A typical Body Area Network (BAN) involves multiple on- body sensors exchanging information with a central gateway, forming a star topology network. The characterization of sensor-to-gateway wireless links is clearly important in sim- ulation, as indicated by substantial research efforts to col- lect experimental traces and model them. Sensor-to-sensor links on the other hand, have received less attention, due to the fact that there is no immediate communication between sensors and, at the same time, it is expensive to collect ex- perimental traces for all node combinations. Nevertheless, these links affect communication when contention-based ac- cess protocols are considered, therefore creating a model- ing need. In this paper we investigate models for sensor- to-sensor links, in simulation scenarios which employ two established communication standards, namely 802.15.4 and 802.15.6. These standards rely on a mix of CSMA and TDMA to enable wireless communication between sensors and the gateway. We show that sensor-to-sensor links are indeed important in simulation, and investigate the effect of different modeling approaches on application layer results and computational overhead. Moreover, we show the corre- spondence between two different modeling approaches and suggest the simpler one is sufficient to carry out simulation studies over a wide range of scenarios.
