Research on Load Balance Routing in Ad Hoc Networks

Firstly, the research status of load balance routing protocols of mobile Ad hoc networks is introduced. And analysis and comparison of different protocols are conducted. Then non-coordinated distributed scheduling mechanism of Ad hoc networks is presented. In such mechanism, interference signals caused by hidden terminal problem and exposed terminal problem will affect the transmission of packets, and furthermore, degrade the performance of the whole network. Based on above analysis, a new load balance routing strategy is presented, considering channel interference, which is caused by hidden terminal problem and exposed terminal problem, as node load. Thereby, link performance can be improved by avoiding the nodes which cause unexpected hidden terminal problem and exposed terminal problem in the routing selection of packets. Theo- retical analysis and simulation results demonstrate that this strategy can improve the quality of packets transmission, reduce delay and achieve load balance between nodes.In the end, a conclusion of the thesis is made and further research contents and directions are put forward.

deep night

One day when I was leaving the teachers’ office, it was already in deep night. The surroundings were in complete silence and frightening darkness. Here is the best northface outlet!Even though I was so reluctant to go to that cold world, my feet were out of control and they went directly to my dormitory. At the dormitory gate, I was startled to find that there still existed a little light glimmering in the darkness, so faint but yet so clear. In that setting, it seemed so unique and powerful. Just in the guidance of the light, I went to the room without any obstacles. All of my roommates had been in sound sleep, leaving the world in calm and the rosy light. Unconsciously tears rolled down my cheeks, and those were tears of happiness and gratitude. “Just because someone doesn’t love the way you want them to, doesn’t mean they don’t love you with all they have.” This is your favorit chi hair straightener!This was a belief that I had borne in mind for a long time, but not until then had I understood the true meaning of it.
Sometimes someone may not know how to show their feelings to you, but just give yourself a few minutes to think over and you will sense the essence beyond this superficial indifference. Since we all like tranquility, both in environment and in our mind, our friendship is bound to be a common one. I think these ralph lauren polo shirts are the beginning of a beautiful friendship.Neither do we have passionate feelings, nor do we have sharp changes in life, and even anger leaves us away. While in our deep feeling, we are bound together by a kind of invisible power. I am sure that it must be love and care towards the others, from which the healing energy emanates. It is just this kind of power that melts all the misunderstandings and unpleasantness. Thus it makes us think together, laugh together, and even cry together.
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

A True ‘Love’ Story

Mr. Mean works and lives in X city of Northwest China. He usually says to chi hair straightener, ‘I am a journalist, who takes a very important position in newspaper GJ office. I also have an elder brother who is an official of high position in C city and who can easily offer me a position in the government of chi straightener. If you have some problems, get contact with me, and I will help you with my total effort.’ Everybody believes that he is a kind man with great ability. But nobody has ever seen one article of his in newspaper GJ.
Mr. Mean is about thirty and still has no girlfriend. His parents frequently impose pressure on him in order to urge him to get married quickly, and he therefore feels worried. He then tells everyone that he needs and wants wife and expects they will one day introduce him a suitable lady. He emphasizes, ‘do not forget to tell them about my chi straighteners and my brother.’
One day a warm –hearted woman introduced him a 21-year-old girl Miss Disgusting, who is an acquaintance of her sister and who is a temporary nurse in a small hospital of a neighboring town. At first the go-between was afraid the girl would not take a fancy to Mr. Mean, for Mr. Mean is too short and is a little lame. But after reconsidering, he thought it is possible, for Miss Disgusting has no diploma whereas Mr. Mean has a Bachelor degree and a powerful brother.
