According to the different optimization objects, peer selection strategy can be divided into three categories: robustness of system and load balance oriented, streaming quality oriented and network topology conglomeration oriented. This thesis describes their basic characters, typical methods and the latest progress, and also simulates the peer selection(More)
This paper gives a definition of the communication overhead among nodes in task scheduling and resource management in grid environment, presents rules of building QoS routing tree based on the QoS routing algorithm, proposes grid heap-sort algorithm and QoS routing algorithm, and designs a scheme of grid task scheduling with the help of them. The results of(More)
In advance reservation environment, failure discovery strategy is very important to keep the normal running of whole system. One job's overtime (exceeding its booked time) may lead to a serious of jobs' abnormal termination in co-allocation environment. So there should be some strategies to solve this problem. In this paper, a novel overtime-tolerance(More)
Cognitive Radio Vehicular Ad Hoc Networks (CRVANETs) can resolve the conflicts between limited spectrum resource and vehicular communication service needs, and thus it receives much concern. Most existing routing solutions for Cognitive Radio Ad Hoc Networks (CRAHNs) or VANETs cannot be directly applied to CR-VANETs due to the high mobility of vehicles and(More)
With the growing number of smartphone users, peer-to-peer ad hoc data forwarding is expected to occur more often. The forwarding performance improves when knowledge regarding the expected topology and the social context information of the networks. In this paper, we introduce a new metric for data forwarding based on social context information, in which(More)
