Adaptive Packet Aggregation for Header Compression in Vehicular Wireless Networks

Generally, header compression can be used with packet aggregation to make more efficient use of wireless bandwidth. Header compression reduces the waste of the header size, while packet aggregation reduces the number of packets. Unfortunately, packet aggregation might increase the end-to-end delay in multi-hop vehicular environment. The goal of this paper focuses on header compression and packet aggregation in vehicular networks. We propose an adaptive packet aggregation mechanism for header compression. The proposed mechanism will make a tradeoff between delay time and compression efficiency. Finally, we used the ns-2 simulator to perform the simulation experiments. Simulation results showed that our proposed mechanism performs better than the existing schemes which did not aggregate packets adaptively for data transmission in terms of the average end to end delay and packet arrival rate.
