A mobile ad hoc network is a group of wireless mobile nodes with no infrastructure, in which individual mobile nodes are able to self organize and self configure in order to communicate within a direct wireless transmission range. However, the vulnerable nature of the mobile ad hoc networks (MANETs) makes them very prone to an adversary's malicious attacks such as dropping data or sending fake data...
Scaling to large networks and dealing with high mobility define the major challenges in designing routing protocols for Mobile Ad hoc NETworks (MANETs). These protocols must be efficient in order to ensure quality of service (QoS) support and energy efficiency. In this paper, we investigate the effect of density and mobility on routing operation on the basis of a high level of QoS jointly accounting...
Mobile Ad-hoc Networks are highly reconfigurable networks of mobile nodes which communicate by wireless links. The main issues in MANETs include the mobility of the network nodes, energy limitations and bandwidth. Thus, routing protocols should explicitly consider network changes into the algorithm design. In order to support service requirements of multimedia and real-time applications, the routing...
Consuming less energy to evenly distribute the traffic load defines a major task for efficient routing protocols in Mobile Ad hoc Networks (MANets). Indeed, this process can avoid congestion, increases the network lifetime and maintains consequently green communications. In order to evaluate this capability, we introduce in this paper a new performance metric “Energy Efficiency of Load Balancing metric”...
Due to high mobility of nodes, the major challenge of mobile ad hoc networks (MANETs) is the frequent link breakages which lead to numerous path failures and route discoveries. This paper introduces a novel signal strength based algorithm for RREQs forwarding (SAODV) to better exploit the neighbor coverage knowledge and hence reduce routing overhead in MANETs. The simulation results confirm the efficiency...
Mobile Ad hoc networks are characterized by a frequently changing in the network topology and the need of an efficient dynamic routing protocol. In this work, we have compared the performance of five ad hoc routing protocols against three different mobility models using NS-2 simulations, the simulated protocols are: AODV, OLSR, DSR, DSDV and ZRP. Furthermore, we examined the impact of traffic load,...
In this paper we propose a management approach of routing based on one of the largest existing reactive routing protocols which is AODV, and able to minimize routing messages (overhead) in contexts with strong constraints. This approach takes into account a metric based on energy consumption during the route discovery, in order to increase the lifetime of the network, and also allows such applications...
