On the Delay of Geographical Caching Methods in Two-Tiered Heterogeneous Networks

Abstract We consider a hierarchical network that consists of mobile users, a two-tiered cellular network (namely small cellsand macro cells) and central routers, each of which follows a Poisson point process (PPP). In this scenario, small cells with limited-capacity backhaul are able to cache content under a given set of randomized caching policies and storage constraints. Moreover, we consider three different content popularity models, namely fixed content popularity, distance-dependent and load-dependent,in order to model the spatio-temporal behavior of users’ content request patterns. We derive expressions for the average delay of users assuming perfect knowledge of content popularity distributions and randomized caching policies. Although the trend of the average delay for all three content popularity models is essentially identical, our results show that the overall performance of cached-enabled heterogeneous networks can be substantially improved, especially under the load dependentcontent popularity model. Besides, Because of the limitation of research conditions, the total network delay, network cost and optimization of network parameters are not analyzed. Keywords: edge caching, Poisson point process, stochastic geometry, mobile wireless networks, 5G Introduction It is known that content caching in 5G heterogeneous wireless networks improves the system performance, and is of high importance in limited-backhaul scenarios. Most existing literature focuses on the characterization of key performance metrics neglecting the backhaul limitations and the spatio-temporal content popularity profiles. In this work, we analyze the gains of caching in heterogeneous network deployment, and consider the average delay as a performance metric. Firstly we use passion point process (PPP) method to build the model. This heterogeneous network consists of mobile terminals (users), cache-enabled s mall base stations (SBSs), macro base stations (MBSs)

以下为爱麟霖/(Curlylin)倾情奉献,需要的朋友可以参考一下 7. Friendship (Listening and Speaking Course, Unit 3; Integrated Course, Unit 2) 1) Do you have many friends? What kind of people do you want to make friends with? Why? Yes. I’d like to make friends with loyal people. In my opinion,a friend is a person who can share his/hers happiness with you, who can lend you a shoulder when you cry,who can give you a hand when you are in trouble without asking for anything in return. In a word,a friend in need is a friend indeed, I think a loyal people can do the things which were mentioned above for his/hers true friend. So I prefer to make friends with loyal people, and I also believe I am a loyal people who you can make friends with. 2) How do you make friends? Please comment on “a friend you buy isn’t worth the price”. First,I’d like to talk to him to find out whether we have the same interest with each other. If the answer is YES,then we have the foundation to develop a friendship. The next days, all we need to do is to treat each other by heart and soul. 3) How valuable is friendship in a person’s life? How can we keep friendship alive? As for me, I regard friendship as a very important part in my life.Just imagine a life,there’s no one to be your friend. What life could be if you had no friend to talk to , no friend to comfore you and cheer you up when you were having a hard time,no friend to lend you a hand when you needed help …… Life without friends is unthinkable ... We have to do hard work to build up and sustain our friendship. First, let your friends know that you really care about them.It’s important to give some cues to your friends. Be sure your friend knows that she is cared about.Second,try to be with your friends when they are in trouble when they need you. Keeping friendship alive is not only to say some sweet words,but need some real action. 4) What does friendship mean to you? What kind of friends do you think are true friends? It's a fantastic experience in whole of my life. Friendship to me is what water to fish.I can't live without a real friend. 2问见(1) 5) How can we get along well with other people? To begin with, we need to be honest with others and always say what we mean. Lies will surely make people stay far away from us in the long run. After all,honesty is the best policy. Second, we have to be humble enough. If we are proud in public, we can hardly win other's respect, not to mention "friendship" . Finally, we must not be selfish. We should learn how to show concern for others. As long as we abide[?'ba?d] by what is mentioned above, we will find it easy to get along well with others.

大学英语口语考试试题-10个口语话题(期末)

Topics for Oral test 1. Which great leader do you admire most? What qualities did/does he/she have? bill gates 2. Which do you cherish more, your friendship with a good friend or your romantic relationship? obviously, friend is easy to make, but lover is kind of hard to seek for. Since relationship between friends might be not that close compared to romantic relationship, I will probably take it serious and cherish this sweet relationship. Also, I believe that my friends will support me and our relationship won’t be tense and freezing because of this. As the Chinese saying goes, once you got a boyfriend or a girlfriend, you may leave your friends out of your mind. I partly agree this, and when I fall in love, especially at the very beginning, I think I will cherish it more than friendship. 3. What factors would you consider first if you were to find a job (even a part-time job)? I will first consider whether this company and the offered position is high potential. I think high potential is a quality that is vital for the company’s future development and its personnel’s self improvement. Every one need a room to promote and realize one’s self-value. Another factor I concern is—its location. I’d like to work and live in big cities because big cities offer so many opportunities and a higher salary while small cities can’t. 4. Whom do you usually turn to when in trouble, vour parents or your friends? They know me better than anyone else and their vision is wide, their thoughts are mature.

东南大学英语语言文学专业考研经验

宏韬东大考研网 2014东南大学英语语言文学专业考研经验 现在有点空闲时间了,可以写点经验帖出来借大家参考。回想复习,初试,复试的经历不是很清晰了。但是想要告诉后来的同学们,希望可以有帮助。 记得是2007年的六月份决定了考研究生。相对于很多人来说应该比较晚了。考研是一定要选择学校的,当时选择上外,是因为这是英语领域很强的学校了,还有一个原因是大学在北京,不是很喜欢它,所以想去上海了。另外的原因是上外不考文学和语言学,这两门是我学得不好也很头疼的科目。我最喜欢翻译。更有一个重要的原因是这个论坛让我喜欢上了上外,喜欢这里的人们,他们很热情,善良,耐心。 买书是一件麻烦的事情,因为很多的书不能直接买到,是要预定的。而且还有书是买不到的,就像张培基的第一辑《英译中国现代散文选》。所以买书用了很多时间。我想如果在大城市里应该有很大的书店或者书城,就可以买到需要的书了。我的书不是一次买齐的,而是陆陆续续买回来的。书目是从这个论坛了解到的,所以心里很感谢学姐和师哥们。初试买的书有很多,数一数大概有十几本吧,我想有很多人买的应该更多吧。 英语 《汉英翻译基础教程》杨晓荣编著中国对外翻译出版公司(1,2,5,6,7,8)买了六本,还有7,8册答案书,所以是8本。很认真的看了7,8册,没有看1,2册,简单的看了5,6册。 《大学英汉翻译教程》王治奎山东大学出版社这本书是很容易买到的。 《大学英语语法与词汇》袁晓宁主编北京外语教学与研究出版社 等一些重要的参考书 法语 《新大学法语》(1)周林飞、李志清编高等教育出版社这不是我大学学习的课本,所以还是很认真的看了一遍,觉得内容比较多,有点难。 《大学法语考研必备》(世界图书出版公司)这本书是很好的,我很认真的把每一题都做了,看了两遍。 政治 《2007考研政治理论考试参考书》这本书很好买的,好好第看一遍很重要。 《政治理论基础过关2000题》认认真真的看了一遍,但是没有记住。 《2008全国硕士研究生入学考试用书--陈先奎政治考前大串讲》这本书很厚,不详细,建议不要买了。 《形势与政策》忘记了哪里出版的,我想任意的一本内容都是差不多的,讲的内容很多,很繁琐。但还是要好好看的。 还有一本《考研复习精编》,因为这是我报考的宏韬东大考研网的辅导班出的书,对我帮了很大的忙。 这就是我买的所有的书了,不是很多。但是我从小的时候就有认真看书的习惯,记得每次考试之前会把课本从头到尾认真看一遍。所以这几本书是认真看了的。

Friendship is absolutely crucial for us. We have to do hard work to build up and sustain friendship. Here are some important ways to keep friendship alive .First of all, let your friends know that you care about them. If you can't be there at the given moment, say something like, "I wish I could be with you. May I call you tomorrow " Be sure your friend knows she's cared about. Second, try to be with your friends when they are in trouble. Remember troubled people are most in need of their friends to stay around. The last but not the least, keeping friendship alive is to say to your friends "I miss you and I love you ". Remember it right for college students to have tattoos Nowadays many college students like to highlight their personalities, to be their own. They have taken special ways to show their personalities. For example, some college students who are tattooed think tattooing is cool and shows great personality. But teachers and parents do not think tattooing is right for students. They believe to be a student you should dress like a student--no tattoos, of cause. Some people even believe that those who are tattooed are not good students. As far as I am concerned, although many people can not accept students’tattooing, nothing is wrong with tattooing. College

东南大学研究生一年级学术英语教科书答案chapter9

Unit 9 referencing 1.1 Pre-reading tasks Why do we have to reference? When you reference correctly you are demonstrating that you have read widely on a topic. You are also supporting your hypothesis with comments from expert authors. This lends credibility to your own work. Also, by correctly referencing, you allow the marker or reader to follow-up your refer ences and to check the validity of your arguments for themselves. This is an important part of the academic process as it leads to student accountability. How do we usually reference? (In-text citation and reference list) How do we create a reference list? When creating a reference list, the sources should be listed alphabetically by author’s surname, should be left justified, and the references should never be preceded by a bullet-point or number. Where the author is anonymous or unknown for any one source, insert that source in the alphabetical list using the title of the source instead of the author’s name. All sources should be listed together; there should not be separate lists for books versus journal articles versus electronic sources. The reference list should be on a separate page from the rest of the assignment and should be simply titled ‘References’ or ‘Literature Cited’ and the t itle should be in the same font and size as the other headings in your assignment. How many referencing styles do you know? (APA, MLA etc) 1.3.1 Differences between Science and MLA Science MLA Book reference order of publisher and place. (publisher, place) Punctuation mark. Information is segmented by comma. Publisher, place and year in blanket. Example: J. B. Carroll, Ed., Language, Thought and Reality, Selected Writings of Benjamin Lee Whorf (MIT Press, Cambridge, MA, 1956) 1. order of publisher and place. (place:publisher) Punctuation mark. Information is segmented by full stop. Example: McDonagh, Sean. Why are we Deaf to the Cry of the Earth. Dublin: Veritas, 2001. Journal reference 1. Order of first name and last name: first name. Last name 2. Order of year and page: Page (year) 3. Punctuation mark. 4. Example: N. Tang, On the equilibrium partial pressures of nitric acid and ammonia in the atmosphere. Atmos. Environ.14, 819-834 (1980). 1. Order of first name and last name: Last name, first name. 2. Order of year and page: (year):Page . 3. Punctuation mark 4. Example: Mann, Susan. "Myths of Asian Womanhood." Journal of Asian Studies. 59.1 (2000): 835-62. 1.3.2
