WIRELESS SENSOR NETWORK, METHOD AND SYSTEM FOR ADJUSTING BEHAVIORS OF WIRELESS SENSOR NODES IN WIRELESS SENSOR NETWORK

摘要

A method and a system for adjusting behaviors of wireless sensor nodes in a wireless sensor network, and a wireless sensor network are provided. The method comprises: initializing wireless sensor nodes in the wireless sensor network, in which each of a node role queue and a high energy device queue of the node is initialized to be empty; for a high energy device in the wireless sensor network, computing a node role of each surrounding wireless sensor node, broadcasting a message including the node role of each surrounding wireless sensor node and an identifier of the high energy device; for each wireless sensor node, receiving the message broadcast by the high energy device, updating the node role queue and the high energy device queue according to the message, and adjusting a behavior thereof according to the updated node role queue.

1. A method for adjusting behaviors of nodes in a wireless sensor network, comprising:
A: initializing wireless sensor nodes in the wireless sensor network, in which each of the wireless sensor nodes has a node role queue and a high energy device role queue, and each of the node role queue and the high energy device queue is defined to have no more than two elements and initialized to be empty; B: for a high energy device in the wireless sensor network, computing a node role of each surrounding wireless sensor node, in which the node role is one of a source node, a forwarding node and an affected node; C: for the high energy device, broadcasting a message including the node role of each surrounding wireless sensor node and an identifier of the high energy device; D: for each wireless sensor node, receiving the message broadcast by the high energy device and updating the node role queue and the high energy device queue according to the message; and E: for each wireless sensor node, adjusting a behavior thereof according to the updated node role queue.
