Wearable sensing technologies such as Wireless Body Area Network (WBAN) for hazardous environments moni- toring generate heterogeneous types of traffic with diverse quality of service requirements related to delay, reliability, priority awareness and throughput, for instance. In addition, several WBANs might need to collaborate together by relaying each other's packets, as generated by constraining...
Research in the wireless sensor networks field has been plagued by difficulties in realistic simulations. These difficulties are often the result of non-realistic assumptions which need to be removed from the mathematical models. Especially, radio propagation models are often simplified and do not take into consideration irregularities such as fading, shadowing, and temporal non-stationarity. In this...
IEEE 802.16e amendments for the mesh mode do not specify particular QoS mechanisms. However, each Mesh Subscriber Station (MSS) transmits its own traffic and forwards the traffic of its children while each traffic flow has its particular QoS constraints. As all forwarded traffics use the same link, one MSS may experience starvation or act selfishly. Besides, the MSS's mobility adds important complexity...
