A Novel Approach for Queuing based Handoff for Increasing Reliablity of Mobile Communication

Call drop rate during Handoff in mobile communication degrade the performance of system. This paper describes a novel approach to increased reliability in mobile communication with reference to rate of change of reverse signal strength. Handoff available scheme which discussed in paper are inefficient to decrease call drop rate due to handoff. Call drop rate depend on channel availability and on rate of decrease of reverse signal strength. Channel availability problem can be solved by increasing frequency range in that particular cell or by dividing cell in to micro cell that's why there very few effect of call drop rate due to channel availability. Call drop rate is more affect by approach to treat decease in reverse signal strength during handoff. In available approach Handoff decision are taken based on treating handoff call and new call in that particular cell as equal (No Priority) or starting Handoff procedure by monitoring RSS continuously (Delayed Handoff) or providing separate channel for Handoff call and new call (Guard Channel Approach) or Queuing the handoff call and proving channel to handoff call by LIFO manner (Queuing base handoff).
