Queue Modeling of Handoff Calls with Sub Rating in Wireless Cellular Networks

چکیده
In wireless mobile communication the channel allocation and quality of service are the major factors and important issues to decide the system performance. Call dropping and handoff is a key element in wireless cellular networks in order to provide Quality of Service (QOS) to the users and to support user’s mobility. From the user’s point of view, the service of a handoff request is more important as the forced termination of an ongoing call is more annoying than the blocking of new calls. Therefore, in order to support QOS to the users we present two models, we give the priority to handoff calls with reserving some channels in model I and sub rating existing calls for new voice calls in model II. Then we calculate the blocking probability of new calls and dropping probabilities of handoff calls.

Adaptive call admission control and resource allocation in multi server wireless/cellular network
The ever increasing demand of the subscribers has put pressure on the capacity of wireless networks around the world. To utilize the scare resources, in the present paper we propose an optimal allocation scheme for an integrated wireless/cellular model with handoff priority and handoff guarantee services. The suggested algorithm optimally allocates the resources in each cell and dynamically adj...
متن کاملAnalytical Modeling of a Dynamic Handoff Scheme in Mobile Wireless Networks
In wireless networks, terminating handoff calls is generally more objectionable than blocking new calls. The Guard Channel Scheme (GCS) and Handoff Queueing Scheme (HQS) are the popular and practical strategies to prioritize handoff calls. A key issue when giving handoff calls the higher priority is how to achieve a tradeoff among the handoff call blocking probability, new call blocking probabi...
متن کاملComputational analysis of (MAP1, MAP2)/(PH1, PH2)/N queues with finite buffer in wireless cellular networks
This paper studies a queueing model with the finite buffer of capacity K in wireless cellular networks, which has two types of arriving calls—handoff and originating calls, both of which follow the Markov arriving process with different rates. The channel holding times of the two types of calls follow different phase-type distributions. Firstly, the joint distribution of two queue lengths is de...
متن کاملModeling and analysis of queuing handoff calls in single and two-tier cellular networks
Two-tier cellular networks consist of a group of contiguous microcells overlaid by a macrocell. This design provides an enhanced use of the networks’ resources for both high and low speed users because of the availability of additional channels. However, this causes an increase in the number of handoffs between cells due to having smaller cell sizes in the microcell tier. Since, handoff call bl...
متن کاملA Preemptive Priority Handoff Scheme in Integrated Voice and Data Cellular Mobile Systems
In this paper, we propose a preemptive priority handoff scheme for integrated voice/data cellular mobile systems. In our scheme, calls are divided into three different classes: handoff voice calls, originating voice calls, and data calls. In each cell of the system there is a queue only for data calls. Priority is given to handoff voice calls over the other two kinds of calls. That is, the righ...
