Abstract

The invention belongs to the technical field of wireless sensor network protocols and particularly relates to a power control scheme for a wireless sensor network with chargeable nodes. The scheme is mainly used for simplifying a network structure as much as possible and simultaneously reducing node transmitting power and node degree and achieving a target of balancing and saving network energy consumption by means of an modified local shortest path tree construction method according to local topology knowledge of various nodes during generating of a simplified topology structure through power control in a wireless sensor network.

Description

technical field [0001] The invention belongs to the technical field of wireless sensor network protocols, and in particular relates to a power control scheme for a wireless sensor network with rechargeable nodes. This scheme is mainly used to generate a simplified topology structure through power control in a wireless sensor network. According to the local topology knowledge of each node, through the modified local shortest path tree construction method, the network structure can be simplified as much as possible, and the emission of nodes can be reduced. Power, reduce node degree, so as to achieve the goal of balancing and saving network energy consumption. Background technique [0002] In recent years, related technologies in the field of wireless multi-hop networks (wireless sensor networks, mobile Ad hoc networks, wireless mesh networks, etc.) have received extensive attention from academia and industry, and have achieved rapid development. [0003] Topology control is ...
