm, which takes advantage of the concept of clustering for wireless network sensors, with the addition of the possibility of interaction between field sensors that belong to different clusters, where in other cases, they cannot interact with each other in the traditional case of cluster networks. to get rid of repeating the same information transfer, we depend on the parameter intensity of the received signal from the target in the sensors, which will reflect positively on the network age, and give a more accurate indication of the target site. We have implemented the proposed algorithm and showed the results of using the simulator OPNET which is one of the best simulators in the field of various types of networks.

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.
The low cost, ease of deployment has exposed WSNs an attractive choice for numerous applications,like environmental monitoring applications , security applications, real time tracking, and so on.
But in reality, these networks are operated on batte
ry with limitations in their computation capabilities, memory, bandwidth ,so they called networks with resource constrained nature, and this impels various challenges in its design and its performance.
Limited battery capacity of sensor nodes makes energy efficiency a major and challenge problem in wireless sensor networks. Thus, the routing protocols for wireless sensor networks must be energy efficient in order to maximize the network lifetime.
In this paper we simulated LEACH,SEP,DEEC,TEEN routing protocols and evaluated their performance by comparing with DT routing protocol in Homogeneous and Heterogeneous Wireless Sensor Networks on MATLAB.
Mobile Wireless Sensor Network (MWSN) is an emerging technology for attraction of
researchers with its research advantage and various application domains. Due to limited
resources of sensor nodes such as transmission power, communication capability
and
size of memory, data aggregation algorithms are the most practical technique that reduces
large amount of transmission in this network. Security is an important criterion to be
considered because, wireless sensor nodes are deployed in a remote or hostile
environment area that is prone to attacks easily. Therefore, security are essential issue
for MWSN to protect information against attacks.
In this research, we offered an algorithm of secure data aggregation in MWSN based on
pair-wise keys technology and hash function. We studied important parameters such as
execution time, end-to-end delay and number of storied keys. Results showed that
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.
In this research we study some of the most Bio-inspired MAC
protocols widely used in WSNs. we select the protocols which
depends on ant colony optimization behavior (ACO), bee colony
optimization behavior (BCO) and particle swarm optimization.
