Algorithms in Wireless Sensor Networks


Wireless Sensor Networks(WSNs),which integrate the sensor,micro electro mechanism system(MEMS),distributed information processing and wireless communication,become one of hot research topics in the current Information Technology field.As a result of its inherent advantages,such as self-organization,wide coverage,high fault-tolerance and high accuracy measurements,as well as the features of low cost,low power,flexible deployment etc,the WSNs are applied ranging from the military areas to the abundant civil areas.The dissertation deeply studied the localization and target tracking problems in wireless sensor network,including node self-localization,the target tracking problems and so on. Based on Distributed predictive tracking(DPT) algorithm,Dynamic cluster predictive tracking (DCPT)algorithm is presented which improved the accuracy of target tracking and network life.Track the target by waking up the nodes in next one-hop radius.With moving of target, the cluster structure has also been constantly changing to avoid unnecessary energy consumption by waking up node blindly.The main contents of dissertation are as follows:(1) Optimize the cluster structure and operation mechanism.Improve the positioning accuracy of target through increase the number of node in cluster to acquire more information of target,the precision and accuracy of target predictive increased corresponding.To avoid network 'black hole',algorithms select the node full of the most energy as the cluster-head node,so as to achieve balanced energy consumption and improve the network life.(2) In positioning process,calculate the objective's specific location in the way of introducing the target signal strength as a weighting of 'centroid',so that further improve the tracking accuracy.(3) Location prediction method make use of macro-prediction and micro-prediction which combines a double prediction method to forecast the target location of the next time, start the forecast position node in the moment of objective leaving this cluster,which reduce the probability of missing of target.(4) Taking into account the various unforeseen circumstances,algorithm set up exception handling which Enhance the robustness of the system.Such as the target missing,cluster head death,etc. The experimental results show that,the half life of DCPT is higher about 30%than that of DPT,positioning algorithm proposed in this paper under the same conditions was significantly superior to the literature of the location algorithm.

Another Interpretation of Friendship


Never before had I imagined that one day I should have the opportunity to live with so many girls and yet never before had I been confident in myself that I would be able to get along with them harmoniously for four years. The very act of approaching my new dormitory made me frightened and bewildered. With what kind of expression should I face them? Do you love cheap north face jacket?Would a single “hi” be proper? Would they accept such a plain girl like me? All the questions haunted my mind. Harboring such a complex and uncertain emotion I pushed the door open.
I was about to greet my new roommates, but suddenly I felt that I had a lump in my throat. They did not appear to have the same preoccupations that I had. They just coped with their own businesses, sorting out their clothes, and making arrangements for their future life. Thus tranquility became the dominant note in the dormitory.You can buy cheap north face jackets here.
To my surprise, facing such a situation, I did not feel a sense of disappointment. On the contrary, I even felt a little bit happy, since I had been long expecting a tranquil environment. With the elapsing of time, we got to know each other deeper. I was pleased to find that in deep soul we all belonged to the same pattern----reserved as we were, we all set high our horizons and never stopped pursuing our dreams. Somehow I often thought that it was just the arrangement of the fate that brought us together, since we seemed so alike.
However, not long before this kind of harmony was disturbed by my own upset of mind. During that period, because of my working tasks, each day I had to stay out for a long time, unable to communicate and exchange ideas with my roommates. When I was engulfed in the state of confusion and misery caused by the heavy burdens, I found no one to turn to help. Do you want this pair of nike trainers?What I was concerned about seemed to have nothing to do with them and what they were doing and talking about seemed so far away from me. I often dreamed that they were on top of a hill, overlooking me with eyes filled with incomprehension. While I, standing at the foot of the hill, tried my utmost to reach them, only to be left in despair. How I wished that they could say something even nonsensical to me! How I wished that they could be another type of people with a clear demarcation between what to hate and what to love. However, it was impractical, since they were destined to belong to the group that seemed indifferent to everything. While one incident changed my mind and made me cherish this kind of calm better and more confident in our friendship.
Don't cry, smile
you are my sunshine
single is simple,double is trouble
Life is like a boat
always together,forever apart

Olympic in 2008


"The Games of the 29th Olympic in 2008 are awarded to the city of Beijing.You can own those chi straighteners." The International Olympic Committee ed the Chinese capital as the 2008 host in Fridays vote during Juan Antonio Samaranchs last IOC session as president.The attraction of staging the Games in a country which has the worlds largest population, as well as huge economic potential, won the IOCs heart. Beijing defeated four other bidding cities, including Toronto and Paris, to secure the countrys first-ever Olympics. Osaka was the first city to go out, and it only took one more round for Beijing to win the Olympic race. I think these ralph lauren polo shirts are the beginning of a beautiful friendship.The announcement, read out by the 81-year-old Samaranch, was answered with wild jubilation from the Chinese delegation in Moscow, and with fireworks in Beijing.IOC senior member Kim Un-Yong said after the voting that Beijing deserved the Olympic Games.Oh,Jerry,don't let's ask for the moon.We have the ralph lauren polo shirts. "Beijing is capable of staging a great Olympic Games," said the 71-year-old South Korean. "The result wasnt a surprise to me." With the motto "New Beijing, Great Olympics", Beijing promises to host a "Green Olympics", a "Hi-tech Olympics" and the "Peoples Olympics". The 3,000-year-old city is becoming a truly international city and showing a new, vigorous image through its ongoing economic reforms. Beijing enjoys the widest popular support among the five bidding cities. A Gallup opinion poll commissioned by the government showed 94.9 percent of the public in favor of it. The IOCs own surveys found support even higher. The Chinese government has pledged to spend 20 billion U.S. dollars building sports complexes and refurbishing the Beijing infrastructure. There are plans for a new exhibition center with twin skyscrapers that could be taller than any in the world.

satisfied

So the two people met and both were very satisfied. Five days later, the two lived together in the room Mr. Mean rented. Another five days later, Mr. Mean find a temporary job in a hospital of polo shirts. It seemed that the two were in a harmonious relation. The go-between was ralph lauren polo shirts, too, for he thought he had done a good deed.
Forty days later, Mr. Mean came to the go-between’s office. To everybody’s great cheap ralph lauren polo shirts, he had many wounds in the face and on the neck, which were obviously the works of woman’s scratches. And to everybody’s greater surprise, he asked the go-between for some money to borrow. His reason is this: ‘I have spent 3000 Yuan or more on the girl. I bought modern clothes and cosmetics and her new job cost me much.’ The go-between was unwilling to lend him, for Mr. Mean was not his good friends, but just his acquaintance. Mr. Mean said, with a tone of begging, ‘I just borrow for a few days. As soon as my salary is given to me at the end of this month, I will return. Do you have 500?’ The go-between said, ‘no.’ ‘Do you have 300?’ ‘No.’ ‘100?’ ‘Sorry. I forgot to take money with me today.’ Then Mr. Mean asked one of the go-between’s colleagues, ‘have you?’ The colleague, who didn’t know him at all, got annoyed by him and said ironically, ‘I have here only ten Yuan and a few fen. If you want, I will lend you.’ ‘O.K. I will return later.’ Mr. Mean said happily. The man gave him ten Yuan. But later every time he got to the office, he looked as if he had never borrowed any money.
