This letter presents a Flow-Level Extension to OMNeT++ (FLEO) that allows a discrete event simulator to operate on flows of traffic, and so simulate larger networks for longer periods of time for a given set of computation and memory resources compared with packet-based simulation. FLEO simulations of link utilization are accurate to within 0.2% of a packet-based simulation, yet run 30 to 90 times...
In this paper, we propose an adaptive pacing scheme at the link layer for IEEE 802.11 based multihop wireless networks. Our objective is to improve the performance of higher layer protocols without any modifications to them. Our adaptive pacing scheme estimates the four-hop transmission delay in the network path without incurring any additional overheads, and accordingly paces the packets to reduce...
