CTBS: Cost-effective target bs selection scheme in IEEE 802.16e networks

Modern wireless networks require wide bandwidth and high-speed mobility, and IEEE 802.16e is considered to be a technology capable of meeting such requirements. One of the most important issues with IEEE 802.16e is for the handover technology to provide seamless high capacity data services at a high speed rate. Data transmission to the terminal device is interrupted while scanning is performed for the handover procedure. Naturally, prolonged scanning undermines the network’s performance. In order to resolve this problem, we propose a scheme for reducing the number of base stations to be scanned by performing negotiation prior to scanning. The proposed approach’s performance shall be evaluated by analyzing the total time required for scanning and comparing it to the conventional method, which is the IEEE 802.16e standard.
