Data dissemination scheduling algorithm for V2R/V2V in multi-channel VANET

Considering that the data dissemination in multi-channel VANET (vehicular ad hoc network),a cooperative data dissemination scheduling algorithm was introduced for V2R(vehicle to roadside unit) and V2V(vehicle to vehicle).The algorithm created initial scheduling operators according to data requisition of vehicles.Then,initial collision graph and collision matrix were generated based on the conflict among initial scheduling operators.After proving the positive semidefinite of collision matrix,SDP (semidefinite programming) was used to channel allocation and collision graph creation.The algorithm then assigned weights for each data requisition according to dwell time and data volume of vehicles in RSU service region.Furthermore,it selected maximum weighted independent set of collision graph.The goal was to satisfy the most urgent data requisitions by V2R/V2V cooperate transmission.Transportation simulation results demonstrate that the proposed solution effectively promotes the service capacity by utilizes the multichannel of VANET and V2R/V2V transmission scheduling.

Design and Implementation of HL7 V3 Gateway

Although the health data exchange standard of Health Level 7(HL7) V2.x (Version 2.0-2.5) has been widely used in hospital and has served well in these few years, the process that hospitals apply the standard of data transfer is very difficult. Because there is no explicit methodology in the HL7 V2.x development process, the gateway design is very complex. However, V3 strives to improve the V2 process and its outcomes. In this paper, the authors present an HL7 V3 gateway design based on the Web Services which can solve the problems of the HL7 V2.x. Web Services is an information exchange protocol regardless of the implementation pla(form, and is currently the main technology in enterprise application integration (EA1). We firstly introduce how to build HL7 V3 gateway with Web Services, then focus on the design of ilL7 gateway, finally realize the parsing and transmission of ilL7 V3 message.
