【摘要】 无线POS(Ponit of Sales销售终端)支付系统是近年来产生的一种电子金融业务,采用传统的传输协议,则会造成POS数据传输系统的交易时间长、保密性差、传输可靠性不高、带宽利用率低的现状。针对这个问题,文章设计了此系统专用的通信协议—WPTP(Wireless POS Transfer protocol)协议,并介绍了如何在网络仿真软件NS2(Network Simulator-2)里添加自己设计的模块并给出仿真此协议的步骤。更多还原

【Abstract】 Wireless POS Payment System has emerged as an electronic financial services in recent years. Using the traditional transfer protocol, has resulted in POS transaction system a lot of questions such as working for a long time、low transmission confidentiality and reliability、low bandwidth utilization. In order to solve the problem, this paper design a new special communication protocol —WPWP, and then introduce how to add our own module in the network simulation software —NS2, and give the steps of how to simulate this new protocol.更多还原
