Embodiment Construction

[0047] An improved AODV routing method based on terminal energy perception proposed by the present invention will be further described below in conjunction with the accompanying drawings.

[0048] according to figure 1 The business process of the virtual terminal system is shown, and the schematic diagram of the routing optimization model of the collaborative communication network on the terminal side of the virtual terminal system is obtained, as shown in figure 2 shown.

[0049] First, according to the traditional tree routing algorithm, a tree topology network is established and a unique network address is set for each node in the cooperative communication network in the terminal side scenario of the virtual terminal system. Assume that the depth of the parent node X in the tree topology network is d, and the address is A p , if the nth node is added to the parent node as a simplified function device - RFD, which can only receive and send data, without routing and forwar...

Abstract

The invention provides an improved AODV routing method based on terminal energy sensing. In the method, a flooding node range is obtained according to the depth of a source node and the depth of a destination node in a tree topology network, equipment is divided into two grades according to residual energy in the scene of terminal energy sensing and balancing, a threshold energy range is dynamically divided according to consumed time of the nodes in a flooding path, and therefore it is avoided that the path contains different position and time terminals to cause premature death and failure. The method achieves reasonable flooding and utilizing of the nodes, effectively reduces the sum number of the flooding nodes, is oriented towards the terminal side of a virtual terminal system, is very simple and easy to implement, and has a very good application prospect.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, in particular to an improved AODV routing method based on terminal energy perception. Background technique [0002] In the wireless ubiquitous network environment, the virtual terminal system integrates and manages network resources through heterogeneous network integration, and performs service integration through terminal aggregation and reconstruction, providing users with more diversified services and higher user experience quality. In the scenario of the terminal side of the virtual terminal system, the terminals communicate collaboratively to transfer and integrate system services. The system business process is as follows: figure 1 shown. In this scenario, an excellent inter-terminal routing algorithm can reduce inter-terminal communication delays, improve resource utilization on the terminal side, and provide users with high QoS guarantees. [0003] In the traditional AO...
