Paper Abstract

The shadow cluster concept is used to estimate the future resource requirements, to reserve resources accordingly, and to admit only those calls which can be supported adequately. This paper describes the use of shadow cluster concept to allocate resources in Ad hoc networks using Cluster Head Gateway Switch Routing (CGSR) . With shadow cluster, the QoS of mobile calls can be improved by reducing the number of dropped calls during handoff, and by disallowing the establishment of new call that are highly likely to result in dropped calls later. In our work, we have used the shadow cluster concept to predict the demand by calculating the active mobile probability (AMP) of a call. Using this information, the resources are reserved in advance in the shadow area of the call. The performance results show that the shadow cluster scheme has less call drop, less call acceptance and fair bandwidth utilization.
