Abstract: 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.

Abstract: PURPOSE: A TCP performance enhancement method in a mobile IP(Internet Protocol) packet buffering mode is provided to improve TPC performance of mobile terminal flows when a mobile terminal moves to a congested base station of a new sub-network in a smooth hand-off method. CONSTITUTION: A buffer stores packets being lost in hand-off by each mobile terminal flow. A marker marks buffered packets in the buffer as priority packets. The buffer and the marker are determined. The minimum threshold and the maximum threshold are determined in an RED buffer management method. If a variable showing the average length of queue exceeds the minimum threshold, arrival packets are discarded according to probability. If the variable reaches the maximum threshold, all the arrival packets are discarded.
