The outage behavior is almostsame as that of amplify and forward technique but the
energy savings achieved at the low threshold values is
the added advantage of this system. The NS-2
experimentation has shown substantial enhancement
in the system throughput. Simulation results reveal
the tradeoff between energy consumption, latency
and throughput in S-MAC operation. The novel
aspect of this work will definitely lead towards
standards and standardization in future. This work
will be extended further for authentication and
authorization in cooperative IoT systems.
