In this paper, the resource allocation problem is considered for energy efficient spectrum access in a wireless cognitive radio ad hoc network, where each node is equipped with cognitive radio and has limited battery energy. The network is an OFDMA system operating on time slots. In each slot, the users with new traffic demand will sense the entire spectrum and locate the available subcarrier s...
Communication and cooling aware job allocation in data centers for communication-intensive workloads
Energy consumption is an increasingly important concern in data centers. Today, nearly half of the energy in data centers is consumed by the cooling infrastructure. Existing policies on thermally-aware workload allocation do not consider applications that include many tasks (or threads) running on a large set of nodes with significant communication among the tasks. Such jobs, however, constitut...
In recent years many papers have been published for energy-efficient resource allocation in a cellular OFDMA system. In this paper we carried out combined user scheduling and power optimization based on per subcarrier or per base station for each with maximum transmits power in coordinated BS. Here three definitions of the energy efficiency are considered for system design with channel rate and...
