Due to the fact that sensor nodes are untethered and unattended, energy management is a
critical issue in communication mechanism of a wireless sensor network. In this paper, we …

In order to eliminate the interferences between neighbors and reduce the delay, with the
respect of the real time constraint, we focus our work on the multi-frequency scheduling …

There are performance deficiencies that hamper the deployment of Wireless Sensor
Networks (WSNs) in critical monitoring applications. Such applications are characterized by …

MAC protocols have direct control over radio which is the most energy consuming part of a
wireless sensor node. TDMA based WSN MAC protocols are more energy-efficient than …

This paper introduces I-MAC a new hybrid medium access control protocol for wireless
sensor networks (WSNs). I-MAC combines both CSMA and TDMA techniques while …

Due to the half-duplex property of the sensor radio and the broadcast nature of wireless
medium, limited bandwidth remains a pressing issue for wireless sensor networks (WSNs) …

Sažetak In Wireless Sensor Networks (WSNs), collision handling during transmission of data
is an important challenge. MAC protocol plays a vital role in handling those collisions …

Earlier sensor network MAC protocols focus on energy conservation in low-duty cycle
applications, while some recent applications involve real-time high-data-rate signals. This …

This paper presents a Self-Reorganizing Slot Allocation (SRSA) mechanism for TDMA
based Medium Access Control (MAC) protocols in wireless sensor networks. With TDMA, a …

This paper proposes a distributed protocol for multiple slot assignment in a sensor network
for collision-free media access. In the first phase, the nodes reserve multiple slots of a fixed …
