Problems solved by technology

The design of traditional network routing protocols is mainly to avoid network congestion, maintain network connectivity and high-quality network services. Static wireless sensor network routing does not consider the mobility of nodes, and the nodes supported by the mobile Ad hoc network protocol do not have energy constraints. limit

Embodiment Construction

[0057] The present invention is a method that supports mobile nodes and can effectively prolong the survival time of mobile sensor networks. The model of the mobile nodes in the present invention is a node with extremely slow moving speed, and at the same time, the energy of the mobile nodes is considered sufficient.

[0058] The present invention will be described in more detail according to the drawings and embodiments below.

[0059] Such as figure 1 As shown, first sprinkle some movable nodes to the area to be detected. Each node obtains its own geographical location information through GPS. And build a mobile sensor network.

[0060] 1. The sown nodes form a clustered network

[0061] (1) Select the cluster head

[0062] Each sensor node randomly chooses a value between 0-1. If the selected value is less than a certain threshold, this node becomes the cluster head node. Once the cluster head node is selected, it will not change.

[0063] (2) Create a cluster

Abstract

The invention discloses a routing method for supporting a random moving mobile sensing network. By using a clustered routing algorithm, a cluster head is selected and is not changed after being changed. The position of each node is determined through a global position system (GPS), the radius of each node is monitored, the sensing range of each node is calculated, overlapped nodes within the sensing range are determined as spare cluster head nodes, and when energy of cluster head nodes is reduced to be at a preset threshold value, the cluster head nodes transmit information to notify the spare cluster head nodes to work instead of the cluster head nodes, an open shortest path protocol is adopted in a stable transmission stage, and loads can be effectively balanced. When a mobile node enters a sensing area of the mobile sensor network, the geographical position, the moving speed and the moving direction information are transmitted in a flooding mode, and a cluster which the moving node is added into is determined according to a score value calculated by the cluster head.
