摘要

无线传感器网络(WSN)是一种自组织、能量受限的自组织网络，由专门的节点(称为mote)组成，这些节点可以感知某个区域内的某些现象。无线传感器网络可能采用通用或专用路由协议，节点分布随机，感知和收发模式不可预测，且不可替代能量有限。本文试图比较按需响应路由协议(AODV)和主动路由协议(DSDV)。从数据包传送率、归一化路由负载、延迟、最大和平均能量等关键性能指标对其性能进行了研究。利用具有附加Mannasim功能的Network Simulator 2 (NS-2)，通过改变节点分布面积和节点密度，采用专门的能量模型进行对比分析。分析揭示了每种协议适合的特定应用程序。

PERFORMANCE ANALYSIS OF ROUTING PROTOCOLS FOR WIRELESS SENSOR NETWORKS

A Wireless Sensor Network (WSN) is a self-organizing, energy constrained ad hoc network consisting of specialized nodes called motes sensing some phenomenon in an area. WSN may use generic or specialized routing protocols with random node distribution and unpredictable sensing and transceiving patterns with the constraint of limited irreplaceable energy. This paper attempts to compare on-demand reactive routing protocol (AODV) against proactive routing protocol (DSDV). The performance is studied in terms of key performance metrics which include packet delivery fraction, normalized routing load, delay, maximum and average energy. The comparison and analysis is made using Network Simulator 2 (NS-2) with additional Mannasim capability using specialized energy models by varying area of node distribution and node density. The analysis unravels the specific applications for which each protocol is suited.
