Why Has Tourism Become Popular

In recent years, tourism becomes more and more popular with Chinese people. People discuss tourist plans with each other, book train and plane seats well ahead of time, lest they should all be booked up. The first reason of this tourist craze should be attributed to the change within people's mind. People like to relax themselves in their holidays. Enjoying oneself froin time to time is replacing the previous belief in continuous hard work. The second reason is the swelling of their wallets, which enables people to afford the tourist expenses. In response to the travelers' need, local authorities try to exploit their own characteristic tourist resources in order to make profit on tourism. As a result, tourism becomea more and more popular. I also enjoy touring, both for relaxation and enrichment of knowledge. I hope we will be provided with more and more scenery spots and interesting holiday resorts.
I am your sunflower and you are my sunshine
I believe in myself
never say never
dreams will keep me young
never grow old

trained

Don't jump in to save a drowning person unless you are a trained lifesaver. The victim may pull you under.
　　Instead, try to tossa life preserver if you have one. Anything that will float can save the person’s life. A beach ball, a vacuum jug, or a picnic chest will also help. The National Safety Council points out that many drowning could be prevented if people knew all the common objects that float well enough to help a drowning person.
　　If you are in a boat, or you can find one, use the boat to try to reach the person in trouble. Turn the boat so the victim can grab the stern. Don’t stand up to help the victim. Stay seated so the boat won’t overturn. Try to balance the boat as the person climbs aboard. If the boat overturns, stay hanging on to the side for a while to relax before trying to right it.
I wanna be the place you call home
What makes the desirt beautiful
First need your hand and forever can begin
I am slow walker but I never walk backward
love and be loved in return

Congestion Control protocol

This paper introduces the Ad hoc wireless communication networks, as well as its scope of application and the status of study . Qn the basis of understanding Congestion Control protocol, it point out the problem: Traditional TCP protocol 's design was just wedding dresses 2010 concerning about wire network .It Contributes the loss of data discount wedding dresses package to network congestion and employ congestion—control process to solve the problem .The traditional TCP protocol is not Appropriate for the speciality of Ad hoc network environment .As the loss of data Package in Ad hoc network may be resulted from node movement, error of wireless Channel or something else .Traditional TCP protocol can not correctly find the Reason for Package loss and just conduct cheap polo shirts congestion—control, leading to the decrease of TCP performance .So it is crucial to improve traditional TCP to make it fit into Ad hoc network.In this paper, the author have analyzed the effect on TCP performance caused by wedding dresses 2nd Ad hoc network And the existing scheme has been classified and summarized from two aspects of datalink layer and network layer, which pointed out that the effect on TCP hot women's dresses performance induced by datalink layer was mainly caused by hidden terminal and exposed terminal. And then the author divided in two improved schemes: network-oriented and end-to-end network and adressed the comparison among schemes.According to the problem of datalink layer, adding properly the minium congestion window could effectively improve data throughput, hidden terminal and exposed terminal so as to improve the instability of TCP, which was testified effectively though the simulation results. According to the existing scheme, the author have proposed a new end-to-end scheme, though which the receiver could speculate network situation according to the value of propagation delay and explicitly notify the sender whether it will has a congestion or not depending on the returned ACK. So the advantage of the scheme is not to introduce excess computing cost on the receiver. It showed it effective via the simulation results.
