Learning, self-scheduling TDMA (LeSS-TDMA) for sensor networks
2008 IEEE Sensors, 2008This paper proposes LeSS-TDMA, a novel approach for scheduling TDMA activity in a sensor network, where nodes create their own schedules by learning from previous activity. The protocol uses routing information to establish a schedule appropriate for periodical data gathering, which is the main traffic type in sensor networks.

Greedy Scheduling of MIMO OFDMA: TDMA, FDMA/TDMA, or SDMA/FDMA/TDMA
IEEE Vehicular Technology Conference, 2006In multiuser MIMO system, multiuser multiplexing and diversity gain can be achieved by spatial scheduling. However, the limited battery life and terminal size of the User Equipment (UE) in a cellular system put a constraint on MIMO when the tranmitter has more antenna than the receiver in downlink, the conventional MIMO schemes can only exploit partial

Provable fairness for TDMA scheduling
2015 IEEE Conference on Computer Communications (INFOCOM), 2015We consider the task of assigning time slots on a user-dependent and time-varying wireless channel. This scheduling problem occurs in cellular networks due to the presence of channel fading and user mobility. We introduce a simple notion of global fairness, where each of n users is guaranteed a 1/(n + e) fraction of its total possible throughput, for ...

Learning, self-scheduling TDMA (LeSS-TDMA) for wireless sensor networks
2008 4th International Conference on Intelligent Computer Communication and Processing, 2008This paper proposes a novel approach for scheduling TDMA activity in a sensor network, where nodes create their own schedules by learning from previous activity, called LeSS-TDMA. The protocol uses routing information to establish a schedule appropriate for periodical data gathering, which is the main traffic type in sensor networks.

CP-TDMA: Coloring- and Probability-Based TDMA Scheduling for Wireless Ad Hoc Networks
IEICE Transactions on Communications, 2008This paper addresses the issue of transmission scheduling in wireless ad hoc networks. We propose a Time Division Multiple Access (TDMA) scheduling scheme based on edge coloring and probabilistic assignment, called CP-TDMA. We categorize the conflicts suffered by wireless links into two types: explicit conflicts and implicit conflicts, and utilize two ...

Improving Throughput using Cooperating TDMA Scheduling of Wireless Sensor Networks
International Conference on Computer and Information Technology, 2020Lifetime of wireless sensor network (WSN) can be increased by clustering method. In a cluster, cluster heads (CH) assign TDMA time slots to all member nodes or sensors sending data to their CH within allocated time slots.

Computational Method Using Quantum Annealing for TDMA Scheduling Problem in Wireless Sensor Networks
International Conference on Signal Processing and Communication Systems, 2019In this paper, we consider a wireless sensor network where the network topology is a tree and medium access control is TDMA. We focus on TDMA scheduling problem studied in [1]. Since scheduling problems are considered as a member in the class of NP-hard,

TDMA-ASAP: Sensor Network TDMA Scheduling with Adaptive Slot-Stealing and Parallelism
2009 29th IEEE International Conference on Distributed Computing Systems, 2009TDMA has been proposed as a MAC protocol for wireless sensor networks (WSNs) due to its efficiency in high WSN load. However, TDMA is plagued with shortcomings; we present modifications to TDMA that will allow for the same efficiency of TDMA, while allowing the network to conserve energy during times of low load (when there is no activity being ...
