Question

Which is not a variant of s-mac timeout mac (tmac) dynamic sensor mac (dsmac) input-output mac (iomac) data gathering (dmac)?

Answer 1

The correct answer could be the third option - Input-Output MAC (IOMAC).

Sensor Media Access Control or the S-MAC is a network protocol that is used for sensor networks. These Sensor networks sensor nodes that are tiny, wireless communicating computers sensor nodes that are deployed in huge numbers so that these networks can work independently and monitor their surroundings. These network sensors are designed for group work when their energy reserves are depleted.

The S-MAC protocol has been studied extensively and several subsequent protocols have been made that include many suggestions for the improvement of its performance. A few examples include - the Timeout MAC (T-MAC), the Dynamic Sensor-MAC (DS-MAC), Berkeley Media Access Control (B-MAC), etc.
