  1. Game Theory

  2. Mixed Integer Programming

  3. Branch and Bound Algorithm

  4. Lagrangian Relaxation


Correct Option: A
Explanation:

Game Theory is commonly used for spectrum allocation in telecommunications networks as it allows for modeling the interactions and strategic behavior of multiple users or service providers competing for limited spectrum resources.

In the context of network resource allocation, what is the trade-off between throughput and latency?

  1. Higher Throughput Leads to Lower Latency

  2. Higher Throughput Leads to Higher Latency

  3. Latency is Independent of Throughput

  4. Throughput and Latency are Always Proportional
