Abstract
This paper presents a Call Admission Control
(CAC) algorithm based fuzzy logic to maintain the quality of
service using cell breathing concept. When a new call is accepted
by a cell, its current user is generally affected due to cell
breathing. The proposed CAC algorithm accepts a new call only
if the current users in the cell are not jeopardized. Performance
evaluation is done for single-cell and multicell scenarios. In
multicell scenario dynamic assignment of users to the
neighboring cell, so called handoff, has been considered to
achieve a lower blocking probability. Handoff and new call
requests are assumed with handoff being given preference using
a reserved channel scheme. CAC for different types of services
are shown which depend upon the bandwidth requirement for
voice, data and video. Distance, arrival rate, bandwidth and nonorthogonality
factor of the signal are considered for making the
call acceptance decision. The paper demonstrates that fuzzy logic
with the cell breathing concept can be used to develop a CAC
algorithm to achieve a better performance evaluation.
