Provided is a system and method for a multicast routing algorithm to work in infrastructure based mesh networks. It chooses access points, fixed infrastructure gateway nodes connected to each other and/or the global internet via a wired/wireless backbone, as a group of local multicast group leaders to form a multicast group leader cloud. Each local multicast group leader is elected on-demand according to the local multicast group member's request. Each local multicast group leader forms a local multicast tree rooted at this leader connecting all multicast group members associated with the AP. The processes of electing and maintaining local multicast trees rooted at APs enable efficient coordination with underlying unicast routing to exploit the advantages of fixed infrastructure nodes. Therefore, routing overhead and multicast tree convergence time are reduced. The method can support large networks with fast topology change due to fast convergence and reduced routing overhead.

Apparatus and methods for efficient synaptic update in a network such as a spiking neural network. In one embodiment, the post-synaptic updates, in response to generation of a post-synaptic pulse by a post-synaptic unit, are delayed until a subsequent pre-synaptic pulse is received by the unit. Pre-synaptic updates are performed first following by the post-synaptic update, thus ensuring synaptic connection status is up-to-date. The delay update mechanism is used in conjunction with system “flush” events in order to ensure accurate network operation, and prevent loss of information under a variety of pre-synaptic and post-synaptic unit firing rates. A large network partition mechanism is used in one variant with network processing apparatus in order to enable processing of network signals in a limited functionality embedded hardware environment.

Adaptive rule-based methods to solve localization problems for ad hoc wireless sensor networks are disclosed. A large problem may be solved as a sequence of very small subproblems, each of which is solved by semidefinite programming relaxation of a geometric optimization model. The subproblems may be generated according to a set of sensor/anchor selection rules and a priority list. The methods scale well and provide improved positioning accuracy. A dynamic version may be used for estimating moving sensors locations in a real-time environment. The method may use dynamic distance measurement updates among sensors, and utilizes subproblem solving for static sensor localization. Methods to deploy sensor localization algorithms in clustered distributed environments are also provided, permitting application to arbitrarily large networks. In addition, the methods may be used to solve sensor localizations in 2D or 3D space. A preprocessor may be used for localization of networks without absolute position information.

A method and system for transparently combining remote and local storage to provide an extended file system such as a virtual local drive for a computer system client/user, e.g., a user of a pocket sized personal computer or a cable set-top box. A client device may load file system object data, storing the directories and files remotely, and retrieving the files only when required. Via its local storage, the extended file system handles unreliable connections and delays. When a connection to an extended file system server is present, the extended file system provides automatic downloading of information that is not locally cached, and automatically uploading of information that has been modified on the client. Extended file system attributes are employed to determine the actual location of file system data, and a lightweight protocol is defined to download or upload remote data by low-level components that make the remote source transparent from the perspective of the application. The system scales to large networks as it employs the lightweight protocol and establishes a connection only to retrieve and submit data.

In the area of network provisioning, there is a problem of selecting a suitable traffic-provisioning model for large networks due to the high management complexity of the resource-efficient trunk model and the poor bandwidth efficiency of the easy-to-configure hose model. The invention is based on the idea of partitioning at least part of the network into multi-node clusters, and defining traffic limitations on at least two levels, including the intra-cluster level and the inter-cluster level, where the traffic limitations include one or more node-to-cluster traffic limitations for inter-cluster traffic. Subsequently, cluster-based provisioning of the network is performed based on the traffic limitations. The novel node-to-cluster limitations proposed by the invention are preferably applied in a cluster-based trunk or hose model on the inter-cluster level. In other words, for the description of the inter-cluster traffic (traffic between the clusters) cluster-based trunk or hose models can be used, preferably depending on the available information about the traffic. The cluster-based provisioning makes it possible to find a trade-off between management complexity and overprovisioning.

A method and system for equivalence checking of logical circuits using iterative circuit reduction and satisfiability techniques provide improved performance in computer-based verification and design tools. By intertwining a structural satisfiability solver and binary decision diagram functional circuit reduction method, computer-based tools can make more efficient use of memory and decrease computation time required to equivalence check large logical networks. Using the circuit reduction technique back-to-back with the simulation technique, optimum local and global circuit reduction are simultaneously achieved. By iterating between the structural and functional techniques, and adjusting the size of sub-networks being analyzed within a larger network, sub-networks can be reduced or eliminated, decreasing the amount of memory required to represent the next larger inclusive network.

The invention discloses a software upgrading method and a software upgrading device which are used for solving the problems that update of application software of a mobile terminal occupies large network flow and is complex and inconvenient. Function codes finishing concrete program functions in a main program are extracted and packaged to form an implementation class, a call interface is abstracted, and the main program calls the implementation class through the call interface so as to finish the concrete program functions. When the function codes need updating, the main program acquires an implementation class of a new version, and the implementation class of an old version is replaced with the implementation class of the new version. When the software is updated, users only need to download code files of part of logic from a server so as to replace original code logic, and because updated content is only a subset of overall program codes, the occupied network flow is small. Under a silent update mode, the software automatically finishes an upgrading process during the software using process of the users, and accordingly the aim of silent update is achieved.
