摘　　要：无线传感器网络是资源受限的网络,网络中节点较简单且差异小,在许多应用背景中对实时性要求较高。而传统的分层网络体系开销较大且灵活性不高,跨层技术的产生可以弥补这些不足。论文分别从实时性、收集信息需要这两方面提出新的基于跨层技术的网络设计方案,以满足不同应用的需求。Wireless sensor networks are commonly resource limited with simple same nodes. They are always used in some special background which needs nodes to act in real time. However, traditional five-layer networks architecture consumes much resource and are short of flexibility. Cross-layer design can make up the lack which we can see in detail from the text. We put forward two kinds of design based on different aspect including time saving and information collecting.
