近年来，无线传感器网络在多种类型的监控应用中得到了广泛的应用。在通常情况下，用于监控应用的传感器节点都使用同构的介质访问控制。对于像丛林火灾监测这样的应用，当发生野火时，一些传感器节点具有关键信息，需要立即传输到基站。由于整个传感器节点都在同时传输传感器分组，在这种情况下，空中通道会非常拥塞，会产生巨大的分组丢失。因此，本文对CSMA/CA优先方案进行了评估。
Wireless sensor network has been widely used in many types of monitoring application in these recent years. In usual case, the sensor nodes for monitoring application are using homogenous medium access control. For an application such as jungle fire monitoring, there are some sensor nodes which have critical information that needs to be transmitted to base station immediately when a wild fire breaks out. Due to the entire sensor nodes are transmitting the sensor packets at the same time, the air channel will be very congested and there will be huge packet losses in this situation. Therefore, in this paper, evaluation of CSMA/CA priority scheme has been conducted.
