A good scheduling algorithm in wireless networks is the key for the efficient use of wireless medium. This paper presents a hybrid scheduling algorithm, called Contention-Vector based Hybrid Scheduling (CVHS) algorithm, for wireless networks wherein stations can sense each other. Examples of such wireless networks include wireless LANs and small wireless ad hoc networks. CVHS offers collision-free...
In this paper we have proposed an adaptive scheduling algorithm to suit group mobility scenarios in the mobile WiMAX. The QoS scheduling scheme aims to minimize the end-to-end delay for real-time traffic. IEEE 802.16e is a wireless broadband network standard aimed at providing robust, high data rate mobile communication. The issue of group mobility in mobile WiMAX networks has not been explored so...
In this paper, a framework for joint topology-transparent scheduling (TTS) and quality-of-service (QoS) routing in mobile ad hoc networks is proposed. Inspired by the fact that TTS can guarantee single-hop QoS support without the overhead due to the re-computation of transmission schedules when the network topology changes, TTS is chosen as the medium access control (MAC) in both the control and data...
This paper explores the attributes, layering models and objective functions in cross layer designs for mobile ad hoc wireless networks by taking all the statistical characteristics and constraints from the physical (PHY) layer, media access control (MAC) layer and network (NET) layer into consideration. This paper reviews the entire network optimization across all the PHY/MAC/NET layers. At the PHY...
