Wireless sensor networks are increasingly used in many emerging applications. This type of network is composed of hundreds of low-cost sensor nodes, but with a limited budget batteries, low communication range, limited throughput, reduced computing power, low memory and low storage capacity. Communication protocols are proposed in the literature to deal with technical challenges coming from low intrinsic resources of sensor nodes. In most of these studies, simulations comparing a proposed protocol with other existing protocols are performed to show that the proposed protocol provides overall better performance. However, the environmental specification that made these comparisons is very often neglected or non-existent. In this study we show that it is essential to have the simulation environment very well defined before considering whether a protocol provides better performance than others. To do this we use two duty cycle MAC protocols, the standard IEEE 802.15.4 and SlackMAC (a protocol that we proposed). The aim of the paper is not to make an exhaustive comparison of protocols. We intuitively know that SlackMAC provides a better overall performance than the standard. What we are trying to show is the gap between performances according to simulation conditions. We will mainly focus on the topologies used and the capture effect. The results draw attention to the fact that it is essential to clearly define the simulation environment and also to reconcile the chosen conditions with the results when comparing the performances of two protocols.

“…In asynchronous duty cycle MAC protocols, nodes do not have a common calendar for their activity and sleep periods. This is the case of X-MAC [9], OSX-MAC [10], RI-MAC [11], HKMAC [12], AaaMAC [13] and SlackMAC [14], [15]. In these protocols quantitative results of simulations comparing them with other existing protocols are given.…”

Many protocols for wireless sensor networks are proposed in the literature. In most of this work, comparisons are made with existing protocols to show that the proposed protocol provides better overall performance without precise specifications of the simulation environment. In this paper we show that for a given propagation model, the value of its main parameters retained in the simulation process has very significant effects on the quantitative results. To do this, we use an asynchronous MAC protocol that we proposed which was compared with the reference MAC protocol specified in the standard IEEE 802.15.4 in beacon enabled mode. We use a realistic propagation model like log-Shadowing and we modify the parameters of this model. In this contribution, we also vary the capture threshold. We intuitively known that the asynchronous MAC protocol will ensure a better overall performance than the standard, we will try to show the diversity of results by intensive simulations. To the best of our knowledge, there are existing studies that show the impact of different propagation models on simulation results. However, no studies have shown this impact with such an important level of detail. From this study we estimate that when two communication protocols are compared, it is important to associate the performance curves with the precise and detailed conditions used for the simulation and to assess the global influence. According to this influence, a vigilance can be reported on the accuracy of results.
