This paper presents the analysis of CDMA cellular networks with channel sub-rating. From users’ point of view, our considered scheme gives higher priority to handoff calls over new calls by sub-rating the existing connections when handoff calls find no idle channels upon their arrivals. Therefore, it is considered that the disadvantage of the soft handoff(More)
This paper presents the modeling and performance analysis in the integrated ad hoc and cellular network systems. In the modeling of the other integrated systems [7, 10, 12, 14, 17], the handoff area was not considered. However, for mobile communications, handoff area is important, complicated and unstable area that is the boundary of cells. In our system,(More)
