Description: Mobile Ad hoc networking is a challenging task due to the lack of resources in the network as well as the frequent changes in network topology. Although lots of research has been done on supporting Quality of Service(QoS) in the Internet and other networks, but they are not suitable for mobile Ad hoc networks and still QoS support for such networks remains an open problem. In our Project, a new scheme has been proposed for achieving QoS in terms of packet delivery, multiple connections, better power management and stable routes. It offers quick adaptation to distributed processing, dynamic linking, low processing overhead and loop freedom at all times. The proposed scheme Stable Backbone node routing protocol (SBNRP) has been incorporated using Adhoc On Demand Vector (AODV) protocol which provides the routing stability.-Mobile Ad hoc networking is a challenging task due to the lack of resources in the network as well as the frequent changes in network topology.

Description: Mobile Ad-Hoc network is a collection of mobile nodes in communication without using infrastructure. De-spite the importance of type of the exchanged data between the knots on the QoS of the MANETs, the mul-tiservice data were not treated by the larger number of previous researches. In this paper we propose an adaptive method which gives the best performances in terms of delay and throughput. We have studied the impact, respectively, of mobility models and the density of nodes on the performances (End-to-End Delay, Throughput and Packet Delivery Ratio) of routing protocol (On-Demand Distance Vector) AODV by using in the first a multiservice VBR (MPEG-4) and secondly the Constant Bit Rate (CBR) traffic. Finally we compare the performance on both cases. Experimentally, we considered the three mobility models as follows Random Waypoint, Random Direction and Mobgen Steady-State. The experimental results illustrate that the behavior of AODV change according to the model and the used traffics. Platform: |

Description: Producing the quality of service in wireless network is a complex subject because of constraints related to the ad hoc mode as limited bandwidth, sharing medium...etc. The traditional routing based on hop count metric doesn’t take in its consideration
the quality of the wireless link which causes the rate reduction in the network. In an effort to improve the performance of Mobile Ad hoc Network (MANET), cross-layer technique is implemented. It aimed to
resolve QOS problems in manet and permit to share information about network status between different layers. Platform: |
