As more and more real Wireless Sensor Network’s (WSN) applications are tested and deployed over the last decade, the research community of WSN realizes that several issues need to be revisited from practical angles, such as reliability and availability. Basically, wireless sensor networks suffer from resource limitations, high failure rates and faults caused by the defective nature of wireless ...

Wireless Mesh Networks (WMNs) can be the key technology for the future of wireless networks. However, WMNs implementation still has many issues to be resolved especially on finding the best path to forward information. According to many researches, one of the most important component in WMNs is the routing protocol and how to make it efficient in performing the requirements of WMNs. Directional...

Network control system (NCS) has higher requirements on QoS index of the network, but MANET can hardly meet the demands of control systems because of its own characteristics. The paper improves AODV and proposes AODV routing protocol QAODV with certain QoS security in combination with NCS and MANET, and expounds routing detection, routing register and routing maintenance. Simulation results sho...

Ad Hoc network is a network without physical structure and is established with mobile nodes using wireless connections. Ad Hoc network is highly flexible and supports dynamic network topology. Thus, the efficiency of the routing protocol will affect the overall network performance. Mobile ad hoc networks carriage several kinds of security problems, initiated by their open systems and nature of ...

in mobile ad hoc networks, the absence ofinfrastructure and the consequent absence of authorizationfacilities impede the usual practice of establishing a practicalcriterion to distinguishing nodes as trusted and distrusted.since all nodes in the manets would be used as router inmulti-hop applications, secure routing protocols have vital rulein the security of the network. so evaluating the perf...

There are a number of implementations of the Ad-hoc On-demand Distance Vector (AODV) routing protocol available for the Linux platform, but not for any other platform. Development of ad-hoc routing protocols has been slow because current operating systems do not provide adequate direct system-services for their implementation. This dissertation presents a design, implementation, and evaluation ...

AODV is a reactive MANET routing protocol that does not support security of routing messages. SAODV is an extension of the AODV routing protocol that is designed to fulfil security features of the routing messages. In this paper, we study the performance of both AODV and SAODV routing protocols under the presence of blackhole, grayhole, selfish and flooding attacks. We conclude that the perform...

Mobile ad hoc network (MANET) is characterized as a dynamic, multi-hop wireless self-organized distributed ad hoc network. Because of node mobility and power limitation, the network topology changes frequently which leads to path breakage. Hence a dynamic routing protocol is required for ad hoc networks to function properly. Reactive on -demand routing protocols becomes very popular because it ...
