Abstract
Though, Wireless Sensor Networks have many successful applications in military, smart building, habitat monitoring, etc. it just begun to show its superiority in the medical domain in recent years. Deployment of WSNs in medical domain exert many more stringent requirements on the capability of sensing and in-networking processing, due to the nature of high accessibility and the privacy sensitive requirement of medical environment, the application of WSN such as Wireless Personal Area Network (WPAN) must be carefully examined before practical use. This paper considers the performance of WPANs under different scenarios, which are the WSNs deployed in the medical and healthcare domains. It focuses on the behaviour of sensor nodes while accessing the shared channels during communicating each other. The channel access mechanism described as the slotted CSMA with collision avoidance (CA) in the network compliant the IEEE 802.15.4 standard are often investigated by the Markov chain modelling technique used in many complex systems. The performance matrices provide many insights to the technical designers and service users of WPAN systems.
尽管无线传感器网络在军事、智能建筑、人居监测等领域已经有了很多成功的应用,但近年来在医疗领域才开始显示出它的优势。无线传感器网络在医疗领域的部署对传感能力和网内处理能力提出了更为严格的要求,由于医疗环境的高可访问性和隐私敏感性要求,无线个人区域网络(Wireless Personal Area Network, WPAN)等无线传感器网络的应用在实际使用前必须经过仔细的审查。本文研究了部署在医疗卫生领域的无线传感器网络在不同场景下的性能。它关注传感器节点在相互通信期间访问共享通道时的行为。在符合IEEE 802.15.4标准的网络中,带避碰(CA)的开槽CSMA通道访问机制常被用于许多复杂系统的马尔可夫链建模技术的研究。性能矩阵为WPAN系统的技术设计人员和服务用户提供了许多见解。
