近年来，无线传感器网络最新颖的应用之一是在生物医学研究领域。生物医学传感器网络是由嵌入人体内部的微小无线传感器节点组成的。此类网络中使用的通信协议必须防止网络中热点的形成，同时有效地路由数据，同时节省能源。本文提出了一种跨层的生物医学传感器网络介质访问控制（MAC）协议和路由协议协同设计。网络和MAC层之间的跨层交互有助于优化体内网络的整体性能。大量的模拟已经完成，以表明，建议的Bioprock协议执行更好地比其他现有的MAC和路由协议，在防止热点的形成，减少节点的能量消耗和防止网络拥塞时，在体内网络中使用。Biocomm的一种变体Biocomm-D已被提出用于延迟敏感的生物医学传感器网络应用。
One of the most novel applications of wireless sensor networks in recent years has been in the field of biomedical research. Biomedical sensor networks are formed by tiny wireless sensor nodes, embedded inside the body. The communication protocol used in such networks must prevent the formation of hotspots in the network and at the same time route data efficiently, while conserving energy. In this paper we propose a cross-layer medium access control (MAC) protocol and routing protocol co-design for biomedical sensor networks. The cross-layer interactions among the network and MAC layers help optimise the overall performance of the in vivo network. Extensive simulations have been done to show that the proposed Biocomm protocol performs much better than the other existing MAC and routing protocols in terms of preventing the formation of hotspots, reducing energy consumption of nodes and preventing network congestion when used in an in vivo network. A variation of Biocomm, Biocomm-D has been proposed for delay-sensitive biomedical sensor network applications.
