Power Consumption Bottlenecks in the Development of Wireless Sensors

The faster and faster the Internet of Things is, the future world is definitely the world of sensors, and the development of sensors is showing new trends. Wireless sensors have great potential for development, and the wireless sensor camp has been expanded.

The wireless sensor's component modules are packaged in a single enclosure. During operation, it will be powered by a battery or vibration generator to form a wireless sensor network node. The nodes are randomly distributed and integrated with sensors, data processing units, and communication modules. The way the organization constitutes the network. It can collect the digital signal of the device and transmit it to the wireless gateway of the monitoring center through the wireless sensor network and send it directly to the computer for analysis and processing.

Although the development potential of wireless sensors is huge, there is also a bottleneck in its development. This is the problem of sensor power consumption. Traditional wireless networks may focus on high service quality and efficient bandwidth utilization while ignoring energy consumption. However, sensor networks cannot do this, and priority should be given to the efficient use of energy.

The biggest difference between sensor networks and traditional networks is how to efficiently use energy to optimize the network life cycle. For most sensor nodes, the overall energy consumption profile is consistent. The energy consumption of the communication module is higher than the energy consumption of the sensor module and the processor module. When the communication module is in sleep, the energy consumption is smaller than when sending and receiving data.

For this unique sensor network characteristic, the traditional way of replacing the battery to supplement energy is not realistic, so it can only save energy consumption from the hardware and software aspects of the wireless sensor network. Such as to improve the efficiency of battery energy use, reduce energy consumption when the sensor is working, there is a power-aware protocol stack, cross-layer optimization, topology control algorithms. Of course, these real implementations will take time, but once the power bottleneck is resolved, wireless sensor development will change.
