Patent number: 8762121Abstract: Generating of the initial temperature value for a simulated annealing process in the placement of circuit components in the physical design of integrated circuit (IC) is based on previous partitioning, if any, of the IC components into bins. An iteration limit value is then assigned equal to the initial temperature value. The simulated annealing process is then performed on a current partitioning of the IC components into bins according to the iteration limit value. The IC components are partitioned further into an exponentially larger total number of smaller bins compared to a previous number of bins. The process is then repeated starting with the operation of generating an initial temperature value for the simulated annealing process until the number of circuit components in each bin is below a specified number.Type: GrantFiled: May 25, 2010Date of Patent: June 24, 2014Assignee: Northeastern University Technology Transfer CenterInventor: Huaiyu Xu

Patent number: 8756658Abstract: A requester node requesting a service in a peer-to-peer network transmits a request to a service provider node. The request may include a communication history of the requester node identifying other nodes with which the requester node has previously communicated. The service provider node authenticates the requester node based on the communication history. The service provider node may ask other nodes with which the requester node has communicated for evaluation of the requester node. The other nodes may calculate a trust metric of the requester node and provide this metric to the service provider node. The service provider node may use this trust metric in combination with a similarity calculation of the requester node and the service provider node to make a determination whether the requester node is to be authenticated. The service provider node may evaluate the requester node and store the evaluation in its communication history.Type: GrantFiled: June 11, 2010Date of Patent: June 17, 2014Assignee: Northeastern University Technology Transfer CenterInventor: Zhenhua Tan

Patent number: 8521714Abstract: Technologies are generally described for a peer to peer search routing algorithm and system. In one example, a node in a peer to peer network includes a processor. In some examples, the processor may be configured to receive information regarding a topology of the peer to peer network and generate a first search routing algorithm for the peer to peer network based on the topology. In some examples, the processor may be configured to generate a second search routing algorithm for the peer to peer network based on a search characteristic and the topology. In some examples, the second search routing algorithm is distinct from the first search routing algorithm. In some examples, the processor may be configured to receive a request to search the peer to peer network. In some examples, the processor may be configured to search the peer to peer network using the second search routing algorithm.Type: GrantFiled: August 25, 2010Date of Patent: August 27, 2013Assignee: Northeastern University Technology Transfer CenterInventor: Zhenhua Tan

Publication number: 20120137123Abstract: The present disclosure relates to an encryption/decryption device and method and a communication system including the encryption/decryption device. The device includes a receiving part; an address analyzing part; a judging part; an encrypting/decrypting part and a sending part. The judging part is adapted to judge whether an encryption/decryption process needs to be performed in accordance with the source address and/or the destination address of the data package. Thus, a safe network transmission of the user data is achieved without the need of installing and configuring software and the user is easy to realize the security of data transmission.Type: ApplicationFiled: August 5, 2010Publication date: May 31, 2012Applicant: NORTHEASTERN UNIVERSITY TECHNOLOGY TRANSFER CENTERInventor: Guangming Yang
