A mobile ad-hoc network (MANET) is groundwork less system of movable devices associated by wireless links. Every device in MANET is unrestricted to move arbitrarily on any path and will therefore transform its links to new devices promptly and unpredictably. MANETs can interconnect with each other without the usage of a predefined arrangement or federal administration. In this paper routing pro...

Wireless ad-hoc networking can be employed to build inter-vehicle communication based applications. The associated hostile driving environment and high mobility exposes the routing protocol to a more dynamically changing topology. In this work we investigate and demonstrate the application of linkconnectivity assessment to efficient ad-hoc routing. A framework for enhancements is delineated and...

With the current increase in ad-hoc mobile networks in public domains (e.g. airports, cities, etc.), and the widespread use of IEEE802.11 wireless LAN, there is a growing need to handle and manage fast mobility. Extending the coverage area of ad-hoc networks and taking into account fast mobility in routing protocols could offer a complementary solution to the UMTS for fourth generation (4G) mob...

OLSR (Optimized Link State Routing Protocol) is a routing protocol designed especially for MANETs (Mobile Ad hoc Networks) and is currently the most widely deployed for this type of networks. OLSR uses multipoint relay (MPR: MultiPoint Relay) flooding mechanism to optimize topology control messages broadcasting throughout the network. Each node of the network selects a subset of nodes (MPR) amo...

In this paper we present a plugin for OLSR. This plugin is used for adding an interface for between the olsrd daemon and other applications. Using the plugin, other applications, ranging from network services such as DNS, to broadcast voice traffic can use the broadcast mechanisms from the OLSR protocol. This means that the applications can flood the ad hoc network using the optimized MPR-funct...

It is difficult to build an accurate model to predict the dynamic error of CMM by analyzing error sources. An innovative modeling method based on Variance Analysis and Improved Partial Least-square regression (IPLSR) is proposed to avoid analyzing the interaction of error sources and to overcome the multi-collinearity of Ordinary Least-square regression (OLSR). Among many impact factors the mos...

The aim of this research is to modify OLSR using GA to reduce the end to end delay and to improve the network throughput. Simulation was carried out for multimedia traffic and video streamed network traffic using OPNET Simulator. Routing is a primary MANET function where each node forms routes between nodes not directly in each others range for communication. Major challenges in MANET are routi...

The Optimized Link State Routing Protocol is developed for Mobile Ad Hoc Network. It operates as a table driven, proactive protocol. The core of the OLSR protocol is the selection of Multipoint Relays (MPRs), used as a flooding mechanism for distributing control traffic messages in the network, and reducing the redundancy in the flooding process. A node in an OLSR network selects its MPR set so...
