1. INTRODUCTION
1.1 Overview A mobile ad hoc network or MANET is a kind of wireless ad hoc network, which is the infrastructure wireless networks where each user directly communicates without an access point or base station. It is a self-configuring network of mobile routers connected by wireless links with no access point. Nature of mobile device in a network is autonomous. Due to these mobile devices are free to move. In other words, the mobile ad hoc network is infrastructure less wireless network. The Communication in MANET is take place by using multi-hop paths. Nodes in the MANET share the wireless medium and the network topology changes dynamically. In MANET, breaking of communication link is very frequent because the nodes are free to move to anywhere. The density of nodes and the number of nodes are depends on the applications in which we are using MANET.

Fig-1 Ad-Hoc Network

In figure a simple ad-hoc network shown with 3 nodes. Node1 and node 3 are not within range of each other; however the node 2 can be used to forward packets between node 1and nodes 2. The node 2 will act as a router and these three nodes together form an ad-hoc network.
1.2 MANET Characteristics
Distributed operation: The control of the network is distributed among the nodes; there is no central background for the control of operations. The nodes should cooperate with each other and communicate among themselves and each node acts as a relay as needed, to implement specific functions such as routing and security
Multi hop routing: When a node want to send information to other nodes which is out of its communication range, then the packet should be forwarded via one or more intermediate nodes.
Autonomous terminal: In MANET, each mobile node could function as both a host and a router because is an

Holes

...very scary in this book. Being with friends can help. Stanley Yelnats did not always have friends. At the beginning of Holes, Stanley was scared, but because of Zero he was brave by the end. Stanley was scared in the beginning because he did not know anybody. He was the new guy at Camp Green Lake. He had to go to the camp because they thought he has stole shoes, but he did not steal them. He thought he was going to get hurt. When he was in his cot, he thought it would break. Stanley was afraid of what would happen because of the curse. The curse was from his “no good, dirty rotten, pig stealing, great-great grandfather”. The curse would effect Stanley’s life immensely. Stanley was very scared because of all the things at Camp Green Lake and he did not have any friends to talk to in the beginning. At the end of the book, Stanley was brave because of Zero. Zero helped him have confidence. Everyone at the camp trusted Stanley. One of the campers named Squid asked Stanley to call his mom and apologize for him. Stanley taught Zero how to read and write even though other campers made fun of him. Stanley found his way back to camp with the help of Zero. They did not have any water, only had onions to eat, had to walk really far and they were alone. Zero and Stanley help each other even in the worst times possible.

...CAE Software of Twin-Tubes Shock Absorber Outer-Characteristic Changcheng Zhou, Jie Meng School of Traffic and Vehicle Engineering Shandong University of Technology Zibo 255049, China greatwall@sdut.edu.cn Abstract The pathway throttle and local throttle loss of oil flow in telescopic shock absorber were analyzed, and the pathway loss coefficient and equivalent length of piston holes were studied. According to the thickness and the pre-deformation of throttle slice, and the throttle holes area, the velocity points of valve opening were researched and the analytic formulas of shock absorber velocity when valve opening were given. With the velocity points of valve opening, the model of shock absorber outer characteristic was established by piecewise linear math function. Based on this, the CAE software for shock absorber outer characteristic was developed. A practical example of simulation of shock absorber outer characteristic was given with this CAE software, and the performance test was conducted to verify the CAE software. The results show that the CAE software is reliable, and the values simulated is close to that tested. 1. Introduction The shock absorber of automobile is one of the most important components of suspension system, and plays a vital role in the driving process of vehicles[1,2].

Sachar Holes

...Holes is a novel which was created by Louis Sachar. The novel won awards for the 1998 U.S. National Book Award for Young People's Literature and the 1999 Newbery Medal for the year's "most distinguished contribution to American literature for children". It is a great novel that my class read and hear are the top 3 reasons why it is a great novel. The three things that make it a great novel are the link ups, the backtracking and the character descriptions that Louis Sachar wrote. My opinion on why Holes is a great novel is because of all the link ups in the story. The link ups in the story bring the story together and it is genius of Louis Sachar to do this because it make the audience want to read more. In the book Elya Yelnats gets cursed by Madam Zeroni until the 4th generation when Stanley Yelnats carries Hector Zeroni up the mountain and sings the song. After, the curse is broken. Trout Walker looks for the treasure that kissing Kate Barlow stole from Stanley Yelnats the first but when he has a baby girl she digs as well. Then she becomes the warden of Camp Green Lake and makes the other boys dig for the treasure. Then when Stanley and Hector find the treasure, they find Stanley’s name on it so they get to keep it....

...be able to produce a drill that will be able to go down that deep and rescue the miners? Will it take them three or four months to drill a hole before the miners are free?  Thirty-Three Chilean workers trapped in a mine Thirty-three Chilean miners trapped in a mine in San Jose under Atacama Desert with very little oxygen, food and water. All thirty-three miners were underground for 17 days before their first contact from the outside world. Codelco mining company is a state owned company in Chile, that was in charge to drill three small bore holes into the ground which was the first break through to reach the workers, allowing the rescuers to be able to communicate with them and send them food and medicine. The companies plan was to bore a rescue hole that would pull the miners up from 2,300 feet of the earth. First, they have to drill a pilot hole in the earth that is similar to a borehole. This would make the hole wide enough to establish some form of communication, sending down a camera to see how the miners were holding up 2300 feet below the earth surface, allowing them to speak into the camera to their family members. After drilling the first phase, they will than use another cutter machine that is bigger and drilling in the same spot as the previous holes allowing the holes to become wider. The miners have to aid by...

Tears of a Tiger and Holes

...Tears of a Tiger By Sharon Draper The conflict I can make a prediction about is that Andrew Jackson will probably do something bad to himself. Because when Robert Washington dies, Andrew feels awful. He wishes he was the one who burned to death. Andrew might even kill himself, because he feels so bad. Or he might hurt someone else or try to blame it on B.J., Tyrone, or maybe even on Robert One event that has surprised me in the story is that Keisha has stayed with Andy through thick and thin. She let him cry on her shoulder. And he said she’s the only one he feels comfortable around. Also that she is trying to stop thinking that he should’ve died. She also encourages Andy to think on the brighter side of his life. She even went everywhere with him to Rob’s funeral, the hospital and also the trial. Keisha’s also his best friend. I’ve read another book like this called “Unbroken.” It’s about this girl that lived a long time ago. Her mother dies, and she had a hard time getting over it. Andy is just like the girl. He’s trying to get over Rob dying, but he just can’t. He got mad at Keisha for no apparent reason, at talent show. The girl in “Unbroken” gets over her mother dying, little by little, but she’s still sad sometimes. But instead of doing what the girl did, Andy got worse and worse. Andy is still in his journey with trying to get over Rob dying. The symbolism of the title is that as strong and brave tigers are, they still cry sometimes. A new...

Holes - a Novel Study

...The novel “Holes” is a fictitious tale, with mystery, comedy, and adventure. “Holes” was written in 1998 in Texas by multi-award winning author Louis Sachar. Sachar was born March 20, 1954 in New York. He developed a love for reading in high school. He entered college and studied law. He needed to pick up a course, so he signed on to be a teacher’s aide. It became his favorite class (his first book mirrored his life as a teacher’s aide – “Louis the Yard”). Sachar practiced law until 1981 and decided to devote his time to writing. “Holes” is his most popular novel to date selling over 8 million copies worldwide and it had been made into a major motion picture by Disney. Sachar currently resides in Austin, Texas with his wife Carla and daughter Sherre. He continues to write daily focusing on stories for children and young adults. The main character is Stanley Yelnats IV (his last name spelled in reverse is his first name). There were many male Yelnats named Stanley for this reason. Stanley is overweight, bullied, has low self-esteem and no friends. He was cursed with bad luck (as all Yelnats have been for 125 years) because of his “no-good dirty rotten-pig-stealing” great-great grandfather who failed to follow instructions by Madame Zeroni. He never did steal a pig but was “cursed” with bad luck along with future Yelnat generations for disobeying Madame Zeroni. Stanley misses the school bus (a school mate put his books in the toilet), so he had to walk home...
