摘要
建立了一个以数据为中心的路由协议模型,在NS2仿真平台上对其进行了验证分析,并将其性能与传统端对端路由机制进行了比较.通过数学分析和仿真方法得知,在大规模高密度无线传感器网络中以数据为中心的路由协议能更有效地节约能量,延长网络的生命周期.
In this paper, a data-centric routing protocol model is built, then the model is verified and analyzed on the NS2 simulation platform, and the performance of the new model is compared with the traditional end -to-end routing schemes. It can be shown that the data-centric routing protocol can save energy and prolong the lifetime of large-scaled and dense wireless sensor networks by simulation and mathematical approaches.
