User applications on the internet cannot beget bandwidth guarantees from the network. Therefore, it is important to measure the available capacity bandwidth as well as link capacities so that the user applications may adopt these parameters to determine the applicability of the service. For measurement of the available capacity bandwidth between devices in a wireless network, active capacity measurement methods are used. Data packets inform of packet probes are inferred into the network from the sending device. These data packets are stamped with time at the end node. The available bandwidth is analyzed from the separation with the time stamped packets as the input. It is expected that measurement of bandwidth capacity in a low intrusive network, sender based probe would be equal to the theoretical capacities. The theoretical estimated capacities are done at the last hop node in a given network setup. In this dissertation work, bandwidth capacity measurement is done from the sender-node. The results obtained indicate that the simulated network results in bandwidth capacity that is relatively indicative of wireless capacities that are known in theory as discussed in the research work. However, in real networks, these may not be realized as the practical networks will have cross traffic as a result of other devices in the network that are communicating and sending packets as well. These packets will cause an increase in the round trip time.
