In this paper, we investigate the performance of AODV routing protocol in a Manhattan grid scenario when sending triple flow. We considered two different scenarios with three TCP flows (TCP1xTCP2xTCP3) and one UDP flow and two TCP flows (UDPxTCP1xTCP2) and data rates of 0.1 Mbps and 1 Mbps. For the simulations, we used SUMO to generate the vehicle movement and NS3 to analyze the network performance...
In this paper, we investigate the performance of OLSR and AODV protocols in a Manhattan grid scenario when sending triple TCP flow over FTP. We considered data rates of 0.1 Mbps and 1 Mbps. For the simulations, we used SUMO and NS3. We considered IEEE 802.11p standard and TwoRayGroundPropagationLossModel. We use through-put and cwnd as evaluation metrics. The simulation results show that for small...

The Wireless Sensor Networks (WSNs) have a wide range of applications such as target detection and tracking, environmental monitoring, and tactical systems. However, lower sensing ranges result in dense networks, which brings the necessity to achieve an efficient medium access protocol subject to power constraints. Various MAC protocols with different objectives were proposed for wireless sensor networks...
MANETs are temporary networks, that spend less time to be deployed and less resources to keep up and running. MANETs can be implemented in disaster recovery sites, university campuses, military campaigns and so on. MANET nodes cooperate in an autonomous way by forwarding packets to each-other. Considering mobility of the terminals, the routes change dynamically so routing algorithms are very important...
