When designing a sensor network using "TDMA" (Time Division Multiple Access) for channel access, what problem does it solve compared to contention-based protocols (like CSMA)?
Correct! Well done.
Incorrect.
The correct answer is A) TDMA assigns each node a specific time slot to transmit, eliminating collisions and providing deterministic, predictable access to the shared medium, at the cost of requiring tight time synchronization across nodes
Correct Answer
TDMA assigns each node a specific time slot to transmit, eliminating collisions and providing deterministic, predictable access to the shared medium, at the cost of requiring tight time synchronization across nodes
Unlike CSMA, where nodes contend for the channel and may experience collisions and variable delay, TDMA divides time into slots assigned to specific nodes, providing deterministic, collision-free access — but requires all nodes to maintain synchronized clocks, which itself is a non-trivial distributed systems problem.
