초록
This paper proposes an efficient wireless resource management scheme using a Differential Received Signal Strength Indicator (DRSSI) in soft handoff. DRSSI is the differential value of RSSIs, and can be used to monitor the movement of a Mobile Node (MN). For example, the DRSSI has a bigger value or changes its sign (+, -) if the MN changes its movement speed or direction. A base station can determine the priority of a MN and can acknowledge the movement direction of a MN with these features. By using the priority and movement direction of a MN, we can reduce the handoff blocking probability by reducing the unnecessary usage of wireless resource, which can be analyzed by numerical analysis. © Springer-Verlag Berlin Heidelberg 2006.
