Problems solved by technology

However, most traditional routing protocols are aimed at static sensor networks, and the existence of mobility will bring additional overhead and energy consumption to the network. Therefore, it is necessary to balance the two performance indicators of energy consumption and data transmission success rate to realize the optimization of routing protocols. promote

Embodiment

[0039] This embodiment provides a method for implementing an energy-saving routing protocol applicable to a mobile wireless sensor network, including the following steps:

[0040] Step A: Network initialization, the sink node broadcasts a HELLO message to the entire network;

[0041] Furthermore, the network initialization phase defines the operation cycle of the routing protocol. This operation cycle includes the establishment phase and the steady state phase. The state stage is realized. Among them, the establishment phase includes a pre-establishment process, which is composed of an invalid cluster head election process, that is, if the number of cluster head nodes currently elected is small (for example, less than 3% of the total number of nodes), it is an invalid election; According to the number of chain head nodes N c1 divided into N c1 frame.

[0042] Step B: The establishment of the network node cluster chain structure. First, each node in the network independentl...

Abstract

The invention provides an energy-saving routing protocol realization method suitable for the mobile wireless sensor network. The method comprises the following steps of A) network initialization; B) establishment of a cluster-chain structure of network nodes; C) data transmission and gathering; and D) mobile management and cluster member updating. According to the method, the cluster-chain graded structure formed by the sensing nodes and a qualification decision mechanism of cluster head nodes are used to reduce network energy consumption caused by data transmission, the energy effectiveness is improved, service time of the network is prolonged, a periodical member information updating mechanism of mobile nodes is used for mobile management, it is ensured that data packets are transmitted successfully, and the network performance is improved.

Description

technical field [0001] The invention relates to the technical field of mobile wireless communication, in particular to an energy-saving routing protocol suitable for mobile wireless sensor networks that reduces energy consumption and ensures data delivery based on a cluster chain structure formed by network nodes and a mobility management mechanism. Background technique [0002] With the rapid development of mobile Internet technology, dynamic information collection and remote control based on various mobile terminals such as wearable devices have shown great vitality on Internet of Things technology platforms such as smart homes. Using wearable devices as the medium of information collection is also in line with the definition and expectation of "people-centric" data in the Internet of Things. Typical applications are various wearable health monitoring devices. In essence, the Internet of Things can be abstracted into a wireless sensor network model, which consists of a ser...
