AI Technical Summary

Problems solved by technology

If a node lacks awareness of the external environment, it cannot respond to the rapidly changing environment around it and adjust its strategy in a timely manner
The consequence of this is that nodes cannot adapt well to topology changes, and network performance is severely restricted

example 1

[0192] The result of Example 1 shows that after using the routing protocol selection method of the present invention, some aspects of the performance of the ad hoc network can be improved.

[0193] Simulation example 2 compares the network performance after using different routing strategies.

[0194] The three different routing strategies in simulation example 2 are:

[0195]

[0196] It can be seen from the simulation results that in Example 2, using the routing protocol selection method of TARCS1, no matter what speed the node moves, the network packet transmission rate is the largest, as shown in Figure 11 shown.

[0197] It can be seen from the simulation results that in Example 2, the order of network throughput is: TARCS1>TARCS2>TARCS3, such as Figure 12 shown.

[0198] It can be seen from the simulation results that in Example 3, regardless of the node speed, the average end-to-end delay of TARCS3 is the smallest, as Figure 13 shown.

[0199] It can be seen ...

example 2

[0200] The results of Example 2 show that different routing strategies can improve different aspects of network performance.

[0201] In actual scenarios, due to the uncertainty of the target and the complexity of the environment, the trajectory and movement of nodes will change at any time. The significance of the present invention is to allow nodes to perceive and respond to these changes, so that the network performance is affected by these changes as little as possible. The present invention provides an adaptive routing protocol selection method by using the perceived changes in topology state between nodes in the network, so that nodes can quickly adapt to changes in mobility patterns, and prevent network performance from being affected by changes in node mobility patterns. reduce.

Abstract

The invention discloses a method for selecting an adaptive routing protocol in a mobile ad-hoc network. The method includes: periodically sensing and calculating the instantaneous topology change degree of the entire network; combining the instantaneous topology change degree of the entire network with the pre-calculated Compare the threshold / interval of the topology change degree to determine the mobility model of the node; based on the preset strategy, select the corresponding routing protocol according to the mobility model of the node. The method of the present invention is suitable for complex task scenarios in highly dynamic mobile ad hoc networks; the method can judge the current movement mode of nodes in time according to the perceived topology change results, and quickly make adjustment strategies; it can realize mobile ad hoc networks Effective matching between routing protocols and mobility modes.

Description

technical field [0001] The invention relates to the field of mobile ad hoc networks, in particular to a method for selecting an adaptive routing protocol for a mobile ad hoc network. Background technique [0002] Node mobility is one of the most notable characteristics of mobile ad hoc networks. The different mobile modes of nodes lead to the differences in link connection modes between nodes in mobile ad hoc networks. Routing protocol is one of the important factors of mobile ad hoc network performance. In mobile ad hoc networks, different routing protocols are suitable for networks with different characteristics. The matching degree of node mobility and routing protocol seriously affects the performance of mobile ad hoc networks. During the life cycle of the mobile ad hoc network, no matter how the node moves, the routing protocol generally does not change. In the case of low node mobility, there is nothing wrong with this approach. However, in a highly dynamic enviro...
