A Prediction Based Cross-Layer MAC/PHY Interface for CDMA Ad Hoc Networks
نویسندگان
چکیده
Variable environments in ad hoc networks require a joint control of physical (PHY) and medium access control (MAC) layers resources in order to optimize performance. In this paper, we propose a framework to perform such cross-layer control and optimization. The PHY layer and cross-layer engine estimate and predict the channel variations to select the users that will meet the signal-to-interference-noise ratio (SINR) requirement in the next time slot, for MAC layer optimization. We consider high capacity code division multiple access (CDMA) ad hoc networks working at fixed quality of service (QoS) requirement where nodes are equipped with matched filter receivers.

On Cross Layer Congestion Control for CDMA-based Ad-hoc Networks
We investigate a cross layer congestion control technique for TCP Reno-2 (NewReno) in CDMA-based wireless ad-hoc networks in which both TCP layer and PHY layer jointly control congestion. The PHY layer varies transmission power based on the channel condition, interference power received and congestion in the network and seeks to transmit at a minimum power level, whereas the TCP layer controls ...
متن کاملEfficient Beaconless Geographic Cross-Layer Routing Protocol: CoopGeo for Optimal Relay Selection in Wireless Ad Hoc Networks
Ad hoc wireless network is an autonomous self organizing system of mobile nodes connected by wireless links where nodes not in direct range communicate via cooperation of intermediate nodes. To achieve efficient communication benefits from cooperation, more interactions at higher protocol layers, particularly the MAC (Medium Access Control) and network layers, are vitally required. For this pur...

متن کاملQuality of service implications of power control and multiuser detection-based cross-layer design
In order to allow for dense spatial reuse in wireless ad hoc networks, multiple access interference must be dealt with. This calls for advanced physical layer techniques, such as multiuser detection or power control. However, these techniques can only be efficiently applied to ad hoc networks when they are part of a joint PHY/MAC cross-layer design. In order to better understand both, the poten...
متن کاملA MAC-PHY Cross-Layer Protocol for Wireless Ad-Hoc Networks
Cooperative communications is a promising technology that tends to change the conventional access and transmission schemes in wireless networks. By enabling additional collaboration from nodes that otherwise will not directly participate in the transmission, it enables spatial diversity and dramatically improves the performance of the network. In this paper we propose a cross-layer cooperative ...
