体域网峰值传输速率弹性跨层广播
Peak Transmission Rate Resilient Crosslayer Broadcast for Body Area Networks
摘要：
无线体域网（WBAN）开辟了无线传感器网络（WSN）研究的一个跨学科领域，在医疗保健领域具有巨大的影响，传感器用于监测、收集和传输人体的生物参数。提出了WBAN中第一个网络-MAC跨层广播协议。我们的协议，在OMNET++模拟器中进行评估，丰富了现实的人体移动模型和信道模型，从最近的研究生物医学和健康信息学，优于现有的广播策略的覆盖节点的百分比，能源消耗和正确接收的因果顺序的数据包（即数据包被接收的顺序相同，因为它们被发送的汇）。此外，我们调查现有的广播策略和我们的新协议面对各种传输速率和人体流动性的弹性。现有的广播策略无一例外地在传输速率超过11 Kb/s时性能开始急剧下降，而我们的跨层协议性能在传输速率达到190 Kb/s时仍保持良好的性能。
英文摘要：
Wireless Body Area Networks (WBAN) open an interdisciplinary area within Wireless Sensor Networks (WSN) research, with a tremendous impact in healthcare area where sensors are used to monitor, collect and transmit biological parameters of the human body. We propose the rst network-MAC cross-layer broadcast protocol in WBAN. Our protocol, evaluated in the OMNET++ simulator enriched with realistic human body mobility models and channel models issued from the recent research on biomedical and health informatics, outperforms existing at broadcast strategies in terms of percentage of covered nodes, energy consumption and correct reception of causally-ordered packets (i.e. packets are received in the same order as they were sent by the sink). Furthermore, we investigate the resilience of both existing at broadcast strategies and our new protocol face to various transmission rates and human body mobility. Existing at broadcast strategies without exception start to have a drastic drop of performances for transmission rates above 11Kb/s while our cross-layer protocol performances maintains its good performances for transmission rates up to 190Kb/s.
