Wireless sensor networks (WSN) have wide range of application such as traffic analysis,
environmental monitoring, industrial process monitoring, and tactical systems. Large-scale …

Medium access control (MAC) protocols play a crucial role in energy efficiency, latency
reduction for sensor networks. Although some existing MAC protocols have achieved certain …

By reducing interferences drastically, time division multiple access (TDMA) based
approaches are considered one of the most efficient solutions to optimize resources' use …

Duty cycling improves energy efficiency but limits throughput and introduces significant end-
to-end delay in wireless sensor networks. In this paper, we present a traffic-adaptive …

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 …

In wireless sensor networks (WSNs) that use TDMA-based scheduled channel access,
spatial re-use of time-slots is possible among a nonconflicting set of nodes. In this way, data …

In this paper, we propose a novel local framing preschedule scheme to improve energy
saving in CSMA/TDMA hybrid MAC layer of wireless sensor network. This MAC combines …

PEDAMACS is a Time Division Multiple Access (TDMA) scheme that extends the common
single hop TDMA to a multihop sensor network, using a high-powered access point to …

How to shorten the time for channel waiting is critical to avoid network contention. Traditional
MAC protocols with CSMA often assume that a transmission must be deferred if the channel …
