Routing in Vehicular Ad Hoc Networks (VANETs) is still a challenging issue due to intrinsic characteristics — especially limited resources and high mobility- of these mobile networks. The AODV routing protocol is one of the applied protocols in such networks since it can adapts to network continuous topology changes. Nevertheless, its performance may suffer from high frequency VANET dynamics as they...
This paper investigates the congestion control issue in the Internet, especially in wireless environments, and proposes a new congestion control scheme, called Proportional and Derivative (PRDR). Based on the Active Queue Management (AQM) principle, the designed PRDR controller embedded to the router monitors the level of network congestion through the occupancy of the buffer which is maintained within...
