Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings and implementation examples.

[0012] The invention is a wireless sensor network random dormancy scheduling routing method for the purpose of balancing and reducing energy consumption. The main components of the present invention will be described in detail below:

[0013] Generation and maintenance of pseudo-random number sequences: The random number sequence generated by mathematical method is calculated from the given seed according to the determined algorithm. Therefore, the generated sequence does not actually satisfy complete randomness. However, the sequence generated by a well-designed random number algorithm can pass a certain degree of randomness test. This sequence of numbers is called a pseudo-random number sequence. Under the premise of the same seed, the same random number generation algorithm can repeatedly generate the same pseudo-random number sequen...

Abstract

The invention discloses a random dormancy scheduling routing method for a wireless sensor network, belonging to wireless network protocol. The method is specifically characterized in that each node maintains one pseudo-random number sequence. The number sequences are generated from seeds, randomly generated by nodes, by the same pseudo-random number generation algorithm. Then, each node determines own random dormancy time sequence arrangement in the network operation cycle according to the random number sequence. By broadcasting own seed during network initiation, the node and a hop neighbor thereof can acquire both pseudo-random number sequences through calculation so as to acquire both dormancy and awake time. When needing to send data, the node sends a data packet to the first awake node by calculating the awake time of own neighbor. The mechanism achieves the alternative working of the nodes through a random dormancy scheduling mechanism in order to reach the purpose of reducing and equalizing the energy consumption of the entire network.

Description

technical field [0001] The invention relates to wireless network communication technology, in particular to a node sleep routing method of a wireless sensor network. Background technique [0002] In recent years, related technologies in the field of wireless sensor networks have received widespread attention from academia and industry, and have achieved rapid development. [0003] Among many research directions in this field, prolonging the working life of wireless sensor network as much as possible has become one of the key issues in the design of wireless sensor network. Due to the limitation of factors such as cost and volume, the processing power, wireless bandwidth and battery capacity of wireless sensor network nodes are very limited. At the same time, the energy of nodes cannot be replenished in most cases. In order to improve the lifetime of wireless sensor networks, the energy conservation and balance of nodes in the network has become the focus of research. [0...
