Title
An enhanced bandwidth reservation scheme based on road topology information for QoS sensitive multimedia wireless cellular networks
Abstract
In this paper, a distributed Predictive Bandwidth Reservation scheme based on Road Topology Information (PBR-RTI), and Call Admission Control (CAC) algorithms are proposed. The goal is to reduce the Handoff Call Dropping Probability (HCDP), New Call Blocking Probability (NCBP) and to improve the bandwidth utilization. In the PRB-RTI scheme, we assume that Base Stations (BSs) are equipped with road-topology information and some Mobile Terminals (MTs) have positioning capability, while others MTs do not. The BSs estimate the probability that the MTs will enter the neighboring cells based on their factors (location, direction and speed of the MT) which are estimated by global Positioning System (GPS) and/or Received Signal Strength (RSS) and the road-topology information stored in the BSs. The BSs then compute the amount of bandwidth to be reserved, based on such estimation. Simulation results show that PRB-RTI is capable of keeping low rate for HCDP and NCBP and allocating bandwidth to new/handoff calls efficiently.
