تتميز الشبكات اللاسلكية MANETs بسهولة بنائها وسهولة النشر والتجهيز والكلفة المنخفضة، ولذا فهي تنتشر كثيراً في المناطق التي يعد فيها إنشاء شبكة ذات بنية تحتية أمرا مكلفا، ولذلك ينظر على أنها البديل للشبكات المحلية ذات البنى التحتية في تلك المناطق لميزاتها وخصائصها. ومن هنا يعتبر تحقيق الأمن في هذه الشبكات من المتطلبات الرئيسية لاستمرارية عمل الشبكة بشكل صحيح. يعد التسيير Routing من أهم القضايا في شبكات ال MANETs، هناك العديد من الهجمات المعروفة والمشاكل الأمنية التي تتعرض لها عملية التسيير ولذلك لا بدّ من تامين بروتوكول تسيير آمن في هذه الشبكات. نعرض في هذا البحث نموذجاً لتوفير الحماية للبروتوكول AODV (ad-hoc On Demand Distance Vector) أحد بروتوكولات التسيير في هذه الشبكات. يحقق البروتوكول المذكور تأمين طريق آمن بين العقد بالإضافة إلى تحقيق الاستيقان المتبادل Mutual Authentication، وحماية رسائل التسيير من التعديل وأخيراً إمكانية الاتفاق على توليد وتبادل مفتاح حماية المعطيات المرسلة بعد اكتشاف الطريقة (مفتاح الجلسة session key), وذلك جميعاً في مرحلة واحدة. نضمن بذلك توفيراً في عرض الحزمة وتوفيراً في استهلاك موارد العقد ومنع تكرار بعض خوارزميات الاستيقان.
Mobile ad-hoc Networking MANETS is a promising concept to provide flexible, adaptive, and reconfigurable architecture, cost effective solution.In the mobile ad hoc network security is the basic concern for network functions work properly.Routing is the corner stone in Mobile ad-hoc Networks, A lot of known vulnerabilities and security threats can be exploited to attack routing messages, so it is important to provide secure routing protocol for MANETs.In this paper, we present a secure extension for ad-hoc On Demand Distance Vector Protocol (AODV). The default routing protocol for MANETs. The proposed protocol ensures that discovery of the route between the nodes is functioning properly and securely, achieving mutual authentication between nodes, routing message integrity, generating a security key of data sent and exchanges it securely to ensure confidentiality and all of these are in one stage. By this we save in wireless band, resource consumption, preventing duplicate of authentication algorithms.

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.
Wireless Sensor Networks (WSNs) are deployed in adversarial environments and
used for critical applications such as battle field surveillance and medical monitoring, then
security weaknesses become a big concern. The severe resource constraints of
WSNs give
rise to the need for resource bound security solutions.
The Implicit Geographic Forwarding Protocol (IGF) is considered stateless, which
means that it does not contain any routing tables and does not depend on the knowledge of
the network topology, or on the presence or absence of the node in WSN. This protocol is
developed to provide a range of mechanisms that increase security in IGF. Thus it keeps
the dynamic connectivity features and provides effective defenses against potential attacks.
These mechanisms supported the security against several attacks as Black hole, Sybil and
Retransmission attacks, but the problem was the inability of mechanisms to deal with
physical attack.
This research deals with a detailed study of the SIGF-2 protocol and proposes an
improvement for it, in which we use the concept of deployment knowledge from random
key pool algorithm of keys management to defend against physical attack . The evaluation
of simulation results, with different parameters, proved that our proposal had improved the
studied protocol.
A Vehicular Ad-hoc Network (VANET) is a collection of nodes forming a
wireless network, but the nodes of this network are vehicles with special equipment that
enable them to communicate with each other. VANET protocols have to face high
challenges
due to dynamically changing topologies, link breakage and low vehicular
density. A suitable and effective routing protocol helps to ensure that messages are reached
to their destinations and achieve the desired aim of the application.
In this research, we present an analysis of the performance of two major routing
protocols used in these networks, which are AODV (Ad hoc On-Demand Distance Vector)
and GPSR (Greedy Perimeter Stateless Routing). This analysis is based on various
parameters such as end-to-end delay and average dropped packets, in order to find the best
protocol which can be used in the network with low density at the junctions. To achieve
this purpose, we used a simulator OPNET_17.5. Depending on the simulation results, we
have obtained and the analysis and comparison of two protocols at different low density
contract. We found that GPSR protocol has better performance end-to-end delay and
average dropped packets are used as the performance metrics, and is better for VANET
under the low vehicular density simulation scenario at junctions.
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-

In this paper, we use NCTUns 6.0
to simulate this kind of networks ,because it is difficult to do that is the
real world .In this paper, two routing protocols (AODV, ADV) are
studied within many scenarios to achieve their performances and
reliabi
lity using many metrics.
We conclude that ADV routing protocol adapts quickly when the
complexity of network and mobility of nodes increase. This is achieved
by varying the size and frequency of routing updates.
