A Mobile Ad hoc Network (MANET) is made up of mobile nodes that communicate through wireless connections, without any existing infrastructure or central administrator. Topology of the network is not fixed. Hence, routing in dynamic network is a new challenge. Nature-inspired algorithms (swarm intelligence) such as Ant Colony Optimization algorithms have shown to be a good method for expanding routing...
Topology control aims to provide more spatial reuse and power conservation while keeping network's connectivity. However just a few number of efforts focused on the issue of topology control with mobility. Some of topology control algorithms (e.g. CEC) try to provide more energy conservation by sleeping the redundant nodes. This paper presents a sleep-based topology control algorithm, which is in...
This paper presents a new protocol for the formation and maintenance of a backbone from the nodes of an ad hoc network where all the nodes are mobile. The new protocol is defined and its performance evaluated with respect to metrics such as its size, that favors scalability, its connectivity in time, which allows protocols to run efficiently, robustness and route length. Via ns2-based simulation experiments...
Nowadays, inter-domain routing for MANETs draws increasing attention because of military and vehicular applications. The challenges in wireless, mobile inter-domain routing include dynamic network topology, intermittent connectivity, and routing protocol heterogeneity. The existing Border Gateway Protocol (BGP) is the de facto inter-domain routing protocol for the Internet. But BGP is not applicable...
This paper proposes a dynamic energy efficient clustering algorithm for mobile ad hoc networks (MANETs). The proposed algorithm elects first the nodes that have a higher energy and less mobility as cluster-heads, then periodically monitors the cluster-heads' energy and locally alters the network topology or the clusters to increase the network lifetime by reducing the energy consumption of the suffering...
The support of ad-hoc networks as extension of infrastructure operator networks is increasing its strength in next generation networks, due to the increasing requirement for ubiquitous access of the users. This paper describes the ad-hoc network integration mobility architecture being developed inside the IST project Daidalos II. The main purpose of this architecture is to seamlessly support the movement...
