Energy conservation has been an important area of interest in Wireless Sensor networks (WSNs). Medium Access Control (MAC) protocols play an important role in energy conservation. In this paper, we describe CSMA based MAC protocols for WSN and analyze the simulation results of these protocols. We implemented S-MAC, T-MAC, B-MAC, B-MAC+, X-MAC, DMAC and Wise-MAC in TOSSIM, a simulator which unli...

Tactical software defined radio (SDR) networks demand stringent requirements of latency, throughput, and reliability. In the past, significant efforts have been made to achieve maximal efficiency with modifications improvements either in an individual layer or through cross-layer design its working protocol. this paper, we propose a novel consisting adaptive multi-input medium access control (A...

Magnetic artificial cilia (MAC) are small actuators inspired by biological found in nature. In microfluidic chips, MAC can generate flow and remove microparticles, with applications anti-fouling. However, the used for anti-fouling current literature has dimensions of several hundred micrometers length, which limits application to relatively large length scales. Here, biologically-sized magnetic...

in the present study, removal of dibenzothiophene (dbt) from model oil (n-hexane) was investigated using magnetic activated carbon (mac) nano-composite adsorbent. the synthesized nano-composite was characterized by ft-ir, fe-sem, bet and vsm techniques. the mac nano-composite exhibited a nearly superparamagnetic property with a saturation magnetization (ms) of 29.2 emu g-1, which made it desira...

Previous studies have demonstrated that the leukocyte integrin Mac-1 adheres to several cell surface and soluble ligands including intercellular adhesion molecule-1, fibrinogen, iC3b, and factor X. However, experiments with Mac-1-expressing transfectants, purified Mac-1, and mAbs to Mac-1 indicate the existence of additional ligands. In this paper, we demonstrate a direct interaction between Ma...

This paper presents LB-MAC, a new MAC protocol for asynchronous, duty cycle sensor networks. Different from existing sensor network MAC protocols that usually focus on reducing energy consumption and extending lifetime of individual sensor nodes, LB-MAC aims at prolonging the network lifetime through balancing the nodal lifetime between neighboring sensors. LB-MAC is lightweight and scalable as...

Mobile wireless sensor networks (MWSNs) have become a foremost solution in many emerging applications both industry and academia. Moreover, considering the mobile node WSN is challenging task to designing efficient communication protocols, specifically at medium access control (MAC) layer. Most of existing protocols consider only for static slow mobility. To meet with future MIoT applications, ...
