as one crucial research directions of security, attacks against routing layer of wsns may cause the whole networks disabled . so it is significant to study secure routing issues of wsns 安全路由是安全问题的重要研究方向,针对路由层的攻击可能导致整个网络瘫痪,因此研究安全路由问题有重要意义。
the research subject of the dissertation is the key function layer of the cdn network-- route layer . from the point of the theoretical analysis and the computer simulation, the name-based route technology of the cdn route system is thoroughly studied 本文以cdn网络中的核心功能层??路由层为研究对象,从理论分析和计算机仿真的角度对cdn路由系统的基于名字路由技术进行了深入的研究。
the research is composed of three parts : in the first part, based on the research of issues related to security and routing, this thesis analyses the threaten of routing layer and the security of the existing typical routing protocols in wsns, and then draw a conclusion that gear surpasses others 主要包括三个部分:第一部分在对传感器网络安全路由相关问题研究的基础上,分析了路由层面临的安全威胁及典型路由协议的安全特性,得出gear路由综合性能较好的结论。
