Cross-layer Packet-dependant OFDM Scheduling Based on Proportional Fairness
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...
متن کاملDependency of Transport Functions on IEEE802.11 and IEEE802.15.4 MAC/PHY Layer Protocols for WSN: A Step towards Cross-layer Design
In WSN, transport layer protocol plays a significant role in maintaining the node’s energy budget. To find out the dependency of Transport layer on MAC/PHY layer, the authors have extensively tested various transport protocols using IEEE 802.11, IEEE 802.15.4 MAC/PHY protocols for WSN. For IEEE802.11 and IEEE802.15.4 with RTS/CTS ON the TCP variants has shown >80% packet delivery ratio and 5-20...
متن کاملMAC Layer Multicast: Theory, Approaches and Protocols
The paper is directed towards designing bandwidth efficient strategies for MAC layer multicast. Bandwidth efficiencyof wireless multicast can be improved substantially by exploiting the fact that several receivers can be reached at theMAC layer by a single transmission. However, this feature can be effectively exploited only by resolving several decisionproblems and protocol challen...
متن کاملLiterature Review of MAC, Routing and Cross Layer Design Protocols for WSN
A WSN is composed of a large number of sensor nodes that are communicating using a wireless medium. The sensor nodes are deployed in the environment to be monitored in ad hoc structure. In WSN, there is sink node that collects data from all sensors, and usually not all nodes hear all other nodes. WSN is considered a multi-hop network. Although a WSN is a wireless multi-hop network, the ease of ...
متن کاملSurvey of MAC Layer Protocols for vehicular Ad Hoc Network
Vehicular Ad Hoc Network is currently challenge for the wireless networking and its researchers. In this paper we have proposed the survey of the different MAC Layer protocols of the wireless medium those can be implemented in the Vehicular Ad Hoc Networking. The survey is based upon the study of the different protocol on their MAC level and its performance factors is evaluated. The performance...
