چکیده

The allocation of limited resources such as links, servers, and agents to support as many as emergency call responses as possible while maintaining reasonable quality of service is a principal requirement in public safety networks. It is difficult to handle the highest priority emergency call responses for a congested period with a limited number of dedicated incoming links from commercial networks. Therefore, in this paper, we present the adaptive scheme based on a different call conversation time for an achieving efficient resource scheduling during a congested period without investing extra resources. The proposed adaptive scheduling approach improves accuracy of the network performance with the dynamic call holding time approach.

Modeling and Characterization of Traffic in Public Safety Wireless Networks

In this paper, we present statistical analysis of traffic in a deployed circuit-switched, trunked cellular wireless network used by public safety agencies. Prior analysis considered traffic from three busy hours during two days in 2001. Traffic data in this study span various time periods in 2001, 2002, and 2003. We examine the statistical distribution and autocorrelation function of call inter...

An Efficient Resource Allocation with Adaptive Rate Scheduling For WCDMA Networks

WCDMA is a spread spectrum technique that uses a unique spreading code to spread the data before transmission based on its orthogonal property. WCDMA is mainly used for 3rd generation cellular and mobile networks. In Centralized Call Admission Control (CCAC) technique, when a new call arrives into the system, it checks whether the call should be admitted or not on the basis of signal to interfe...

Resource allocation scheme for QoS provisioning in microcellular networks carrying multimedia traffic

We propose a new resource allocation scheme based on the concept of resource reservation and resource renegotiation. The new scheme is aimed at improving performance with regard to new call blocking rate, handoff dropping rate, forced call termination rate, and average bandwidth use. We compare our scheme with other schemes. The performance is evaluated by using simulation. Copyright  2001 Joh...
