Static Wireless Sensors and IoT Networks

In static IoT networks, the sensor nodes are deployed randomly with limited power resources which demands energy-efficient data transmission schemes. Energy-efficiency of sensor nodes can be improved by network clustering, adaptive wake-up scheduling, mobile sink deployment, and adaptive sampling rate techniques. Design and development of cooperative data transmission models is an emerging area that can help overcome the limitations of conventional methods.

In time-varying IoT networks such as vehicular networks, where the nodes are mobile, require a completely different approach for efficient data transmission. Cooperative data transmission models with low-latency and high-reliability are becoming a necessity in such time-varying IoT networks.
