    Internet of Things dikenal juga dengan singkatan IoT merupakan sebuah konsep yang bertujuan untuk memperluas manfaat dari konektivitas internet yang tersambung secara terus-menerus. Untuk mendukung iot diperlukan analisa QoS yang baik. Quality of Service (QoS) didefinisikan sebagai suatu pengukuran tentang seberapa baik jaringan komputer memberikan layanan. QoS didesain untuk membantu end user menjadi lebih produktif dengan memastikan bahwa end user mendapatkan performansi yang handal dari aplikasi berbasis jaringan. Metode FAHP (Fuzzy Analytical Hierarchy Process) digunakan untuk mendapatkan bobot dari beberapa kriteria yang telah ditentukan. Setelah menentukan bobot, selanjutnya data diolah menggunakan model keputusan yaitu TOPSIS (Technique for Order Preference by Similarity to Ideal Solution). Metode ini digunakan untuk memberikan penilaian alternatif yang akan dipilih berdasarkan bobot dengan peringkat. Kedua metode dikombinasikan untuk menghasilkan suatu proses sesuai dengan kriteria yang diinginkan. Integrasi pendekatan FAHP dan TOPSIS dapat memberikan bobot yang sesuai kriteria dan memberikan hasil seleksi yang baik. Adapun hasilnya dari beberapa access point di LAB yang dipantau menunjukkan nilai rata rata QoS hasil uji verifikasi berkisar pada 86% setelah dilakukan perbaikan instalasi

    Selective Sensing Framework for Opportunistic Mobile Phone Sensing Networks

    The rise of opportunistic mobile phone sensing paradigm is due to ubiquitous mobile phones usage. Optimisation of battery energy consumption and achieving required spatial coverage of sensing area are important issues under opportunistic mobile phone sensing networks. Human mobility enable collection of mobile phones sensor data and sensing area coverage by forming communication network with surrounding neighbors devices (mobile phones). This paper proposes a human mobility based selective sensing framework called as HWSS (Human Walk based Selective Sensing) for sensor data collection in opportunistic mobile phone sensing networks. In proposed HWSS method, mobile phones are selected for sensing task based on users current and predicted future locations and sensing overlap area. The proposed HWSS method is compared with non-selective sensing method (NSS), where all mobile nodes are allowed for sensing during sensor data collection process, in an given application area. The simulation results show that compared to NSS method proposed HWSS method achieves reduction in energy consumption and required spatial coverage

    Smartphone como gateway móvel para a Internet das Coisas em ambientes sujeitos a atrasos e a interrupções

    A Internet das Coisas (IdC) possui algumas limitações em termos de conectividade, nomeadamente em meios que possuam dificuldades de acesso à rede de Internet, como os que estão sujeitos a atrasos e a interrupções. Neste contexto, o smartphone é usado como elemento estrutural ao nível da comunicação na IdC, sendo que vários autores propõem a sua utilização como gateway e como elemento central de Redes Tolerantes aos Atrasos e às Interrupções. O problema identificado pode ser dividido em três desafios: funcionamento do smartphone como gateway para mediar a passagem dos dados; armazenamento local dos dados, em casos de inexistência de conectividade; e sincronização dos dados para coincidirem com os da Cloud. Cada desafio corresponde a um requisito: armazenamento de dados na Cloud; ligação entre a camada sensorial e a Cloud; e utilização de dispositivos de prototipagem para a IdC. Para validar a abordagem, foi desenvolvido um protótipo cuja implementação se baseia na recolha local e no envio dos dados para a Cloud, aquando da existência de ligação à Internet, funcionando o smartphone como gateway para IdC. O protótipo assenta nas temáticas das Plataformas de Cloud para a IdC, dos Middlewares Orientados a Mensagens e dos Dispositivos para a IdC
