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 recent years, Vehicular Ad-hoc Networks (VANETs) have emerged as a unique type of MANETs. VANETs are an important component of the Intelligent Transportation Systems (ITS).

A set of wireless mobile terminals, which cooperate by forwarding packets to each other defines a Mobile Ad hoc Network (MANET). MANETs are attractive for their potential use in several fields such as collaborative computing and smart environments. Considering the limited bandwidth capabilities of the wireless links, communication of MANET nodes needs to be investigated. In this paper, we analyze...
Recently, Mobile Ad-hoc Networks (MANETs) have an increased interest in applications for covering rural areas due to the possibility of usage of low-cost and high-performance mobile terminals, without having to depend on the network infrastructure.

By the rapid adoption of information terminals such as tablets and smart phones, people having multiple wireless communication terminals are expected to increase the access and traffic amount. In public facilities, hot spots, and university campuses, the coverage area of the wireless Access Points (APs) is limited because of high cost. Therefore, it is difficult to provide stable network connectivity...
