it is shown in [1] that the optimal downlink radio resource allocation for non-realtime traffic in cellular cdma/tdma networks can be mapped to a multi-dimensional multiple-choice knapsack problem (mmkp) which is np-hard. in this correspondence we propose a heuristic algorithm with polynomial time complexity for this problem. numerical results indicate significant computational performance impr...

This paper assumes each user has more than one queue, derives a new packet-dependant proportional fairness power allocation pattern based on the sum of weight capacity and the packet’s priority in users’ queues, and proposes 4 new cross-layer packet-dependant OFDM scheduling schemes based on proportional fairness for heterogeneous classes of traffic. Scenario 1, scenario 2 and scenario 3 lead r...

In this paper, an analytical model for evaluating the performance of a packet scheduling algorithm, called lookahead scheduling, is proposed. Using lookahead scheduling, each input port of a switch has B packet buffers. A packet arrives at an input port is scheduled for conflict-free transmission for up to B time slots in advance. If it cannot be scheduled for transmission in the next B slots, ...

In this paper the problem of packet scheduling in the node of packet-switched computer communication network is considered. Packet scheduling in the network edge nodes is one of the crucial mechanisms essential for delivery of required level of quality of end-toend network services (QoS). In order to satisfy QoS guaranties for each incoming request belonging to one of distinguished traffic clas...

The main cause of the wasted energy consumption in wireless sensor networks is the packet collision. The packet scheduling algorithm is therefore introduced to solve this problem. This paper presents an analytical model for predicting the performance of packet scheduling algorithms in wireless sensor networks. This model can be used to predict the performance of the packet scheduling algorithm ...

In this paper, packet loss probability performance in cell-based and packet-based switches with finite Input Queues (IQ) and iLPF scheduling algorithm are analysed. This algorithm has been proposed as a practical scheduling algorithm to achieve 100% throughput in cell-based switches. The scheduling algorithm is implemented in three cases: cellbased (CB-iLPF) switching, packet-based (PB-iLPF) sw...
