Capacity limitation is one of the fundamental issues in wireless mesh networks. The aggregate capacity can be increased by equipping each mesh router with multiple radios tuned into distinct frequency channels. However, most past research efforts that attempt to exploit multiple channels assume orthogonal channels of fixed pre-determined width, which prohibits the further effective use of spectrum...
Distribution center is a bridge connecting providers and clients. It plays an important role in logistics system. This paper put forward the least cost and the shortest time allocation models of materials distribution center. The integrated measure allocation models of materials distribution center considering the time and the cost together is built and a solution flow to the least cost and the shortest...
In this paper, we propose a novel resource allocation algorithm based on proportional fairness in multiuser OFDM systems. Because the utility function is always used for the optimization and achieving the tradeoff between the efficiency and fairness, the proportional fairness optimization problem can be formulated as maximizing the utility function, which is the sum of logarithmic user data rate....
Contract net protocol (CNP) and its extensions (CNCP, ICNP) have been widely applied to task allocation in muti-agent system (MAS). However, when being applied to large-scale MAS (LSMAS), they expose shortcomings such as low efficiency and large information amounts. To solve this problem, an improvement to CNCP was proposed in this paper, In which a method for deciding the bidding threshold of participant...
In multi-rate wireless LANs, throughput-based fair bandwidth allocation can lead to drastically reduced aggregate throughput. To balance aggregate throughput while serving users in a fair manner, proportional fair or time-based fair scheduling has been proposed to apply at each access point (AP). However, since a realistic deployment of wireless LANs can consist of a network of APs, this paper considers...
