Problems solved by technology

SEAD maintains the routing path by extending the current routing during the Sink movement process, which causes serious end-to-end delay
And such frequent routing updates to mWSNs will lead to too much battery power consumption, and the communication overhead required to maintain routing will reduce the ability of the protocol to maximize the network lifetime.

Embodiment 1

[0029] The steps of the routing restoration method of the present invention are as follows: figure 1 As shown, the specific steps are as follows:

[0030] (1) figure 1 The routing map update phase in . Assume that there are n paths from the source node collection to the Sink, and the jth path is p j, j ∈ 1, 2, ..., n. for p j The k-th node on , stands for p j The mth link on . is p j set of nodes on . Each node v in the network has a neighbor table that stores information (such as remaining energy, energy consumption, delay, etc.) information task sheet. Once v receives a neighbor v nb , it will register its information in the neighbor table. represents a node The set of nodes in the neighbor table, similarly yes The set of neighbor nodes of each node in . N(v S ) represents the neighbor list set of adjacent nodes stored in Sink, by figure 2 It can be seen that N 1 ( v j ...

Abstract

The invention discloses a route recovery method and a recovery protocol for a mobile Sink wireless sensor network. The method and the protocol are characterized in that: when the location of a mobile Sink is changed to disconnect a path of the mobile Sink wireless sensor network, current information may be collected to update a route map, and path coding is performed; an optimal alternative path is selected by adopting an immune orthogonal learning particle swarm optimization algorithm to perform route recovery; and a network system is maintained by adopting the protocol based on the immune orthogonal learning particle swarm optimization algorithm. The immune orthogonal learning particle swarm optimization algorithm has the characteristics of relatively higher global searching capability, relatively higher solution accuracy, high rate of convergence and the like. By the method and the protocol, the route maintenance capability of the mobile Sink wireless sensor networks is improved, the maximum transmission success rate is realized by utilizing the shortest transmission path, network throughput is improved, and the time to live of the network is prolonged.

Description

technical field [0001] The present invention relates to a routing restoration method and a restoration protocol of a mobile sink wireless sensor network, in particular to the improvement of a routing method of a wireless sensor network, specifically a local routing restoration mechanism based on a swarm intelligence algorithm to find the optimal Routing recovery method and recovery protocol for mobile sink wireless sensor networks with alternative paths. Background technique [0002] The development of handheld devices such as 3G mobile phones and PDAs has led to an increasing number of applications for mobile sink wireless sensor networks (mWSNs). Compared with static wireless sensor networks (wireless sensor networks, WSNs), mWSNs have obvious advantages in terms of efficient use of energy, tracking of moving targets, network life cycle, and network connectivity. In these applications, since the Sink node often moves to a new location and the link is interrupted, its rout...
