Fair TDMA scheduling in wireless multihop networks
In wireless multihop networks, communication between two end-nodes is carried out by hopping over multiple wireless links. However, the fact that each node has to transmit not only its own traffic, but also traffic on behalf of other nodes, leads to unfairness among the communication rates of the nodes. Traditional Carrier Sense Multiple Access/Collision Avoidance (CSMA/CA) based media access c...
متن کاملScheduling of Broadcasts in Multihop Wireless Networks
Broadcast is an important operation in wireless networks. However, broadcasting by naive flooding causes severe contention, collision, and congestion, which is named the broadcast storm problem. Many protocols have been proposed to solve this problem, with some investigations focusing on collision avoidance yet neglecting the reduction of redundant rebroadcasts and broadcasting latency; while o...
متن کاملScheduling Algorithms for TDMA Wireless Multihop Networks
Scheduling Algorithms for TDMA Wireless Multihop Networks Petar Djukic Doctor of Philosophy Graduate Department of Electrical and Computer Engineering University of Toronto 2008 Current and future wireless standards use TDMA to provide guaranteed Quality-ofService (QoS) in the network. While these standards specify how transmissions should occur, they do not discuss scheduling algorithms to fin...
متن کاملProtocols for a Wireless-atm Multihop Network
Bernhard Walke, Stefan B ohmer, Matthias Lott Communication Networks, Aachen University of Technology, D{52074 Aachen, Germany Abstract A medium access control protocol for a wireless multihop network is described and evaluated. The network is able to guarantee the bandwidth contracted to a connection in a hidden station environment and to most e ciently use the spectrum capacity by providing ...
متن کاملBroadcast scheduling in wireless multihop networks using a neural-network-based hybrid algorithm
In wireless multihop networks, the objective of the broadcast scheduling problem is to find a conflict free transmission schedule for each node at different time slots in a fixed length time cycle, called TDMA cycle. The optimization criterion is to find an optimal TDMA schedule with minimal TDMA cycle length and maximal node transmissions. In this paper we propose a two-stage hybrid method to ...
