We study secondary spectrum sharing in narrowband cellular networks in which calls in neighboring cells need to be assigned different channels. Analysis of such networks are in general difficult due to large state spaces and lack of closed form expressions. Here we consider linear topologies and show that they lend themselves to exact analysis. We analyze four sharing policies where equilibrium distribution...
This paper investigates the optimal call admission control (CAC) policy for non-priority scheme (NPS) and reserved channel scheme (RCS) in wireless networks, respectively. Both new call and handoff call arrival processes are assumed to be Poisson processes, and the call holding times are exponentially distributed with different rate for new call and handoff calls. Admitting each call would bring a...
