EMMM: Energy-efficient mobility management model for context-aware transactions over mobile communication

摘要

The rapid advancements in wireless technology and enhanced computing power of handheld devices, enable the users to perform transactions anywhere, anytime during roaming. Carrying out ongoing transactions during roaming is a crucial field for research in the field of mobile communication. In order to ensure a high quality of service (QoS), an energy-efficient handover process is essential for accomplishing the ongoing transaction. The performance of mobile communication is mainly deteriorated by the roaming and low battery power requirement of mobile host. Due to limited channel availability, most of the handover requests are failed. Energyefficient enhanced mobility management queuing model is proposed by combining two existing schemes GE/ GE/C/N/FCFS and scheme GE/GE/C/N/PR to strengthen the performance. In this research, EMMM scales down the dropping rate of handover transaction request (HTR) and new transaction request (NTR).The proposed model has achieved the enhancement of channel utilization along with the reduction in handover failure and low drop and blocking rate of HTR and NTR, respectively.
