摘要： 针对无线传感器网络中节点能源和带宽受限等问题，提出一种基于位置的自适应实时路由协议。该协议自动调整数据包在不同时刻的实际传输速率，选择较匹配的传输路径，满足了不同应用情况下不同层次的网络实时性需求，提高了网络节点的能量有效性。OMNET++软件平台上的仿真实验结果证明，该协议提高了网络的实时性、数据包有效到达率，并延长了网络的寿命。

Abstract: A location-based Adaptive Real-Time Routing Protocol(ARTRP) is proposed on the ground that each node in wireless sensor network possesses some problems, such as energy conserving, limited bandwidth, and so on. In order to meet different levels real-time requirement for different applications and improve the energy efficiency, this protocol automatically adjusts data packets transmission rate at different times, selects the optimal flow paths. On the OMNET++ software platform, simulation results show that it increases the real-time characteristic, data packet arrival rate and network lifetime.
