InactiveUS7055151B1Accurately match frame addressSimple data structureProgram initiation/switchingResource allocationOperational systemShared resource
In a multi-tasking pipelined processor, consecutive instructions are executed by different tasks, eliminating the need to purge an instruction execution pipeline of subsequent instructions when a previous instruction cannot be completed. The tasks do not share registers which store task-specific values, thus eliminating the need to save or load registers when a new task is scheduled for execution. If an instruction accesses an unavailable resource, the instruction becomes suspended, allowing other tasks' instructions to be executed instead until the resource becomes available. Task scheduling is performed by hardware; no operating system is needed. Simple techniques are provided to synchronize shared resource access between different tasks.

InactiveCN106131916AFast convergenceLittle remaining energyHigh level techniquesWireless communicationWireless networkResidual energy
The invention provides a wireless network route establishment method based on an ant colony algorithm. According to the method, information elements in the ant colony algorithm are adjusted. Three parameters of residual energy, path consumption energy and hop count are normalized into a route performance evaluation value for assignment. A source node broadcasts a route request. Backward information element tables are generated in the process of arriving at a destination node by a route request ant FANT. The destination node receives the FANT and generates a route response ant BANT. The BANT calculates a probability of selecting a next hop neighbor node through values of the backward information element tables. One-time self iteration is carried out on information element values corresponding to original information element tables by employing the highest value in the information element tables. The finally selected information element value corresponding to a next hop node is increased. Moreover, the information element values of the unselected nodes are decreased. Continuous iteration is carried until route establishment is finished. According to the method, the residual energy of each node is balanced through adoption of a multi-measure route discovering mode, and the service life of a network is prolonged.
