In a mobile ad hoc wireless networks (MANET), nodes communicate with each other via packet radios. However, in a MANET network, the mobility of the nodes and power limitations lead to an increased loss of connectivity between the mobile nodes when changing the route between nodes, which requires the routing table to be frequently updated. Hence, routing protocol plays an important role in updat...

Salah jurusan saat kuliah berdampak pada mahasiswa akan malas dan mendapat nilai yang kurang memuaskan. Jurusan seimbang dengan kemampuan mengakibatkan mengerti materi atau bahkan tidak menyukai perkuliahan diberikan. Maka sangat penting bagi seorang siswa untuk memilih sesuai bidang minat, bakat kemampuannya. Penelitian ini bertujuan memberikan rekomendasi program studi calon menggunakan metod...

We propose the so-called backup tree algorithm to compute a set of n-1 backup multicast delivery trees from the default multicast tree for application level multicast. For each backup multicast tree exactly one link of the default multicast tree is replaced by a backup link from the set of available links. The backup tree algorithm calculates the n-1 trees with a complexity of O (m log n).

We consider a finite capacity queueing system with one main server who is supported by a backup server. We assume Markovian arrivals, phase type services, and a threshold-type server backup policy with two pre-determined lower and upper thresholds. A request for a backup server is made whenever the buffer size (number of customers in the queue) hits the upper threshold and the backup server is ...

one of the current challenges and complications in the world is the climate change and global warming, which has numerous and varied effects and consequences in different regions. in this regard, the effects of economic activities on the increase in greenhouse gases and also the effects of greenhouse gases on economic activities have become increasingly controversial. in this study, an investig...
