Energy conservation has been the key focus of research in low-rate wireless personal area networks (WPANs). Several algorithms have been proposed to dynamically adjust the duty cycle of nodes in beacon-enabled WPANs. Increasing beacon interval for lowering the duty cycle of end devices decreases the probability of fast node association, when passive scan is used. Moreover, the requirement of performing...
In this paper, we present a new MAC protocol satisfying with both high energy efficiency and low transmission latency at the same time over wireless sensor network, named as medium reservation preamble based MAC (MRPM). Unlike other synchronized duty cycle MACs, MRPM does not have separate time frames for SYNC and data traffics. Both traffics are integrated in a short listen period. Also, the channel...
In this paper, we present a new medium access control (MAC) protocol called Radio Triggered Sensor MAC (RTM) protocol that is expected for the next generation sensor network. The proposed RTM is a cross-layer MAC protocol which utilizes the passive radio sensor hardware for efficient medium access. The passive radio sensors harvest the energy from the wireless signal and energize itself. The passive...
Reduction of power consumption and network's life expansion are crucial for a wireless sensor network (WSN). This is typically performed by introducing low duty cycle in a sensor node. A special challenge in WSNs is transmission of a large amount of data, like images and video, that is becoming more and more required in various applications. A wireless network is very much prone to communication errors...
