Mobile Ad-Hoc network is a collection of mobile nodes in communication without using any fixed infrastructure. As the multiservice traffic compressors used today's grows, we need to verify if the available protocols support their applications. Therefore, in this paper we have studied the impact of multiservice traffic (MPEG-4, H.264) on the performances of Optimized Link State Protocol (OLSR) p...

The OLSR protocol, as specified in RFC 3626 [1], a proactive, table-driven routing protocol, is a distributed algorithm that relies on all participating nodes obeying to a set of rules. Those rules could be broken easily by some malicious nodes in order to gain some advantage in the network or simply disrupt its proper operation. In this paper, we present a method to detect packet loss on links...

A multiple-metric routing using the proactive Optimized Link State Routing (OLSR) protocol to improve quality of service is proposed. It is known that multiple-metric routing is an NP-complete problem, but the Analytic Hierarchy Process (AHP) and Pruning techniques are used to perform such routing, providing the best available routes based on the considered metrics. The performance of the propo...

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...

The Optimized Link State Routing (OLSR) protocol is a proactive Mobile Ad hoc Network (MANET) routing protocol. OLSR (v1 [1] or v2 [2]) were not designed with integrated security measures. Research provides inputs on how to secure the OLSR protocol against attacks from outside intruders. To address the protocol vulnerabilities, authentication and encryption techniques have been proposed. We wil...

Reliable communication is the backbone of advanced metering infrastructure (AMI). Within the AMI, the neighbourhood area network (NAN) transports a multitude of traffic, each with unique requirements. In order to deliver an acceptable level of reliability and latency, the underlying network, such as the wireless mesh network (WMN), must provide or guarantee the quality-of-service (QoS) level re...

Multipoint relays were introduced to optimize flooding in ad hoc networks. They are also used to determine a sub-topology containing shortest paths in the OLSR routing protocol. We show that a generalized version of multipoint relays can be used to construct a sub-topology preserving bi-connectivity and more generally k-connectivity. Moreover, we show that the multipoint relay structure is intr...

Most networks strive to provide good security and an acceptable level of performance. Quality service (QoS) plays important role in the performance a network. Mobile ad hoc (MANETs) are decentralized self-configuring type wireless MANETs generally challenging provision QoS becomes huge challenge. Many researchers literature have proposed parallel mechanisms that investigate either or QoS. This ...

Unmanned aerial vehicles (UAVs) are widely used in our modern society and their development is rapidly accelerating. Flying Ad Hoc Networks (FANETs) have opened a new window of opportunity to create value-added services. However, the characteristics that make FANETs unique, such as node mobility, distance, energy constraints, etc., imply several guidelines need be considered for successful depl...
