METHOD FOR JOINING MOBILE NODE IN WIRELESS NETWORK USING HYSTERESIS

摘要

PURPOSE: A network subscribing method of a mobile node using the hysteresis characteristic of a mobile network is provided to remove repetitive of subscription or withdrawal of network. CONSTITUTION: It is determined whether a mobile node is moved from a red zone to a yellow zone(S1). If so, a green zone subscription threshold point of a wireless network is dynamically allocated(S7). The green zone subscription threshold point is obtained based on RSSI(Received Signal Strength Indicator).
