Problems solved by technology

Frequent data forwarding will lead to rapid energy consumption of nodes in the network, shorten the life cycle of nodes, and eventually "death" due to exhaustion of node energy
"Dead" nodes are often on links with large data throughput. Once a node "dead" will cause the link to break, and eventually lead to a decline in network communication quality

Embodiment

[0017] This embodiment provides an implementation method for extending the life cycle of a multi-hop self-organizing network. In the method, the data packets forwarded in the network should include energy value information of the forwarding node. When the next hop node of the forwarding node receives the data packet, the energy value of the previous hop node is extracted from it, and the energy list of its neighbor nodes is updated. Once the energy value is less than 10%, the previous hop node will be deleted from the routing table, and it will not be selected as the next hop node for later data forwarding. When forwarding data, the node also needs to select the corresponding forwarding method and whether to forward according to its own energy value. When the node's own energy value is greater than 30%, it will forward in the normal way, and select the next hop node according to the routing table; When it is less than 30% but greater than 10%, the circular area search method i...

Abstract

The invention discloses a realization method for prolonging a life cycle of a wireless multihop self-organizing network, and the method is characterized in that the multihop self-organizing network is provided with an energy threshold value, and an energy value of each node is encapsulated in the data when data is transmitted between every two nodes; after the current node receives the data transmitted by the previous hop of node, the energy value of the previous hop of node is extracted from the data and recorded, and the energy value of the current node is used for replacement after the extraction is completed; an energy list of a neighbor node is maintained by each node in the multihop self-organizing network, and the list consists of two parts: one part is the node name in a single-hop distance and the energy value of the corresponding node, the energy list of the neighbor node is used for recording the energy value of the neighbor node, and if the energy of the neighbor node is smaller than the threshold value, the energy of the neighbor node is deleted from a route list; and when the node receives the data transmitted by the previous hop of node, the data forwarding way and whether the data is forwarded or not are elected according to the own energy value. The node energy consumption inside the network can be balanced, the communication quality of the network is improved, and the life cycle of the network is prolonged.

Description

technical field [0001] The invention relates to a realization method of prolonging the life cycle of a network, in particular to a realization method of prolonging the life cycle of a wireless multi-hop self-organizing network. Background technique [0002] Wireless multi-hop ad hoc networks have strong networking flexibility. Since there is no need for a central access node, it is especially suitable for scenarios that lack central facilities such as battlefields, rescue and disaster relief, and large-scale event sites to achieve rapid networking. At present, IEEE 802.11b technology and IEEE 802.11a / 802.11g technology are mostly used to build wireless multi-hop ad hoc networks, which have high data transmission bandwidth. [0003] But the network itself has certain flaws. Since the network does not have a central access node, data transmission is achieved through the cooperation of nodes in the network, and high-speed data transmission consumes a lot of energy for nodes. ...
