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 others 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.

Critical review
دراسة نقدية: على الرغم من النتائج الإيجابية التي أظهرها البحث في تحسين زمن حياة شبكات الحساسات اللاسلكية باستخدام خوارزمية توزيع الأدوار، إلا أن هناك بعض النقاط التي يمكن تحسينها. أولاً، لم يتم التطرق بشكل كافٍ إلى تأثير العوامل البيئية الخارجية على أداء الخوارزمية، مثل التداخل الكهرومغناطيسي أو التغيرات في الطقس. ثانياً، قد تكون الخوارزمية معقدة من حيث التنفيذ العملي في البيئات الحقيقية، حيث تتطلب إدارة مركزية دقيقة وتنسيق مستمر بين العقد. ثالثاً، لم يتم اختبار الخوارزمية على أنواع مختلفة من الشبكات أو في سيناريوهات تطبيقية متنوعة، مما قد يحد من تعميم النتائج. أخيراً، يمكن تحسين البحث بإضافة دراسات مقارنة مع خوارزميات أخرى مشابهة لتقديم صورة أكثر شمولية عن الفوائد والتحديات.

Many wireless sensor network applications like forest fire detection and environment monitoring recommend making benefit from moving humans, vehicles, or animals to enhance network performance. In this research, we had improved our previous protoco l (Dynamic Tree Routing DTR) in order to support mobility in a wireless sensor network. First, we had mathematically approximated the speed threshold for mobile sensors, which enables them to successfully associate with nearby coordinators. Second, we test our (MDTR) protocol in a network with mobile sensors sending packets toward network's main coordinator. The simulation results obtained from network Simulator (NS2) showed a good approximation of speed threshold, and good performance of MDTR in term of delay, throughput, and hop-count compared with AODV and MZBR Protocols.

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.
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.
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
