In ad hoc network, one needs other nodes to relay data packets. But resources in each node are limited. Therefore, these nodes may not relay other¡¦s data packet without getting any benefit. In this paper, a routing path selecting algorithm based on price mechanism is proposed. It helps nodes to get some benefits by relaying others¡¦ data packets. Moreover, the algorithm we proposed selects a routing path with less payment and more resources. Simulation results show that the drop rate, block rate and the cost of routing paths are reduced compared to the competing algorithms.

Since China established professional basketball league in 1995, China aimed to be the world's second professional basketball league. During this period, China¡¦s professional basketball league has experienced so many change and transformation of its policy. The study is build on the reexamination of theories and the establishment of analytical framework, in order to analyze China¡¦s professional basketball league development and transition of economic efficiency. The study discovered that the main problems in China's professional basketball competition market are¡Gthe market supply is uneven distribution¡Fthe whole market less than the size¡Fthe existence of market failure in price regulation¡Fthe existence of market supply and demand imbalance¡Fthe commission¡Ðagency relationship is bad¡Fmore market control¡Flack of market management and service awareness¡FThe relevant legal system is imperfect. In order to solve the problem from several aspects¡Gspeed up the market system and market cultivation and perfection of the elements¡Fstrengthen the market environment, including the CBA league organization, establish a reasonable system of property rights and governance structures¡Fstrengthen the external environment, including the creation of a good policy, formulate and improve relevant laws and regulation system.

During the past few years, the housing price has increased for both Sweden and the United Kingdom, and according to previous studies there can be many reasons for this development. The purpose of this study is to investigate the degree of differences and similarities between two housing markets. Specifically, this study explores how investors and buyers of housing acts on different markets, and how this changes the price development. The two regions this study focuses on are Greater Stockholm, in comparison with Greater London during the time period January 2005 until December 2018. The theories used are the Greater Fool theory and the Market Process theory, to analyze the result from the regressions run for this study. In the empirical study, time series were used, where several independent variables examined the potential connection to the housing price development. One time series was used for Greater Stockholm, and one time series for Greater London. The result of the study gave ambiguous indications, where most of the variables did not show statistical significance. This means that the change in these variables is not likely to affect the development of housing prices. While two variables for Greater London turned out to be statistically significant. / Priserna på bostäder har under de senaste åren ökat för både Sverige och Storbritannien. Enligt tidigare studier kan det finnas många skäl till denna utveckling. Syftet med denna studie är att undersöka graden av skillnader och likheter mellan två bostadsmarknader. Mer specifikt, undersöker studien hur investerare och köpare av bostäder agerar på olika marknader, samt hur detta förändrar prisbildningen. De två regioner som studien lägger fokus på är Storstockholm i jämförelse med Storlondon under tidsperioden januari 2005 till december 2018. Greater Fool-teorin och Marknadsprocess-teorin har använts för att analysera resultat från regressioner som gjordes för denna studie. I den empiriska studien användes tidsserier där flertalet oberoende variabler undersökte den potentiella kopplingen till prisutvecklingen på bostäder, en tidsserie för Storstockholm och en tidsserie för Storlondon. I resultat av uppsatsen gavs tvetydiga indikationer, där de flesta av variablerna inte visade på statistisk signifikans, vilket innebär att förändringen i dessa variabler troligen inte påverkar prisutvecklingen på bostäder. Medan två variabler för Storlondon visade sig vara statistiskt signifikanta.
