Embodiment Construction

[0008] The present invention adds a strategy of node energy balance on the basis of the reliable and high-efficiency routing method of the opportunity routing algorithm, and forms a cross-layer protocol with high energy efficiency and high data forwarding efficiency.

[0009] It is assumed that each node in the network knows the ETX value of each link in the network (it can be realized by nodes spreading the ETX of adjacent links throughout the network). When data packets are forwarded, the source node takes the neighbor node whose ETX value to the destination node is smaller than the ETX value from itself to the destination node as a candidate forwarding node, and ensures that each candidate forwarding node is within the transmission radius of each other , and join the set of alternative forwarding nodes. Before forwarding, the source node arranges the priority of the candidate forwarding nodes according to the product of the ETX from the candidate forwarding node to the dest...

Abstract

The invention belongs to the technical field of a wireless sensor network protocol, which concretely relates to an energy efficiency opportunity routing protocol in a wireless sensor network. The invention modifies the traditional opportunity routing aiming at the property that the energy of the sensor network can not be regenerated, adjusts the priority level of standby forwarding nodes in the opportunity routing according to the residual energy of the forwarding nodes, reduces the priority level of nodes with lower residual energy, and enhances the priority level of transfer nodes with higher residual energy. By the adjustment of the sequence of the priority level of the forwarding nodes, the probability that the nodes with lower residual energy undertakes an actual forwarding task is reduced, so that the energy consumption of the forwarding nodes is slowed down; contrarily, the nodes with higher residual energy has larger probability to undertake the forwarding task. By applying the mechanism, the data forwarding task carries out dynamic adjustment according to the quantity of the residual energy of the nodes, so that the purpose of energy balance in the whole network is achieved.

Description

technical field [0001] The invention belongs to the technical field of wireless sensor network protocols, and in particular relates to an energy efficient opportunity routing protocol in a wireless sensor network. This method takes advantage of the fact that opportunistic routing can effectively improve network throughput, and at the same time fully considers the characteristics that the sensor network's energy cannot be regenerated, and proposes an energy-balanced opportunistic routing protocol. Background technique [0002] Wireless sensor network is an emerging technical field that integrates microelectronics technology, wireless communication technology, and computer technology that has emerged in recent years. It has very broad application prospects in the fields of environment, medical treatment, and military affairs. Its development and application will give It has a profound impact on all aspects of human life and production. Although the large-scale commercial appl...
