This paper describes the concept of sensor networks which has been made viable by the convergence of microelectro-mechanical systems technology, wireless communications and digital electronics. First, the sensing tasks and the potential sensor networks applications are explored, and a review of factors influencing the design of sensor networks is provided. Then, the communication architecture for sensor networks is outlined, and the algorithms and protocols developed for each layer in the literature are explored. Open research issues for the realization of sensor networks are also discussed.
二是注意行文中Transition words的使用。Transition words就是在行文过程中，连接意义相关句子的词，如Therefore，thus，in particular等等。使用这些词，会使得文章连贯性好，逻辑性强，读起来一气呵成，自然会给审稿人好印象。下面是一个关于Transition words的一个总结，供各位虫友参考：
Transitions Study Sheet
Transitions for time:
before, afterward, after, next, then, as soon as, later, until, when, finally, last, meanwhile, during, at times, sometimes, oftentimes
Example: WWII broke out in Europe in 1939. During this time the United States remained neutral. It wasn’t until 1941, after Japan bombed Pearl Harbor, that the United States entered the war. After its entry, it was only a matter of time before the Allies defeated Germany and the Axis powers.
Transitions for place:
in the background, in the distance, beyond, behind, above, below, in front of, elsewhere, in the middle, to the left, to the right
Example: My favorite painting is Botticelli’s Birth of Venus. In the middle of the painting stands Venus, the Roman goddess of love, standing on a seashell. She floats majestically above the beautiful water below her. To her left a figure representing wind blows fierce clouds of wind in her direction. To her right a figure behind her attempts to cover her with a blanket and protect her. It is a truly breath-taking piece of art.
Transitions for examples:
for example, for instance, as an example, like, specifically, consider as an illustration, that is, such as, similar, similarly
Example: Oftentimes people who study from history fail to learn from the mistakes of the past. For example, during WWII Hitler decided to invade Russia just before wintertime. This decision was the same decision Napoleon made over a hundred years earlier, and Hitler’s army met a similar fate. Had he learned from his history, Hitler might have avoided making this costly mistake and the outcome for the war might have been different. For instance, if Hitler had decided to invade England by sea rather than Russia by land, he might well have won the war.
Transitions for emphasis:
chiefly, equally, indeed, even more important, in particular, most important, without a doubt, indubitably, unquestionably, definitely
Example: Without a doubt, Chinese food is one of my favorite cuisines. Although I find Japanese and Thai food equally delicious at times, Chinese food is definitely my favorite Asian cuisine. In particular I enjoy the spicy Szechuan style of cooking commonly found in Chinese food.
Transitions for restatement:
in short, that is, in effect, in other words
Example: When I asked my girlfriend to marry me she said, in effect, that she wouldn’t be ready for marriage until after she completed her PhD program. At first I was crushed, that is, I felt like she said no because she didn’t love me anymore. However, after she explained her reasons to me I felt better and agreed with her. In other words, I came away feeling better than I had anticipated.
Transitions for comparison:
similarly, likewise, also, the same as, different than, opposite, unlike, instead
Example: When my older brother was deciding where to go to college he spoke to my father about where he should go. Not surprisingly he went to the same school my father did, MIT. When it was time for me to choose a college I did the exact opposite. I didn’t ask my father where I should go, and as a result, I didn’t also go to MIT like he and my brother did. Instead I went to UCLA.
Transitions for concession:
although, of course, admittedly, true, doubtless, granted that, no doubt, indubitably, without a doubt, definitely, certainly
Example: Some people might be surprised to learn that the two most successful NBA teams of all-time are the Boston Celtics and the Los Angeles Lakers. Although neither of these teams is very good right now, they are the two teams with the most champions in NBA history. The Celtics definitely had the best streak of these two teams; winning eight championships in a row at one point. Admittedly there is always the chance that some future team could break this record, but this seems unlikely. Of course no one can predict the future with any certainty.
Transitions for consequence:
thus, so, then, it follows, as a result, therefore, hence, consequently, accordingly, because
Example: I’m sorry, but I can’t let you turn in your homework late because it wouldn’t be fair to the other students. As a result your grade has dropped lower and you are now failing the class. Consequently you need to get 100% on the final so you can pass the class and then graduate from CAS. Therefore, I suggest you study very hard so I don’t have to fail you. Good luck!
Transitions for conclusion:
to sum up, in summary, finally, therefore, thus, in conclusion, to conclude
Example: Finally, Beijing has a lot of nice places to shop that appeal to tourists. To sum up then, Beijing is a wonderful place to visit because it has beautiful parks and historical monuments, friendly people and lots of nice places to shop. Thus any travelers who are planning to come to China should definitely visit Beijing during their stay.
Transitions for addition:
furthermore, in addition, besides, next, first, second, moreover
Example: UCLA is a wonderful university to attend as an undergraduate. First, it is respected academically and is well-known for its high standards of education. Furthermore, UCLA has a strong network of alumni who often recruit students to come work for them. Moreover students who do such work as undergraduates often receive jobs with these same companies once they graduate. In addition to these two benefits, UCLA also has exciting sports teams that are fun to watch. Besides, with so many good reasons to go to UCLA, why would you want to go anywhere else?
