Description: Recent advances in wireless sensor networks have led to many new protocols specifically designed for sensor net-
works where energy awareness is an essential consideration. Most of the attention, however, has been given to the
routing protocols since they might di?er depending on the application and network architecture. This paper surveys
recent routing protocols for sensor networks and presents a classification for the various approaches pursued. The three
main categories explored in this paper are data-centric, hierarchical and location-based. Each routing protocol is de-
scribed and discussed under the appropriate category. Moreover, protocols using contemporary methodologies such as
network flow and quality of service modeling are also discussed. The paper concludes with open research issues. 2003 Elsevier B.V. All rights reserved.

Description: Position location services will not only provide new customer options and products for
wireless carriers, but will also provide features that could di erentiate services in di erent
markets (i.e., di erentiation between PCS, cellular, and specialized mobile radio) [4]. Location
systems will also provide wireless carriers and vendors who use position location the
ability to charge for service based on location, within a particular cell site, or in a speci
c location such as an oce, home, or car. This will allow wireless service providers to
control customer usage by o ering cost incentives that match service plans for the wireless
infrastructure and networking resources. Platform: |

Description: 基于WLAN的酒店餐饮管理系统的实现.大多数酒店餐饮管理系统都是基于有线网络的，但这样
的应用模式存在如下问题：(1)布线受环境限制；(2)网络中的各
节点位置固定，可移动性差；(3)通信故障查找困难。而基于
WLAN的酒店餐饮管理系统就能有效地克服以上不足。具有不
受环境限制，自组织和灵活性强的优势，可以做到随时随地为
顾客进行及时周到的服务，例如无线点菜、无线上网等，进一步
完善了酒店管理的业务流程。
-Hotel Restaurant Management Based WLAN System. Most of the hotel and catering management system is based on wired networks, but this application mode the following problems: (1) wiring subject to environmental constraints (2) location of each node in the network of fixed , poor mobility (3) communication troubleshooting difficult. WLAN-based hotel restaurant management system can effectively overcome the above shortcomings. Constraints of a free, self-organization, and flexibility advantages, can be done anytime, anywhere to customers timely and thoughtful service, such as wireless ordering, wireless Internet access, and further improve the hotel management business processes.

Description: gps定位程序 测试通过，可以直接拿来用 GPS卫星提供了P码（精码）和C/A码（粗码）两种定位服务。P码为军方服务，定位精度达到3米；C/A码对社会开放，定位精度为14米。出于自身安全的考虑，美国先后实施了SA和AS政策。SA政策在C/A码中人为引入了误差，使定位精度下降到100米；AS政策则对P码实行加密。 由于GPS对社会开放，因此各类接收机、测量设备如雨后春笋般涌现，并广泛应用于各行各业，彻底改变了传统的定位导航方式.-gps positioning program testing by direct use of them GPS satellites provide two kinds of location-based services in the P-code (precise code) and the C/A code (coarse code). P code for military service, positioning accuracy of 3 meters C/A code of the open society, positioning accuracy of 14 meters. For their own security reasons, the United States has implemented a policy of SA and AS. SA policy is artificially introduced in the C/A code of the error, so that the positioning accuracy down to 100 meters AS policy is implemented in P-code encryption. GPS open society, the various types of receivers, measuring equipment have sprung up, and are widely used in all walks of life, completely changed the traditional positioning and navigation.

Description: In recent years, stepping with the popularization of smart phone and the
development of mobile communication infrastructure, the conditions for ubiquitous
computing society become more and more complete. In the vision of ubiquitous
computing society, LBS (Location Based Service) that provides an added value to an
unprecedented user experience has been paid a great deal of attention by mobile
operators all over the world. As the core technology for LBS, various positioning
systems have been studied extensively. For the outdoor environment GPS is mature
and common. However, the performance of GPS in indoor environment is bad.
Moreover, currently there is no technique whose accuracy and cost are appropriate for
deployment in huge areas. -In recent years, stepping with the popularization of smart phone and the

Description: FIDO的认证协议：UAF/U2F
身份管理是一个范围比较广，有层次化，包含很多内容，FIDO处于身份认证的位置，基于风险管理的认证。解决了哪些问题：第一公里 -人的身份的识别（很多方式）+第二公里（有open ID、SAML解决），UAF和U2F是互补关系，并不矛盾。
UAF的原理：传统用户的密码是放到服务端，每次提交服务端，服务端进行认证。-FIDO authentication protocol: UAF/U2F identity management is a relatively wide range, there are hierarchical, it contains a lot of content, location FIDO in authentication, authentication based on risk management. Which problems: first identifying km - the identification of persons (in many ways)+ second kilometer (have open ID, SAML solve), UAF and U2F are complementary, not contradictory. UAF principle: the traditional user' s password is placed in the service side, each submission server, the server for authentication. Platform: |
