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 data packets, causing the receiving node to be punished by errors, affecting network throughput
[0013] 3. The calculation of the reputation value of nodes in the network requires statistics of cooperative behavior and non-cooperative behavior, and requires the next two hop receiving nodes of the sending node to send ACK messages (located at the network layer); the control message is propagated through the network layer in a flooded manner , resulting in large network control information overhead, affecting network resource utilization and network performance

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.

The present invention proposes a high-efficiency routing method for mobile sensor networks based on energy information piggybacking. "Three new mechanisms solve the problems caused by sending nodes invalidly sending data due to the fact that the remaining energy of neighboring nodes is not considered enough to complete data transmission and reception in the existing routing methods related to mobile sensor networks, and the reputation caused by receiving nodes when the energy is not enough to forward data Calculation errors and ACK messages cause excessive control overhead and node energy consumption through flooding in the network, thereby reducing control overhead in the routing process, saving node energy, and extending network life. The high-efficiency routing method proposed by the present invention is divided into three stages during operation: node encounter perception, data interaction and reputation table update.
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...
