This paper proposes an intra-PAN mobility management scheme for IPv6 over Low-power wireless personal area networks(6Lo WPAN) on the basis of "networkbased" idea. We developed a tree-like network architecture which includes coordinate nodes for packet routing. All of the control messages are designed to transmit in link layer,and the sensor nodes are free to consider care-of address and the mobile nodes are unnecessary to deal with any mobility handoff messages. The simulation results show that this scheme efficiently cuts down the signaling cost and reduces the energy consumed by fixed nodes which can extend the life time of the whole Personal area networks(PAN).

Resource reservation is an effective measure to ensure end-to-end quality of service （QoS）, however, the burstyness of the traffic makes the reservation idle some time, and forms a waste of re- sources. Based on the analysis of active queue management （AQM） of DiffServ network, we propose a resource management scheme, which allows borrowing resources from unused reservation, accord- ing to the characteristics and advantages of cognitive networks. First, some nodes reserve certain proportion capacity for some special services （for instance, some services pay additional money） to guarantee the priority of these applications. Then resources are assigned according to the different parameters of services. If the available resource can not meet the requirements of new services, real- time ones are admitted with higher priority and allow borrowing the unused reservation from other nodes appropriately. Simulations show that, the proposed scheme has good performance at network resource utilization, the admission rate of new aDolications and OoS of users.

In this paper we consider a queueing network consisting of two parallel servers and threearrival streams generated by independent Poisson sources. Each server has its own queue and receivescustomers from its own arrival stream. A third arrival stream consists of customers which place resourcedemands on both servers, which are handled separately by each server once the request is made. Eachservice time is independent and exponentially distributed. Each customer in the system pays a holdingcost per unit time. The objective is to dynamically determine the optimal scheduling policy to the thirdstream of conupled customers. based on the state of the system, so as to minimize the average cost. Thismodel is new, and has Policy implications for computer or communication networks. A fuzzy approachis presented to solve this problem. Simulation shows that the approach is efficient and promising.

As a result of economic reform commencing in 1978 in China, cultural beliefs of the Chinese busines,owners are changing. While much has been published concerning large and multinational businesses, there is gap in knowledge of cultural beliefs of small and medium sized enterprises. To provide new knowledge, a survey or, these smaller sized enterprises located throughout China was conducted in the summer of 2006. Respondents were selected from urban and rural areas, coastal and inland provinces and various industries to provide information or, their opinions on how some of their cultural beliefs have changed from 1990 to present. Specific beliefs questionea include： Use of fengshui, Traditional Forbidden Activities, Company Naming Responsibility, Company Name Basis, Use of Numbers, Use of Physiognomy, and Prediction of a Company＇s Future. The importance of fengshui has risen aver in the last sixteen years and certain *** activities such as not turning over the fish while eating has remained important as a cultural belief. Naming a company is important and the desirability of a good name is bared on various factors. Use of numbers, physiognomy, and non-scientific methods for predicting the future success,of companies are of lesser use. These aspects of culture are reviewed in consideration of the change from a planned economy to amarket-based economy.
