Fuzzy Based Buffer Management in Wireless Multimedia Networks
This paper presents a fuzzy based buffer management scheme that performs buffer allocation and packet dropping for wireless multimedia networks in the context of future generation cellular networks. In this scheme, buffers are allocated to requesting application by using buffer allocation factor and packets are dropped for an application by using dropping factor. A buffer allocation factor for requesting application is computed adaptively based on three fuzzy parameters of an application, namely, priority, rate of flow and packet size. Whenever a burst of data arrives and the buffers are insufficient, the scheme computes a dropping factor that uses three fuzzy parameters, namely, application priority, queue length and packet size.
