چکیده

A wireless mobile ad hoc network (MANET) is a collection of solely independent nodes that communicate with each other by forming a single hop/multi-hop network, and maintain connectivity in a decentralized manner. The important characteristic of the ad hoc network is that the nodes move randomly around the area of deployment making the topology highly dynamic. Because of this configuration and absence of infrastructure, an ad hoc network has been in increasing demand during emergency situations like human-induced disasters, military conflicts, emergency grounds, commercial applications and so on. The reliability of the ad hoc network is the most challenging and interesting issue because of its changing topology. This paper addresses and illustrates the effect of few scenario metrics, viz., network size, transmission range, and network coverage area, on the reliability measures (i.e., 2TRm and ATRm) by modeling MANET as Geometric Random Graph.

Estimating Reliability in Mobile ad-hoc Networks Based on Monte Carlo Simulation (TECHNICAL NOTE)

Each system has its own definition of reliability. Reliability in mobile ad-hoc networks (MANET) could be interpreted as, the probability of reaching a message from a source node to destination, successfully. The variability and volatility of the MANET configuration makes typical reliability methods (e.g. reliability block diagram) inappropriate. It is because, no single structure or configurat...

Secure Routing Protocol: Affection on MANETs Performance

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...

Improving Quality of Service Routing in Mobile Ad Hoc Networks Using OLSR

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...
