Routing in mobile ad hoc networks (MANETs) is central to their proper functioning. Mobility in such networks makes the routing a real challenging task. Routes validity plays a central leveraging mission to enhance network performances. Forwarding through incorrect routes not only results in traffic wandering inside the network without ever being able to be delivered to their ultimate destinations...
Routing in Mobile Ad hoc Networks (MANETs) is central to their proper functioning. Mobility in such networks makes the routing a real challenging task. Although a host of studies has been reported in the literature evaluating the performance of proposed routing algorithms, a deeper insight reveals some residual malfunctioning. On the other hand, routes validity plays a central leveraging mission to...
Vehicular ad hoc networks (VANETs) allow communications over sequences of vehicles with radio devices. On such a network, there are many possible applications such as traffic jam warning, collision warning, parking lot reservations, camera picture feed etc. There have been quite a few results in the area seeking for a fast and reliable communication protocol due to their potential. VANETs, however,...
Delay Tolerant Networks (DTNs), in which contacts between nodes come and go over time, is a promising approach to model communications in mobile ad-hoc networks, where scenarios of network partitioning and node disconnections are likely to happen. One of the most important challenges in such networks is how to route information and schedule transmissions, coping with the continuously changing network...
The goal of this work is to design a new adaptive routing technique for ad hoc wireless networks. This paper proposed the basic deign of the algorithm that works based on the principle of ant colony optimization (ACO). This is a probabilistic adaptive technique that changes its routes with the change of network topology over the period of time by learning its environment. It identifies appropriate...
The next generation communication systems will provide high quality multimedia services in a flexible and efficient manner. As an extension of next generation networks, Mobile Ad Hoc Networks (MANETs) have attracted significant attention amongst researchers. Nodes in a MANET have limited battery power. Hence, ad hoc routing protocols ought to be energy conservative to support real-time multimedia...
This paper examines the performance of reactive ad hoc wireless protocols namely AODV and DSR under different network densities. The relation between connectivity and density is identified in this research. Therefore node density is vital in determining the performance of the network. The probability for a dense network to achieve connection is significantly higher than its sparse counterpart. But...
