Wireless Sensor Network

Wireless Sensor Network (WSN), which is made by the convergence of sensor, nested computation, networks and wireless communication technologies, is a novel technology about acquiring and processing information. It can be defined as an autonomous, ad hoc system consisting of a collective of networked sensor nodes designed to intercommunicate via wireless radio. Wireless Sensor Networks had been applied in a lot of scenarios and situations. Both academia and industries have shown great interestin Wireless Sensor Network.Wireless senor network differ from traditional wireless network in several ways: severe energy constraints, redundant low-rate data, many-to-one flows.The main capability of Wireless sensor networks is energy efficient. On the basis of the analysis of energy management of WSN, sensing data, data processing and radio communication are the main consumers of sensor's energy. The radio communication is the major consumer of energy. Although energy efficiency can be improved at various layers of the communication protocol stack, however, due to fundamental physical limitations, progress towards further energy efficiencv is expected to routing protocol.In this paper, the issues of the transmission efficiency routing protocols of wireless sensor network based trajectory are discussed. Based analysis of the routing protocols of wireless sensor network, this paper designs two independent routing protocols through considering transmission efficiency and network lifetime such as a based on Line Trajectory Transport Efficiency routing protocol and Transport Efficiency based on B-spline curve Trajectory routing algorithm.

Interspaces of the life

Most of the time you are supposed to leave a little bit interspaces for your own life, which just like the safety distance between the two vehicles——a little bit room for mitigation.Everyone wants to get cheap Lacoste POLO Shirts.

Heavy Traffic

In recent years ninny cities are faced with the problem of heavy traffic. People have to waste more time on their way home or to work and even might be involved in an acci dent. With the development of industry and population expansion, this problem becomes more and more serious.North face jackets are here for you!
　　One solution is to lay down more roads. The solution has many advantages. For ex ample, it can efficiently decrease the number of buses and trucks in many main streets. But it will take up so much land that crowded cities become more crowded. You can buy cheap north face jackets here.Another solu tion is to open up more bus lines. If more bus lines should be opened up,the number of bicles and cars in the main streets would be greatly decreased. But the disadvantage of this solution is that many people wouldn’t feel so convenient os they used to.Spyder jackets are very good!
　　In my opinion, the right solution to the problem is the combination of the two, thatis, to lay down more roads in spacious areas and to open up more bus lines in downtown.

City Life or Country Life

I am living in the suburbs of Taipei. So many people moved from southern Taiwan and settled there that this boom town has been very crowded.My family lies at the intersection of two cheap straighteners. Every day, we are bothered by disturbing noise, and exhaust fumes from passing cars. Besides, about 100 meters away from my house stands a famous night market, which attracts thousands of chi pink dazzle every night. The garbage-left-overs, fruit peels, dirty paper napkins is scattered on both sides of the streets. I think the life quality of this community is getting worse.I always dream of living in the country. The serene country life will certainly calm my nerves and slow down my pace of life. Early in the morning when you are awakened by the singing of the birds, you can breathe the fresh air and enjoy the beautiful chi hair straightener around you. In addition, people in the country are friendly and hospitable. They will invite you home for tea or chat with you as they work on the farm. How I wish to love in the country!
