A method and network architecture for implementing an energy efficient network. The network includes a plurality of nodes that collect and transmit data that are ultimately routed to a base station. The network nodes form a set of clusters with a single node acting as a cluster-head. The cluster-head advertises for nodes to join its cluster, schedules the collection of data within a cluster, and then transmits the data to the base station. A cluster can intelligently combine data from individual nodes. After a period of operation, the clusters are reformed with a different set of nodes acting as cluster-heads. The network provides an increased system lifetime by balancing the energy use of individual nodes.

Disclosed is a method of performing a contention based access in a UE of a mobile communication system. The method includes: triggering a BSR to an ENB if data to be transmitted to the ENB occurs; and triggering the contention based access if the BSR has been triggered. The method can minimize collision between signals transmitted in the uplink by multiple UEs through contention based transmission resources in a mobile communication system.

Improved apparatus for a radio communication system having a multiplicity of mobile transceiver units selectively in communication with a plurality of base transceiver units which, in turn, communicate with one or more host computers for storage and manipulation of data collected by bar code scanners or other collection means associated with the mobile transceiver units. A network controller and an adapter which has a simulcast and sequential mode provide selective interface between host computers and base transceivers. A scheme for routing data through the communication system is also disclosed wherein the intermediate base stations are organized into an optimal spanning-tree network to control the routing of data to and from the RF terminals and the host computer efficiently and dynamically. Additionally, redundant network and communication protocol is disclosed wherein the network utilizes a polling communication protocol which, under heavy loaded conditions, requires that a roaming terminal wishing to initiate communication must first determine that the channel is truly clear by listing for an entire interpoll gap time. In a further embodiment, a criterion used by the roaming terminals for attaching to a given base station reduces conflicts in the overlapping RF regions of adjacent base stations.

A method selecting a RACH comprises determining an access service class (ASC) associated with a unique access class of a user equipment (UE) by analyzing a radio resource control (RRC) message received from a UTRAN (UMTS (Universal Mobile Telecommunication System) Terrestrial Radio Access Network); receiving mapping information from the UTRAN; analyzing ASCs and scrambling codes to be used for available RACHs associated with each of the ASCs based on the received mapping information; mapping the analyzed scrambling codes to scrambling code groups associated with the ASCs; selecting a scrambling code group associated with the determined ASC; and selecting one of the scrambling codes using a total number of the scrambling codes mapped to the selected scrambling code group and a unique identifier of the UE.

Nodes in a network are clustered by first determining, in each node, a cluster head capability (CHC). The CHC is broadcasting, directly or indirectly, until all nodes have received the CHCs. Each node nominates, one or more candidate cluster heads based on the CHCs, and then, in each node, at least one cluster head is selected from the candidate cluster head nodes based on maximal CHCs.

This invention relates to a device, in one example embodiment, for the determination of the sequence of nucleic acids and other polymeric or chain type molecules. The device analyzes a sample prepared by incorporating fluorescent dyes at the end of copies of varying lengths of the sample to be sequenced. The sample is then vaporized, charged and accelerated in an evacuated chamber. The individual molecules of the sample are accelerated to different velocities because of their different masses, which cause, in one embodiment, the molecules to be sorted by length as they travel along the evacuated chamber. Once sorted, the stream of molecules is illuminated causing the fluorescent dyes to emit light that is picked up by a detector. The output of the detector is then processed by a computer to yield of the sequence of the sample under analysis. Such an embodiment improves over the art by using photo-detection of the individual molecules instead of measuring the time of flight to a detector that measures collisions. Unlike mass spectrometry, the method of such an embodiment does not require the extreme sensitivity required to differentiate between very small mass differences in large molecules. Such an embodiment is therefore more robust than the art and well suited for high throughput sequencing of, for example, various large nucleic acid molecules.

Each queue may be associated with a respective network packet type and a port of the plurality of ports.

A thin-film magnetic recording medium is produced by forming a laminate for magnetic data recording on a nonmagnetic substrate through a dry process, forming a protection layer on the laminate also through a dry process, plasma-etching the protection layer, and forming a lubricant layer on the plasma-etched protection layer. All steps are completed continuously in a vacuum without abrasion. The surface of the resulting recording medium is substantially smoother than the prior art.

A method and system broadcasts an alert packet in a wireless multi-hop network of nodes. An event is sensed in a source node of the network, and an alert packet is broadcast in response to sensing the event. The alert packet is received in a set of candidate nodes within a broadcast range of the source node. Each candidate node infers a distance between the candidate node and the source node based on a receive power of the received alert packet, and determines a priority for rebroadcasting the alert packet, wherein the priority is based on the distance to minimizing a probability of collisions while rebroadcasting the alert packet and extend a range of the rebroadcasting.
