Wireless sensor network through which ways to achieve?

How is the wireless sensor network implemented? There are many ways to achieve this.

1, the traditional communication protocol Flooding. The information is sent to neighboring nodes in the form of broadcast, and the node that received the information continues to broadcast in the same manner until the message is sent to the destination.

Advantages: Easy to use, no maintenance required.

Disadvantages: A node may experience the phenomenon of receiving multiple identical messages, and two nodes that are close to each other may detect almost the same data.

2, GossipingGossiping. Randomly select a nearby node, send a message to it, and if the child node has received the message, return the message.

Advantages: Improved Flooding's flaws.

Disadvantages: There is no solution to the overlap problem and the transmission time is extended.

3, adaptive communication protocol SPINSPIN. The node negotiates with other nodes before transmitting data to ensure that the transmitted information is useful. The SPIN node communicates with three types of messages. When the SPIN node has data to share, it announces it by sending an ADV message. The SPIN protocol is divided into four types: SPIN-PP, SPIN-BC, SPIN-EC and SPIN-RL.

4. Data-centric routing protocol directeddiffusion. The sensor node describes its data with multiple attributes, and other nodes use these attributes to express their interest, generating gradients that direct the data broadcast, and the data propagates to each node based on this gradient.

5. LEACH agreement. In the class preparation phase, the LEACH protocol randomly selects one sensor node as the class head node, and the randomness ensures that the high energy costs of data transmission between the class head and the base station are evenly distributed to all sensor nodes.
