Embodiment 1

[0051] 6LoWPAN is a low-speed wireless personal area network standard based on IPv6. 6LoWPAN is called a WPAN network with an IPV6-based protocol.

[0052] Such as figure 1 As shown, based on the dynamic construction of the load balancing routing coverage tree to achieve the maximum coverage of the 6LoWPAN wireless sensor node load balancing implementation method:

[0053] Step 1 Set up a 6LoWPAN sensing node.

[0054] Step 1.1 Use the square of the ratio of the remaining energy of a 6LoWPAN node to the forwarding distance to represent the weight of a one-hop forwarding path between an IPv6 parent node and a child node.

[0055] Step 1.2 Define when S i When working as a 6LoWPAN sensing node, the candidate IPv6 parent node S rj ∈ Q rt (S i )’s forward forward probability is defined as:

[0056]

[0057] where e rj (τ') means node S at time τ' rj the remaining energy; e k (τ') means to divide node S at τ' time rj The remaining energy of a certain node outside; α re...

Embodiment

[0080] 1. Experimental system and process

[0081] In a 100m×100m wireless sensor network monitoring area, 64 information points are randomly deployed, and 50-500 sensor nodes are arranged. The perception range of each node is 17.675m. All sensor nodes are arranged randomly. Each experimental situation was simulated 30 times. The problem of wireless sensor network sensor node coverage: the cost of deploying nodes (minimum number of activated nodes) is the lowest so that all information points are covered. If there are redundant sensor nodes in the coverage area, turn it off and let it go to sleep; if there is an information point that is not covered due to the energy depletion of a certain sensor node, you can wake up some dormant nodes to cover this information point.

[0082] The purpose of the probabilistic load balancing (PLB) scheme is to achieve load balancing by adjusting the forwarding probability. Consider any node S in the K layer (that is, the number of hops = K...

Abstract

The invention discloses an IPv6 wireless sensor node load balancing implementation method based on 6LoWPAN. The method comprises: the step 1, setting a 6LoWPAN sensing node; the step 2, calculating the forwarding probability of a 6LoWPAN relay node; and the step 3, constructing a dynamic coverage tree. According to the 6LoWPAN wireless sensor node load balancing implementation method keeping the maximum connection of the IPv6 network, the maximum coverage is achieved under an IPv6 protocol and the connectivity between each node, and a base station is kept by dynamically constructing a load balance routing coverage tree.

Description

technical field [0001] The invention belongs to the field of load balancing of wireless sensor nodes, and more specifically relates to a method for realizing load balancing of IPv6 wireless sensor nodes based on 6LoWPAN. Background technique [0002] With the development of the economy and the continuous popularization of the network, the problems of network address resources and energy consumption continue to intensify. In order to solve the problem of serious energy waste, this paper proposes a load-balanced covering tree algorithm that maintains the maximum connection under the IPv6 protocol. [0003] The biggest problem with IPv4 is that the network address resources are limited, which seriously restricts the application and development of the Internet. The use of IPv6 can not only solve the problem of the number of network address resources, but also solve the obstacle of connecting various access devices to the Internet. Combined with the above, the load balancing im...
