To use Whatsapp, users only need to install it to their phone. Whatsapp gets configured on the user’s phone number rather than using any email id. When installed, Whatsapp communicates to its main server and compares the contacts in user’s phone. It automatically adds the people who are already using Whatsapp to the ‘Contact List’ of the user. It is a faster way to send messages to people. Whatsapp also allows users to form a group and chat, known as...

5. Suppose that are to design a wireless network with the following constraints and properties: • Cells are arranged in a conventional hexagonal layout, with equal sized hexagons. • Each cell has an area of 1 km • The number of cells per frequency-reuse cluster may be N = 1,3, 4,7 or 12. • The path-loss exponent is a = 3.5. • The minimum acceptable SIR is 11 dB. • There are 144 available channels (i.e., 144 calls can be...

LinkedOUT is a new social network. Every pair of LinkedOUT users is either acquainted or not acquainted with each other. Two users u1 and u2 are approachable if there exists a sequence of users starting with u1 and ending with u2 where each adjacent pair of users in the sequence are acquainted. New user Weff Jeiner has just signed up for LinkedOUT and is not acquainted with anyone. Given a list of all pairs of users that are acquainted on...

3. Your friend has written a new phone app that allows users to hold a finger on the screen and reports their stress level on a 0 (no stress) to 10 (maximum stress!) continuous scale. Based on millions of trials, a model has been proposed for human stress levels: c.(10 - ), f(3) = 3 0<x< 10 else a. What value must c be for this function to serve as a probability density function? b. What is the average stress...

In a study of 420,037 cell phone users, 161 subjects developed brain cancer. Test the claim that cell phone users develop brain cancer at a rate that is different from the rate of 0.0340% for people who do not use cell phones. Because this issue has such great importance, use a 0.005 significance level. Use this information to answer the following questions. a. Which of the following is the hypothesis test to be conducted? O A. Ho:p> 0.00034 OB. Ho:...

Question #3 (20 points): The phone lines to a rental car company are occupied 30% of the time. Assume that the events that the lines are busy on successive calls are independent. If 10 calls are placed to the rental company () What is the probability that the lines are busy for exactly 3 calls? () Caiculate the probability that at least one call gets through. (iii) What is the expected number of calls for which all lines are busy?

Suppose that multiple users share a 1 Mbps link. Each user has a data rate of 200 b) kbps when "active", and each user is active 10% of the time. When circuit switching is used to allocate resources on the shared link, how (2) (i) many users can be supported? When packet switching is used and the total number of users is 20, what is (ii) the probability that more than 5 users are active simultaneously? (3) What are the...
