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...

Mobile ad hoc networks (MANET) are constructed by mobile nodes without access point. Since MANET has certain constraints, including power shortages, an unstable wireless environment and node mobility, more power-efficient and reliable routing protocols are needed. The OLSR protocol is an optimization of the classical link state algorithm. OLSR introduces an interesting concept, the multipoint r...

Ad hoc network is a collection of wireless mobile nodes dynamically forming a temporary network without the aid of any established infrastructure or centralized administration. Routing protocols in mobile ad hoc network helps node to send and receive packets. In this paper our focus is to study Reactive (AODV), Pro active (OLSR), and Hybrid (ZRP) protocols based on random waypoint mobility mode...
