Quality of Service (QoS) of IEEE 802.11e is currently under research for the upcoming multimedia applications over broadband wireless networks. IEEE 802.11e is a contention based channel access function that uses the enhanced distributed channel access (EDCA) techniques. EDCA statically resets the Contention Window (CW) after each successful transmission. This article discusses a fuzzy logic ap...

With the advance of science and technology, people have a desire for convenient and comfortable living. Creating comfortable and healthy indoor environments is a major consideration for designing smart homes. As handheld devices become increasingly powerful and ubiquitous, this paper proposes an innovative use of smart handheld devices (SHD), using MIT App Inventor and fuzzy control, to perform...

A new method is proposed for the dynamic obstacle avoidance problem of unmanned surface vehicles (USVs) under international regulations preventing collisions at sea (COLREGs), which applies particle swarm optimization algorithm (PSO) to window approach (DWA) reduce optimal trajectory finding time and improve timeliness avoidance. Meanwhile, a fuzzy control designed dynamically adjust weight coe...

Logistics enterprises attach great importance to customer satisfaction. This paper focuses on satisfaction, and innovatively designs the measurement formula of which provides a theoretical basis for construction model. In addition, multi-objective planning distribution route optimization model with fuzzy time window is constructed further seek minimum transportation cost maximum The improved pa...

Fuzzy extractor is a powerful but theoretical tool to extract uniform strings from discrete noisy data. Before it can be used in practice, many concerns need to be addressed in advance, such as making the extracted strings renewable and dealing with continuous noisy data. We propose a primitive fuzzy embedder as a practical replacement for fuzzy extractor. Fuzzy embedder naturally supports rene...
