| Summary: | Hard handover mechanism is adopted to be used in 3GPP Long Term Evolution (3GPP LTE) in order to
reduce the complexity of the LTE network architecture. This mechanism comes with degradation in
system throughput as well as a higher system delay. This paper proposes a new handover algorithm
known as LTE Hard Handover Algorithm with Average Received Signal Reference Power (RSRP)
Constraint (LHHAARC) in order to minimize number of handovers and the system delay as well as
maximize the system throughput. An optimized system performance of the LHHAARC is evaluated and
compared with three well-known handover algorithms via computer simulation. The simulation results
show that the LHHAARC outperforms three well-known handover algorithms by having less number of
average handovers per UE per second, shorter total system delay whilst maintaining a higher total
system throughput. |
