يعتبر نظام النشر و الاشتراك (pub/sub) نموذج التواصل الأكثر شيوعاً في الانظمة الموزعة على نطاق واسع ، حيث نشهد في أيامنا هذه انتشاراً متزايداً لاستخدام شبكات النشر و الاشتراك في مجموعة واسعة من التطبيقات تبدأ في مجال الصناعة و المجال الأكاديمي العلمي و الطبي و نشر البيانات و ادارة العمليات التجارية و لا تنتهي في مجال مواقع التواصل الاجتماعي التي باتت تشغل حيزاً واسعاً من اهتمامات المستخدمين و من عرض حزمة الشبكة المستخدم . تلك التفاعلات تضاعفت بشكل كبير عن الأعوام الماضية و أصبح يتم توليد مليارات الإشعارات اليومية من قبل ملايين المستخدمين على شبكات التواصل الاجتماعي . مما زاد من أهمية البحث في مجال شبكات النشر و الاشتراك و خاصة شبكات الند للند التي كانت تستخدم بداية بروتوكول Scribe لتوجيه البيانات , و منذ ذلك الوقت تم تقديم العديد من التطويرات و التحسينات لإنشاء تصاميم جديدة , و أهمها بروتوكول Polder Cast . يدرس البحث أداء البروتوكولات الأكثر استخداماً لتقييم فعالية كل منها من حيث سرعة نشر الموضوع و سرعة الاشتراك و الموارد اللازمة و توزيع الحمل في الشبكة.
Publish/subscribe (pub/sub) is a popular communication paradigm in the design of largescale distributed systems. We are witnessing an increasingly widespread use of pub/sub networks for a wide array of applications in industry , academia , financial data dissemination , business process management and does not end in social networking sites which takes a large area of user interests and used network baseband . Social network interactions have grown exponentially in recent years to the order of billions of notifications generated by millions of users every day. So It has become very important to access in the field of publishing and subscription networks, especially peerto- peer (P2P) networks that used at first the Scribe data routing protocol. Since then, many developments and improvements have been made to create new designs. One of these designs is the Polder Cast protocol. The research studies most used protocols performance to assess the effectiveness of each in terms of the speed of the publication and subscription of topic , required resources and distribution of load .

The advantage of peer-to-peer (P2P) paradigm relies on two main concepts: cooperation among
users and resource sharing. There are many applications based on peer-to-peer paradigm, but
the most popular one is the file sharing. We can classify the fi
le sharing application into
centralized systems, (having a central server), and decentralized systems. Another classification
would be structured and unstructured systems, based on the way of managing the indexing
information. In this paper, we have implemented a centralized peer-to-peer application for file
sharing. Then we evaluated the performance of the system by means of simulation.
Publish/Subscribe Systems become increasingly important, mainly because they
provide a full decoupling between the publishers and the subscribers, with respect to space,
time, and synchronization. This research presents an overview of publish/subsc
ribe
systems and epidemic algorithms (especially the directed ones), and studies the
performance of directed epidemic algorithms used to ensure the reliability of
publish/subscribe systems. Adopting Scribe system and simulation using OMNET++, the
paper evaluates different directed epidemic algorithms by considering many factors:
targeted range width, number of rounds, number of nodes, and packet loss rate, on each of:
the reliability, overhead, and mean latency.
Application-Level Multicast Networks are easy to deployment, it does not require
any change in the network layer, where data is sent to the network via the built-up
coverage of the tree using a single-contact transmission of the final contract, who
are the
hosts are free can join / leave whenever they want it, or even to leave without telling any
node so. Causing the separation of the children of the leaved node from the tree, and the
request for rejoin, in other words, these nodes will be separated from the overlay tree and
cannot get the data even rejoin. This causes the distortion of the constructed tree, and the
loss of several packets which can significantly impact the user.
One of the key challenges in building a multi-efficiently and effectively overlay
multicast protocol is to provide a robust mechanism to overcome the sudden departure of a
node from the overlay tree without a significant impact on the performance of the
constructed tree. In this research, we propose a new protocol to solve problems presented
previously.
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.
Mobile wireless sensor network (MWSN) is a wireless ad hoc network that consists
of avery large number of tiny sensor nodes communicating with each other in which
sensornodes are either equipped with motors for active mobility or attached to mobile
objectsfor passive mobility. A real-time routing protocol for MWSN is an exciting area of
research
because messages in the network are delivered according to their end-to-end
deadlines
(packet lifetime) while sensor nodes are mobile. This paper proposes an enhanced
realtime
with load distribution (ERTLD) routing protocol for MWSN which is based on our
previousrouting protocol RTLD. ERTLD utilized corona mechanism and optimal
forwardingmetrics to forward the data packet in MWSN. It computes the optimal
forwarding nodebased on RSSI, remaining battery level of sensor nodes and packet
delayover one-hop. ERTLDensures high packet delivery ratio and experiences minimum
end-to-end delay in WSNand MWSN compared to baseline routing protocol. . In this paper
we consider a highly dynamic wireless sensor network system in which the sensor nodes
and the base station(sink) are mobile.ERTLD has been studied and verified and compared
with baseline routing protocols RTLD,MM-SPEED , RTLCthrough Network Simulator-
