VARIABLE PACKET TRANSMISSION METHOD ACCORDING TO SELECTIVE QUERIES IN WIRELESS SENSOR NETWORK

摘要

According to the present invention, the packet transmission time of a sensor node is reduced as the query is small and the length of a packet is closely related to the packet transmission time of the sensor node thus reducing energy consumption by performing a selective query to increase the time of a life than a conventional method. Additionally, the packet transmission time thereof is increased depending on the selective query and approximately 1.5% of energy is decreased in terms of energy consumption and the conventional method if the selective query is two, by which the simulation of the packet transmission depending on the selective query confirms the energy consumption of the sensor node and confirms a data success rate via the simulation when an event happens using an NS-2 simulator in order to compare of energy efficiency and the conventional method.;COPYRIGHT KIPO 2014
