“…The MQTRFHPJ scheme serves users based on the maximum queue to transmission rate ratio when a significant number of users are in the cell handoff zone. The fairness scheme used was presented in the service model in Section VI.A [8,9]. Figure. 4 the user traffic load is varied over time for 50 users.…”

“…The MQTRFHPJ algorithm aims to minimize network resource use. Hence lower level modulation schemes are applied to cell boundary users as shown in Table II [8,9], and so the data rate is lower in the handoff mode. More over, as packets are not forwarded from the IP layer to the radio layer when the radio layer buffer is full and thereby reducing the P dr , DL th of the MQTRFHPJ algorithm is lower than that for the Max CIR and PF schemes.…”

The research presented in this paper proposes a new packet scheduling algorithm that provides a fair, class based, delay jitter controlled packet scheduling scheme that manages handoff and buffer occupancy for 4G wireless access systems. Improved quality of service (QoS) in mobile broadband IP high-speed downlink packet access (HSDPA) networks is an important focus for next generation networks. The new packet scheduling algorithm is implemented at both the IP and radio layer and reduces the handoff packet drop rate and packet forwarding rate. The proposed algorithm includes a step that removes contention between users with almost the same fairness measure value.
