Energy adaptive charging method combined with geographical location routing in WRSNs

Abstract

The invention discloses an energy adaptive charging method combined with geographical location routing in WRSNs. The energy adaptive charging method is used for ensuring that all nodes in the networks can be supplemented with electricity in time to balance network energy and prolong the network life cycle. Charging characteristics of a charger and geographical location information of the nodes are combined to design a routing protocol, and on the basis of determining the algorithm routing protocol, according to the actual energy distribution situation in the networks, the nodes with larger energy consumption are supplemented with more energy to balance the network energy by adjusting the moving speed of the charger. Therefore, the network service life can be effectively prolonged, sufficient rest of the charger can be ensured, and the charging efficiency is improved.

Description

technical field [0001] The invention belongs to the wireless sensor network charging technology, in particular, the invention relates to a method of using wireless charging technology to supplement energy for nodes in the network and dynamically adjust the charging amount of the charger according to the energy consumption of the nodes to achieve network energy balance and prolong the life of the network Methods. Background technique [0002] WRSNs is the abbreviation of wireless rechargeable sensor network, which includes one or more mobile chargers, which can transmit energy to the nodes in the network through wireless charging, so as to supplement the energy of nodes, and solve the problem of power consumption in traditional sensor networks. The problem of limited and difficult battery replacement greatly prolongs the life cycle of the network. At present, the relevant research literature on the charging algorithm in WRSNs is as follows: [0003] 1. Constantinos Marios A...

AI Technical Summary

Problems solved by technology

The disadvantage is that in this algorithm, after the deployment is completed, the charger is limited to certain locations, and only considers the energy supplement to the node within one charging cycle, while ignoring the problem of network sustainability

[0009] 1. Without joint actual routing, consider the actual energy distribution of nodes in the network, that is, simply assume that the energy consumption of nodes is equal or a random value;

[0010] 2. Only consider the charging strategy within one charging cycle without considering the adjustment of the charging strategy that may be required due to energy changes;

[0011] 3. Does not consider the energy and time cost of charger movement;

[0012] 4. The calculation is complex and not suitable for large-scale networks
