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 …

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 …

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

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 …

In this paper, we propose a light-weight and adaptive scheduling-based media access
control protocol (LASMAC) for wireless sensor networks. Our primary goal is to achieve an …

S-MAC is hybrids of CSMA and TDMA approaches that use local sleep-wake schedules to
coordinate packet exchanges and reduce idle listening. In this method, all the nodes are …

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 …

Being different from other networks, the load and direction of data traffic for wireless sensor
networks are rather predictable. The relationships between nodes are cooperative rather …

This paper proposes a dynamic slot scheduling for tasks having different time constraints
executed over wireless sensor networks (WSN). These tasks may have different priorities …

Abstract Time Division Multiple Access (TDMA) protocols are considered an energy-efficient
solution to prolong wireless sensor network lifetime. However, their drawbacks such as the …
