Problems solved by technology

When the remaining energy of the neighbor node is not enough to bear the energy overhead of receiving and forwarding data packets in this data interaction, the sending node still sends data multiple times according to the established sending mechanism, resulting in waste of energy and unnecessary forwarding overhead
[0012] 2. When the remaining energy of the receiving node cannot support receiving and sending data, the sending node will think that it is unwilling to forward the data and deduct its reputation value, thereby affecting the forwarding of its da

Embodiment Construction

[0044] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings and specific examples.

[0045] 1. The specific operation of the efficient routing method based on energy information piggybacking in mobile sensor networks is as follows:

[0046] An efficient routing method based on energy information piggybacking in mobile sensor networks includes three main stages: node encounter perception, data interaction, and reputation table update, such as figure 1 shown.

[0047] Phase 1. Node encounter awareness

[0048] This phase consists of the following three steps:

[0049] Step 1: Nodes periodically broadcast Beacon messages.

[0050] When a node is temporarily in a static state, each node uses a certain transmission power and repeatedly broadcasts a Beacon message at a fixed periodicity. The Beacon message includes the node's identity and other related identification information.

[0051] Ste...

Abstract

The invention discloses an energy information piggybacking based high-efficiency routing method in a mobile sensor network. The method adopts three new mechanisms of zero-overhead information piggybacking based on a reputation table, neighbor node transmittability judgment based on residual energy and ACK (acknowledgement character) message on-demand unicast, and solves the problems that in existing related routing methods for the mobile sensor network, due to no consideration to a case that residual energy of a neighbor node is insufficient to complete data transmission and receiving, a sending node ineffectively sends data, a receiving node can cause a reputation computing error when the energy is insufficient to transmit the data, and an ACK message is flooding-transmitted in the network to cause control overhead and excessively high node energy consumption, so that control overhead in the routing process can be reduced, node energy can be saved, and a service life of the network is prolonged. The high-efficiency routing method disclosed by the invention is divided into three stages of node encountering and sensing, data interaction and reputation table updating.

Description

technical field [0001] The invention relates to a routing method for encouraging selfish nodes to cooperate in a mobile sensor network, in particular to an occasion where reputation values ​​are used to encourage and promote the cooperative behavior of selfish nodes. Background technique [0002] A mobile sensor network is a wireless sensor network in which nodes can move. With the gradual widespread application of mobile sensor networks (such as wild animal tracking, planetary detection and military applications, etc.), it has been paid more and more attention by people. The mobile sensor network is composed of multiple mobile sensor nodes. Wireless communication is used between nodes. The topology of the entire network changes dynamically. There is no complete path for communication between nodes, so the "storage-carry-forward" is adopted between nodes. " mode for data transfer. Usually, due to the relatively insufficient resources (energy or cache space) of nodes in mob...
