The objective of this lab is to gain a better understanding of how to design a network with
multiple users. The network has many variables that have to be taken int
Lab Report 2
In this lab I designed a few different scenarios that would help demonstrate the
characteristics of hubs and switches in network systems. The scenarios consisted of
Lab Report 1
In this lab, I designed networks in the OPNET software that we used to simulate different
scenarios. These simulations allowed me to determined that characteristics of a
Problem 1: In the Hardware Lab, we touched some sensor network basics. Can you
check http:/www.memsic.com to find out what types of devices (from Crossbow Inc.) may

Problem 1: Explain the mote (TelosB or Mica 2) hardware architecture. Check the data
sheets in Xbow.com to find out how much flash memory and how far the wireless distance
is (for TelosB or Mica2).
Problem 1: What is Nyquist Theorem?
The Nyquist-Shannon sampling theorem is a very important part of signal
processing. Named after Harry Nyquist and Claude Shannon, this theorem is primarily
used to convert
Problem 1: Compare TCP and UDP (in terms of pros and cons).
