RISK FACTOR DETOUR MULTI-PATH ROUTING SCHEME BASED ON DEFCON IN WIRELESS MULTIMEDIA SENSOR NETWORKS

摘要

The present invention relates to a defense readiness condition (DEFCON) based risk factor detour multi-path routing scheme in a wireless multimedia sensor network environment, capable of improving the life time of a sensor network by reducing the concentration of data and query in a specific node by dispersing the data and capable of providing data security and enabling data to detour around a risk area when the data passes through the corresponding area by setting a defense readiness condition in accordance with the movement of the risk factor in a data transmission adjacent to the risk factor by executing a step of setting a defense readiness condition step in each sensor node by calculating risk degrees corresponding to the location of the risk factors; a step of setting the priority of data in a source node; a step of transmitting the priority of the data to a neighboring node; and a step of executing routing with the shortest distance when the risk degree is low by comparing the defense readiness condition step with the priority of the data in the neighboring node.
