Abstract: | Mobility management is the most important feature of a wireless cellular communication system. Continuation of an active call
is one of the most important quality measurements in the cellular systems. Handover makes it possible for a user to travel
between various networks or cells while having a seamless connection. This paper shows that, performance of cellular network
can be increased with proposed adaptive soft handoff algorithm, which dynamically calculates the Soft handover margin based
on the received signal strength and distance. Performance is evaluated in terms of the performance metrics active set update
rate, active set size, soft handover region and probability of outage. Simulation results show that soft handover algorithm
gives better performance with adaptive soft handoff margin compared to that of fixed soft handover margin in varied propagation
conditions. |
