Question
1. We learned that an 802.11 network can choose to operate using any of the 11 different available channels (frequency bands). Consider the figure shown in below. Can you assign channels to nodes such that the wireless network achieves the same throughput as in the wired case? (Note: you may assume that each node has two interfaces, with each interface having a different channel). 2. Suppose Alice and Bob are interacting via a TCP session, and that Trudy is on a broadcast segment where traffic passes between Alice and Bob. a.) In 40 words or less, describe how Trudy can masquerade as Alice and hijack the session. b.) In 40 words or less, why will Bob quickly drop the TCP session with the basic approach?
Explanation / Answer
1) 802.11 network can choose to operate any of the 11 different available channels yes we can assign channels
to nodes by defining in such a way that it will assign from a very definite way to assit the bandwidth.
2)bob and alice are interacting with a tcp session it will quickly drop the tcp session with basic approach
