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...
Our goal is to design an IEEE 802.11e/AFDX (WiFi with QoS/Avionics Full DupleX switched Ethernet) hybrid network. More precisely the aim is to guarantee the QoS requirements of AFDX traffics transmitted on an IEEE 802.11e wireless network, for on-ground maintenance applications. The AFDX requirements are related to the temporal constraints (latency and jitter). The use of IEEE 802.11e induces several...
According to multimedia service distribution such as High-Definition Television (HDTV), Internet Protocol Television (IPTV) and Voice Over Internet Protocol (VoIP), the networks are required to guarantee Quality of Service (QoS) and real-time performance. Power Line Communication Technology is used for data transfer as well as the transfer of electric power. However, power line communication has some...
Scheduling and channel assignment algorithms to provision longer-term backhaul traffic flows in infrastructure TDMA/OFDMA Wireless Mesh Networks (WMNs) with near-perfect QoS are described. A recursive fair stochastic matrix decomposition algorithm is used to compute transmission schedules for all provisioned backhaul traffic flows between BSs. Each schedule consists of a sequence of permutations which...
Algorithms to provision backhaul traffic flows in an infrastructure Wireless Mesh Network (WMN) with near minimal delay and jitter and near-perfect QoS are described. The WMN consists of Base-Stations with multiple radio transceivers for backhauling, and one or more Gateway BSs. It has recently been established in theory that a recursive fair stochastic matrix decomposition algorithm can be used to...
With the advent of new applications, one of the primary applications supported in downlink cellular systems is streaming video. QoS for streaming video entails data transmission to the mobile stations with limited latency and limited jitter. This requirement on latency and jitter can be mapped to the number of yet-to-be-played packets in a mobile station's buffer, to always be above a certain minimum...
