The beacon order and Superframe order parameter values, as defined by the IEEE 802.15.4 standard specification, constrain the number of data packets that can be transmitted through a network in a given period by inferring the length of the network’s active and inactive periods. Choosing a specific value of either parameter can have significant impact on various quality of service measurements. This study offers a synthesis of the execution result of a large number of networking simulations, carried out using the NS2 tool. The simulations describe networking situations of varying beacon order and Superframe order values, as well as the number of full-function devices and reduced-function devices in randomized topologies. The performance of the networks in each simulation is assessed through measuring standard quality of service measurements, such as the package delivery ratio, throughput, average delay, and consumed energy. The analysis shows that the characteristic curves describing the progression of the quality of service measurements do not vary significantly with respect of the number of devices that comprise a network within the range of simulated values.
