摘要
为提高最小跳数路由(MHR)无线传感器网络的综合性能,通过仿真分析,揭示了传统最小跳数路由无线传感器网络存在的缺陷,极低开销地提取了改进传统最小跳数路由网络所需的相关信息,并讨论了可能的改进策略,给出了改进前后的性能比较。理论分析和仿真结果表明,利用廉价提取的网络行为特征信息对传统的最小跳数路由无线传感器网络进行改进,能提高网络的可靠性、能源有效性以及其综合性能。
In order to improve the general performance of Minimum Hop Routing (MHR) wireless sensor networks, with the help of simulation, this paper revealed the shortcomings of traditional MHR wireless sensor networks, dug out the required information at low expenses to improve the traditional MHR wireless sensor networks, discussed the improving policies, and compared the performances of the networks before and after. The theoretical analysis and simulation results imply that it will improve the data transmission reliability, energy-efficiency and general performance if we revise the traditional MHR wireless sensor networks by the information derived from network behaviors with low cost.
