Abstract-Service-oriented architecture is an important way for collaboration in mobile ad-hoc networks (MANETs). Yet, since MANETs are infrastructure-less, the traditional service discovery approaches will produces large amount of broadcast request packets which may cause a broadcast storm. In addition, due to the dynamic network topology and limited energy(More)
In the environment of Mobile Ad-hoc Networks (MANETs), devices can collaborate under the service-oriented architecture (SOA). However, as MANETs are infrastructure-less, devices may move randomly and join and leave the network at any time which leads to a permanently changing topology of the network. What adds to the unpredictability of the network is the(More)
Many developing countries are suffering from air pollution, especially the Particulate Matter with diameter of 2.5 micrometers or less (PM2.5). While quite a few air quality monitoring stations have been built by governments in a city's public areas, the indoor PM2.5 has not yet been monitored and dealt with effectively. Though many office buildings have an(More)
Many developing countries are suffering from air pollution recently. Governments have built a few air quality monitoring stations in cities to inform people the concentration of air pollutants. Unfortunately, urban air quality is highly skewed in a city, depending on multiple complex factors, such as the meteorology, traffic volume, and land uses. Building(More)
OBJECTIVE To investigate the mechanism of anti-inflammatory effect of diallyl sulfide (DAS) in protection against acute lung injury (ALI) in rats with paraquat poisoning. METHODS Eighty male Wistar rats were randomly divided into four groups, namely: control group, model group, dexamethasone (DXM) treatment group, and DAS treatment group, with 20 rats in(More)
