Designing an efficient preemptive priority based handoff queuing algorithm for wireless networks

Handoff has the prime importance in cellular wireless systems. With the development of 3G cellular communications there is a need of efficient and faster handoff algorithm with minimum delay and minimum call dropping probability. As the number of mobile user increases with the demand of both voice and multimedia data services, the demand for efficient handoff algorithms also increase. In this paper, we have focused on preemptive priority handoff scheme for voice handoff request calls with higher priority. From the performance analysis, it is observed that preemptive handoff scheme is better than non-preemptive priority handoff scheme
