Modeling and analysis of queuing handoff calls in single and two-tier cellular networks

Comparing a class of dynamic model-based reinforcement learning schemes for handoff prioritization in mobile communication networks

“…For this reason, the determination of an optimal policy is critical to maintain a balance between the system utilization and the handoff failure probability. Other techniques allow queueing with the guard channel approach of the new connection requests and/or handoff requests (Chang, Su, & Chiang, 1994;Hong & Rappaport, 1986;Salih & Fidanboylu, 2006;Tekinay & Jabbari, 1991) until a channel becomes available. If no channel becomes free before a maximum allowable delay, the request is eventually dropped.…”

Minimizing the cost of two-tier cellular network with queuing handoff calls in microcell using genetic algorithm

“…The mean queue time depends on mean cell dwelling time and maximum crossover distance m, over the overlapping zone between two cells. Mean queen time is shown as [16].…”

Smart-HOP: A Reliable Handoff Mechanism for Mobile Wireless Sensor Networks

“…In [9], some channels are exclusively allocated to handoff calls, also known as guard channels. In [8], a queuing strategy has been applied to delay the handoff calls until a channel becomes available. Contrary to these resourceful systems, WSNs have constrained energy resources and simple single-channel radios, which require different solutions.…”
