A schedule-based approach, such as time division multiple access, is more efficient than a
contention-based approach in terms of energy saving by switching sensors into sleeping …

In this paper we propose SPARE MAC, a TDMA based medium access control (MAC)
scheme for data diffusion in wireless sensor networks (WSNs). The rationale behind SPARE …

In this paper, we present a new MAC layer protocol for wireless sensor networks that
reduces energy consumption and provides Quality of Service (QoS) guarantees through the …

The design of medium access control (MAC) in wireless sensor networks (WSNs) poses
several key factors such as energy conservation, bandwidth utilization, throughput, etc. This …

This paper describes a power-efficient distributed TDMA slot scheduling algorithm which the
slot allocation priority is controlled by distance measurement information in details. In our …

This article reviews the state-of-the-art energy-efficient contention-based and scheduled-
based medium access control (MAC) protocols for mobile sensor networks (MSNs) by first …

This paper presents a medium access control and scheduling scheme for wireless sensor
networks. It uses time trees for sending data from the sensor node to the base station. For an …

A wireless medium access control protocol that uses a topology-dependent slot schedule is
vulnerable to link failures. This becomes severer in industrial fields due to node mobility and …

Wireless sensor networks (WSNs) consist of multiple sensor nodes, which communicate with
each other under the constrained energy resources. Retransmissions caused by collision …

Several media access control (MAC) protocols proposed for wireless sensor networks
assume nodes to be stationary. This can lead to poor network performance, as well as fast …
