An assister-based clustering method in Ad Hoc network

Abstract

The invention is a clustering method based on assistance in Ad Hoc network relating the field of Ad Hoc network and clustering management in the network. The Ad Hoc network is a wireless network without infrastructure and the clustering management is a more efficient network module. Reasonable selection of the clustering head is significant for the Ad Hoc network adopting clustering structure. The invention provides a method clustering method based on assistance. The method reduces probability of the cluster node that would become network bottle neck in existing clustering method by selecting a cluster-establishing way of assistant node in the cluster for the cluster head, reducing data information process of the cluster node and saving energy of the cluster head, which is beneficial to manage the network and to improve performance of the network.

Description

technical field

[0001] The present invention relates to node management in a wireless mobile self-organizing network (also known as an Ad hoc network). Considering that the energy consumption of a cluster head node is much higher than that of an ordinary node in a cluster, an assistant node is selected for the cluster head node to share the cluster head Part of the data processing of the nodes saves the energy of the cluster head and is suitable for cluster management to avoid network bottlenecks in the Ad Hoc network. Background technique

[0002] The Ad Hoc network does not depend on any basic fixed facilities, and the communication between non-adjacent nodes requires the relay of intermediate nodes; because the nodes in the network can move arbitrarily, the network topology changes dynamically. Due to its independent networking capability, self-organization, centerlessness, dynamics, and ease of laying, the Ad Hoc network is widely used in the construction of temporary in...
