نظراً للتطور التقني أصبحت شبكات الحساسات اللاسلكية WSN واسعة الانتشار، و أصبحت تستخدم في شتى المجالات المدنية و العسكرية و البحث العلمي. و مثل كل الشبكات فهي عرضه للاختراق، لكن تركيبتها البسيطة (قدرة المعالج و الذاكرة) تفرض إيجاد تقنيات لصد الهجمات غير التقنيات المستخدمة في الشبكات العادية. تهتم معظم أبحاث الأمان في شبكات الحساسات على سرية و سلامة البيانات، في هذا البحث سنقوم بالتركيز على الهجمات التي تستهدف موارد الطاقة و التي يطلق عليها اسم Denial of sleep (DoS) رفض الدخول بوضع الإثبات، و هي من أخطر الهجمات التي يمكن أن تتعرض لها، إذ يقوم المهاجم بإجبار الحساسات على العمل بشكل مستمر حتى تستنفد كامل مدخراتها. قمنا في هذا البحث باستعراض مسببات هدر الطاقة في WSN و تصنيف الهجمات التي تستهدف منابع الطاقة و قمنا ببناء أنموذج محاكاة لتحليل استجابة البروتوكول B-MAC (الأوسع انتشارأ) لهجمات رفض الدخول في وضع الإثبات.
Wireless sensor network have become widely used in many civil and military issues. Like all other network, it is exposed to attacks but its simplicity structured (CPU & memory) prevent the traditional defense technic to be applied, so they need a special for defense. Most security researches focus on data righteousness and privacy, in this research we focus on attacks that aimed to the power resources which are referred as Denial Of Sleep attacks (DoS), in this attacks the attacker try to keep the sensor in active phase causing the power source to be drained very quickly so that it is a very dangerous attack. In this research we reviewed the sources of energy Loss in wireless sensor network and classified the attacks that target the power resource, we built a simulation module to analysis the B-MAC protocol response to denial of sleep attacks.

The reducing of energy consumption for various nodes in wireless sensor networks
plays an important and essential role in the prolonging of the life of these networks. In
order not to be the energy consumption in some node is very high and in other
s is less or
very low, the choice of distribution algorithms of the nodes role, as a router node or
terminal nodes, and switching between them, plays an important role in prolonging the
lifetime of wireless sensor networks.
This paper presents an algorithm for the distribution of WSN nodes roles, including
allowing the applying of many tree patterns to a single network. This offers the potential to
alter the network nodes roles centrally by coordinator and switching between these tree
patterns whenever the need arises according to the indicators of energy consumption in the
nodes. The results show that the use of the algorithm leads to a significant improvement in
the network life ranges between 2 and 4 times, according to the allowing the nodes to sleep
and wakeup, or not, for different transmission rates where the scenarios have been tested
for ZigBee based wireless sensors networks using NS-2 simulator.
Wireless Sensor Networks (WSN) have applications in many different areas of life, such as health care, environmental monitoring, and military and economic areas and in industrial automation and many other applications.
The development of these net
works and the improvement of their performance occupy an important place of interest in research centers and specialized scientific institutes. The interest in these structures as a way to improve the performance of these networks leads to good results in this area. The cluster structure is one of the most important structures that have received increasing attention over recent years.
This research suggested a modification of the structure of the cluster tree WSN dividing clusters into sub-groups, and each group of these sub-groups operates like a tree from a small amount of nodes. The results that have been obtained by means of simulation indicate a significant improvement in terms of reducing energy consumption and thus an increase in the lifetime of the network, as compared to traditional cluster tree WSN. But that was at the expense of slightly lower rates of transmission and delivery ratio in the nodes of these networks. This leads us to recommend using this method to build the networks used to monitor protected agriculture and other networks with low transmission rates.
The dynamic clustering-based hierarchical routing protocols are one of the methods
used to save energy and increase the lifetime of wireless sensor networks, however, that
most of the researches are neglecting the energy expended in election of the
heads and
formation of clusters in the network.
In this paper, we examine the overhead energy caused by hierarchical routing
protocols based on dynamic clustering and study its impact on the stability period of the
wireless sensor networks. Also, we proposed a solution to limit this energy by reducing the
consumed energy in election of heads and clusters formation operations. It is shown
through the simulation results that the energy consumed in LEACH setup phase decreases
the stability period of these networks and increases the number of dead nodes. And the use
of the proposed solution reduced the energy consumption during the election of the heads
and the formation of clusters clearly compared to the normal way followed in LEACH,
which has increased stability period and the number of live nodes in the network.
Routing protocols play an essential role in meeting the quality of service
requirements in the network, but achieving these requirements may require frequent send
and receive operations to build and maintain routing tables, which consume sensors
r
esource If we take into consideration the limitations of wireless sensor networks in terms
of the amount of available energy and storage capacity.
In this research a performance comparison of the on-demand Distance Vector
Routing protocol AODV and Hierarchical Routing protocolHR was carried out in terms of
the packet delivery and loose rate, delay and jitter, and the amount of expended energy in
the Wireless sensor network operates according to IEEE802.15.4 standard in cases where
some of sensors get out of work for limited periods of time.
The results showed that the hierarchical routing protocols perform better in terms of
delay time and transfer rate and the amount of consumed energy than on-demand Distance
Vector Routing protocol routing protocol, but suffer larger packet loss due to routing path
corruption as a result of sensors crashes.
In this PAPER, we perform a study and extensive comparative between
the well-known link quality estimators and CTP, a tree-based routing
protocol provided by TinyOS for different network topology and simulate
it using TOSSIM simulator to evaluate
the performance of these
estimators.
