One of the key challenges in integrated wireless and mobile networks is to
efficiently support multi-class services as each type of services has distinct
characteristics and quality of service (QoS) requirements. Problems in handoff
algorithm or its parameters may lead into call drops with a direct effect on user
satisfaction. This is particularly critical for 3G systems, where high data rate
users will be prime candidates for being dropped. Unnecessary handoff leads
to degraded call quality and waste of capacity in signaling. Since the cell-size
is constantly decreasing, therefore it is important to devise a handoff algorithm
which identify users with different mobility and data rate characteristics and
maximize the utilization of network infrastructure. A Multiple Queuing
System for handoff in integrated real-time and non-real time service with
priority reservation and preemptive priority handoff scheme is being analyzed
which categorizes the service calls into four different types, namely, real time
and non-real time service originating calls, and real-time and non-real-time
handoff request calls and divide the channels among these four types of
services according to their priorities. The system is modeled using a
multidimensional Markov chain and a numerical analysis is presented to
estimate blocking probabilities of originating calls, forced termination
probability, and average transmission delay. Our results show that the
predictions of the analytical model are in very good agreement with simulation
results. Scheme significantly reduces the forced termination probability of
real-time service calls. The probability of packet loss of non real-time
transmission is shown to be negligibly small, as a non-real-time service
handoff request in waiting can be transferred from the queue of the current
base station to another one. |
