On the basis of the original algorithm, a kind of optimization algorithm is proposed in consideration of node properties and for the sake of energy utilization being balanced. Combining AODVjr Algorithm with Cluster-Tree Algorithm, traditional ZBR Algorithm has the shortcoming that some nodes would degenerate to RN-nodes and then become death nodes because they transmit too much data during which energy is consumed too fast. In view of this situation, improved Algorithm is put forward which establishes energy identifier energy_flag and energy judgment value Ejudge, refines RN+ nodes and clearly maps node properties in transmission path to numerical values. It also defines Q value so as to select optimal path according to energybalanced and short-time transmission principles. RREQ transmitted from different paths would be grouped and qualitatively analyzed. It reduces the rate of RN+ nodes degenerating to RNnodes, decreases the probability of RN- nodes participating in routing transmission, lengthens lifetime of nodes and increases life cycle of network.

One sort of greenhouse environment parameter monitoring system based on WSN is designed on account of problems of traditional greenhouse environment parameter monitoring system including complex wiring, high cost, poor monitoring flexibility and the disadvantage of high energy consumption of general wireless sensor network. System hardware mainly consists of CC2530 wireless sensor network transmission module, humiture sensor, carbon dioxide density sensor, etc. It utilizes protocol stack Z-Stack to make system underlying software and develops upper-computer software of greenhouse environment parameter monitoring system on the basis of VB software platform which help realize the real-time acquisition, transmission, storage and browse on greenhouse environment parameters. Experiment results show that utilizing wireless sensor network technology to do monitoring on greenhouse environment parameter simplifies measurement mode of traditional wired greenhouse environment monitoring system, leads monitoring area of the whole system to be more flexible and strengthens its expansion capability.

In this paper, the author researched the improvement of proactive workload management based on the multiobjective genetic algorithms. The authors were irresolute between building a new simulation environment or utilizing an existent one. The answer for this question was to find a suitable simulation which provide most of the main component of Cloud environments; accordingly, after a deep investigation we clarify that CloudSim simulator package satisfy the elemental requirements to start tasting the PWM model.

Designing and implementing an effective three-tier client/server system to support the new business paradigm is the focus of this document. To fully realize the potential of the three-tier architecture, this paper makes the middle layer easily accessible to multiple front-ends. The middle tier is running on a separate machine. This allows it to be accessible to multiple clients and it provides for the maximum performance. A prototype system was built using the business transaction of a certain Commercial Bank as the case studies. The experiment result shows that the three-tier client/server system has better performance in distributed big data management. Source

Cationic polyacrylamide (CPAM) were used extensively in water treatment, enhanced oil recovery and sludge dewatering. The review summarized the synthesis methods research progress of cationic flocculants. Four groups of synthesis technologies of cationic copolymers were reviewed, including aqueous solution polymerization, dispersion polymerization, inverse emulsion polymerization and photo initiated polymerization. Furthermore, the paper reviewed that the application of cationic flocculants in sludge dewatering treatment. Based on these reviews, the future research perspectives of synthesis and application on cationic flocculants in sludge dewatering treatment were proposed. Source
