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(More)
Multi-Protocol Label Switching is useful in managing multimedia traffic when some links are too congested; MPLS Traffic Engineering is a growing implementation in today's service provider networks. In This paper we propose an improvement of MPLS-TE called EMPLS-TE, it is based on a modification of operation of Forwarding Equivalence Class (FEC) in order to(More)
Recently, multimedia becomes increasingly popular for the users of ad hoc networks. To support multimedia and real-time application the study of QoS issues in MANETs is essential. MANETs can provide efficiently multimedia users with the required mobility. Development in multimedia and ad hoc networking has spurred rapidly growing research interested in(More)
IPv6 is a next-generation Internet layer protocol designed by the IETF (Internet Engineering Task Force) to solve the problem of IP address depletion under the current Internet layer protocol. It has been developed to replace the current Internet Protocol version 4 (IPv4). Various operating systems support IPv6 protocol stacks and network infrastructures(More)
The QoS routing generates a significant number of control messages (overhead), which are necessary for the discovery and maintenance of routes. Indeed, the nodes must establish a mechanism to store and update the link-state in a mobile environment. This mobility in ad-hoc environment makes maintaining the linkstate very difficult and costly. In addition to(More)
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(More)
Wireless Sensor Networks (WSNs) are an active research field which attracted many researches. WSNs are an advanced technology applied in a various fields. The minimization of the node energy consumption represents a very serious problem. Long communication distances between nodes in a Wireless Sensor network can greatly drain the energy of nodes and reduce(More)
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(More)
