摘要:

无线传感器网络在军事和民用领域均具有广阔的应用前景,但由于传感器节点资源的限制,网络能否满足在实际应用中的QoS要求是一个重要问题。本文对无线传感器网络的主要QoS指标进行了介绍,并分别从能量效率、丢包率、吞吐量和传输时延等主要QoS指标对三种典型拓扑结构的无线传感器网络进行了分析;实现了基于NS2的无线传感器网络通用仿真平台,借助此平台对典型拓扑结构的传感器网络主要QoS指标进行了仿真验证和分析,得到了不同拓扑结构对无线传感器网络QoS指标的影响程度。

Abstract:

Wireless sensor networks (WSN) can be broadly used in military and civilian areas. Due to the limitations of inherent characteristics of sensor nodes and lack of high level protocols and abstract algorithms suitable for the speed of processing large networks, it is crucial for the WSN to satisfy the demand of the user's quality of service (QoS), and the research of QoS in real applications has become a hot issue. The paper firstly introduces the main QoS parameters of the WSN, secondly analyzes the QoS parameters such as energy efficiency, packet loss rate, throughput and transmission latency in three kinds of typical topology structures, thirdly builds up a general simulation platform for the WSN using NS2, and finally simulates and analyzes the main QoS parameters of the WSN on the platform. The simulation obtains effects on QoS parameters under different kinds of topology structures.
