中文摘要：
生物无线传感器网络在通信时，传感器节点会对其邻近的人体组织产生有害的电磁辐射，并由此引出了温度问题。在生物无线传感器网络中，如只考虑节点的能量问题，则可能致使某部分组织因局部温度过高而受到损伤，因此，传统的传感器网络路由算法并不能完全适用。本文基于以上问题提出一种新的簇头转换算法，综合考虑节点的能量、温度等问题，为各节点设定优先级，选择优先级最高的节点作簇头节点。从而使传感器节点邻近组织的温度得到控制，并且各节点的剩余能量也较为均匀。与传统的算法相比，降低了网络节点对人体的损伤，同时延迟了第一个死亡节点的出现。
英文摘要：
In wireless bio-sensor network, bio-sensor nodes can be planted into human body to supervise and diagnose people＇s health. However, during the communication, the bio-sensor nodes may cause harmful electromagnetism radiation to human tissues, and thus educe the issue of temperature. If just consideration of remain energy of nodes, it will hurt surrounding tissues by increasing the temperature in these part. In this paper, a novel arithmetic of leader conversion was brought forward. The energy of nodes and the temperature of the surrounding tissues were considered synthetically. Priority was set for bio-sensor nodes, and the node with highest priority was chosen as the leader. The temperature of the tissue surrounding bio-sensor nodes had been controlled in this method, and there was very little discrepancy between remain energy of each node. When compared with conventional arithmetic, leader priority conversion arithmetic reduced the damage of the tissue due to thermal effect caused by network nodes, and deferred the appearance of the first dead node.
