In a real-time wireless TDMA environment, every packet generated by applications has a deadline associated with it. If the system cannot allocate enough resources to serve QoS defines the call blocking probability and handoff dropping probability, whereas at packet level, or MAC level, QoS defines the packet dropping probability and delay tolerance. the packet before the deadline, the packet wo...

Unlike wired networks, packets transmitted on wireless channels are often subject to burst errors which cause back to back packet losses. Most wireless LAN link layer protocols recover from packet losses by retransmitting lost segments. When the wireless channel is in a burst error state, most retransmission attempts fail, thereby causing poor utilization of the wireless channel. Furthermore, i...

The high-performance computing paradigm needs high-speed switching fabrics to meet the heavy traffic generated by their applications. These are efficiently driven deployed scheduling algorithms. In this paper, we proposed two algorithms for input queued switches whose operations based on ranking procedures. At first, a Simple 2-Bit (S2B) scheme which uses binary procedure and queue size packets...

In scalable streaming service, there are two important knobs to effectively exploit the underlying network resource and to maximize the user perceivable quality of service(QoS): layer selection and packet scheduling. In this work, we propose Packet Scheduling algorithm for Scalable Video to address these issues. Using packet dependency graph, the proposed algorithm selects the layer to maximize...

In active and programmable networks, packet processing could be accomplished in the router within the data path. For efficient resource allocation in such networks, the packet scheduling schemes should consider multiple resources such as CPU and memory in addition to the bandwidth to improve overall performance. The dynamic nature of network load and the inherent unpredictability of processing ...

Code division multiple access mobile ad hoc networks (CDMA-MANETs) will be a next-generation wireless networking architecture to connect various military platforms. The classic contentionbased MAC protocols are inappropriate for tactical ad hoc networks, where more rigid requirements for the quality of service (QoS) (e.g., guaranteed packet delivery) have to be satisfied. In this paper, we prop...

This paper focuses on energy-efficient packet transmission with individual packet delay constraints over a fading channel. The problem of optimal offline scheduling (vis-à-vis total transmission energy), assuming information of all packet arrivals and channel states before scheduling, is formulated as a convex optimization problem with linear constraints. The optimality conditions are analyzed....

This paper presents an analysis of DSR protocol and packet scheduling algorithm to find those that most improve performance in congested network and proposes our algorithm to improve the performance of DSR protocol by using fuzzy logic in mobile ad hoc networks. Packet schedulers in wireless ad hoc networks serve data packets in FIFO order. Because, a scheduling algorithm to schedule the packet...
