A MAC protocol for Industrial Wireless Sensor Networks (IWSNs) should deal with data
transmission in a timely, reliable, and energy-efficient manner. For reliability, various factors …

To cope with the internal and external interference induced by other ambient signals,
physical obstacles and the dynamic change of topology in wireless sensor networks, we …

Existing TDMA-based MAC protocols for wireless sensor networks are not specifically built
to consider the harsh conditions of industrial environments where the communication …

In this paper, we propose a new TDMA-based MAC protocol which aims at maximizing data
transmission parallelism with two channels. The proposed protocol includes two key …

Nodes in original S-MAC protocol just can visit the channel in the scheduling and listening
stage. The working schema may result in data latency and high conflict. To solve those …

Wireless Sensor Networks (WSNs) consist of many self organized sensor nodes to monitor
various activities like temperature, pressure, health condition, intrusion detection, etc. These …

In wireless sensor networks (WSN), sensor nodes are hardly recharged, so energy efficiency
is always considered to be of primary importance. However, recent applications, such as …

This paper proposes an energy-efficient and collision-free medium access control protocol
named TDMA-S (Time division multiple access MAC protocol for Sensor networks). Nodes in …

ABSTRACT Wireless Sensor Networks (WSN) is an emerging area of research in the field of
wireless communication [1]. WSN applications include environmental monitoring, industrial …

Limitations of current multi-channel MAC protocols include requiring of strict time
synchronization, existing large number of multi-channel hidden terminals, and lacking single …
