In this proposition, we present a link management technique for pro-active routing protocols for ad-hoc networks. This new mechanism is based on signal strength hence cross layer approach is used. The hysteresis mechanism provided by OLSR is improved upon by using signal strength in combination with the hello loss based hysteresis. The signal power is used to determine if the link-quality is im...

Nowadays, with the development of networked technologies and the great expansion of video games industry, almost all video games propose a multi-player mode. Development of portables consoles which integrate 802.11 technology offers to people the opportunity to play anywhere, at any time and with anybody. However, wireless networked conditions are not always optimal and directly impact the qual...

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...
