Unicast in data networks is the exchange of IP packets between a single sender and a single receiver over a network using Transmission Control Protocol (TCP). The effect of the mobility rate on the bandwidth is largely pronounced in such a network which generally reduces the overall performance of the network. In this paper, an experimental procedure was implemented to actually determine the effect of mobility rate on the bandwidth and how to minimize the effect to the minimum attainable for improved performance of Mobile Unicast Data Network. We adopted two test scenarios involving two hosts connected to each other through (801.11g) wireless adapter; we run iperf on both laptops and used it to configure one as the server and the other as the client. In the first section, the mobility rate of the client is varied while the server is given a fixed position. However, in the second section, we kept all the configurations the same as in the first except that the server is now the mobile host and the client is the fixed host. We sent traffic from the client to the server for 10secs at 2secs interval and used iperf to measure the bandwidth at each designated mobility rate and observed how the bandwidth varies successively when moving either the server or client in each section of the experiment. The measurements indicated degradation in the performance of the network by reducing the bandwidth as the mobility rate increased when either of the hosts is in motion. We also observed that the effect was more adverse on the bandwidth when the client was in motion as there is a wider variation in the measured bandwidth. However, we also observed that the measured bandwidth became narrower when the server is in motion. Therefore, to minimize the effect of the mobility rate on the bandwidth of the network, we recommend that the server should be the mobile host while the client should be the stationary host.

In this paper an experimental procedure was implemented to actually determine the effect of mobility rate and how to minimize the effect on the performance of Mobile Unicast Data Network. We adopted two tests scenarios; in the first, the bandwidth of a network (Net1) where the client is enabled to move at a given mobility rate while keeping the server stationary were measured at designated mobility rates, on the other hand, in the second test scenario we took measurement of the bandwidth of the network (Net2) where the server is enabled to move at corresponding mobility rate while keeping the client stationary. We observed that as the mobility rate increases, the bandwidth of both networks decreased resulting to general performance degradation. Moreover, the impact was more pronounced when the client was put to motion than when the server was in motion.
