Performance evaluation for high speed vehicle in VANET

Vehicular Ad hoc Networks (VANETs) is a high dynamic emerging technology for supporting wireless communication among vehicles. Communication via routing packets over the high-speed vehicles is a challenging task. Vehicles mobility speed can varies depending on the road specification. However in highways speed can be increased up to 120 – 200 Km/hr. moving in high speed can affect the efficiency of data delivery. In particular V2I traffic where moving car trying to deliver data to fixed space units which are designed to collected and process data from vehicles. In this paper, we investigated the consequences on increasing vehicle mobility speed in term of data delivery evaluation metrics including network throughput, delay and packet delivery ration. Results shows that in high speed mobility VANET, network throughput it decreased, and packet delivery ration is decreased as well

Simulated Annealing for Location Area Planning in Cellular networks

LA planning in cellular network is useful for minimizing location management cost in GSM network. In fact, size of LA can be optimized to create a balance between the LA update rate and expected paging rate within LA. To get optimal result for LA planning in cellular network simulated annealing algorithm is used. Simulated annealing give optimal results in acceptable run-time.Comment: 7 Pages, JGraph-Hoc Journa

Bank ownership and efficiency in China: what lies ahead in the world’s largest nation?

China is reforming its banking system, partially privatizing and permitting minority foreign ownership of three of the dominant ‘big four’ state-owned banks. This paper seeks to help predict the effects of this change by analysing the efficiency of virtually all Chinese banks in the years 1994–2003. Our findings suggest the big four banks are by far the least efficient and foreign banks the most efficient while minority foreign ownership is associated with significantly improved efficiency. We present corroborating robustness checks and offer several credible mechanisms through which minority foreign owners can increase Chinese bank efficiency. These findings suggest that minority foreign ownership of the big four is likely to significantly improve performance.foreign banks; efficiency; foreign ownership

TimeTrader: Exploiting Latency Tail to Save Datacenter Energy for On-line Data-Intensive Applications

Datacenters running on-line, data-intensive applications (OLDIs) consume significant amounts of energy. However, reducing their energy is challenging due to their tight response time requirements. A key aspect of OLDIs is that each user query goes to all or many of the nodes in the cluster, so that the overall time budget is dictated by the tail of the replies' latency distribution; replies see latency variations both in the network and compute. Previous work proposes to achieve load-proportional energy by slowing down the computation at lower datacenter loads based directly on response times (i.e., at lower loads, the proposal exploits the average slack in the time budget provisioned for the peak load). In contrast, we propose TimeTrader to reduce energy by exploiting the latency slack in the sub- critical replies which arrive before the deadline (e.g., 80% of replies are 3-4x faster than the tail). This slack is present at all loads and subsumes the previous work's load-related slack. While the previous work shifts the leaves' response time distribution to consume the slack at lower loads, TimeTrader reshapes the distribution at all loads by slowing down individual sub-critical nodes without increasing missed deadlines. TimeTrader exploits slack in both the network and compute budgets. Further, TimeTrader leverages Earliest Deadline First scheduling to largely decouple critical requests from the queuing delays of sub- critical requests which can then be slowed down without hurting critical requests. A combination of real-system measurements and at-scale simulations shows that without adding to missed deadlines, TimeTrader saves 15-19% and 41-49% energy at 90% and 30% loading, respectively, in a datacenter with 512 nodes, whereas previous work saves 0% and 31-37%.Comment: 13 page

Further evidence on the link between finance and growth: An international analysis of community banking and economic performance

We seek to contribute to both the finance-growth literature and the community banking literature by testing the effects of the relative health of community banks on economic growth and investigating potential transmission mechanisms for these effects using data from 1993–2000 on 49 nations. Data from both developed and developing nations suggest that larger market shares and higher efficiency rankings for small, private, domestically owned banks are associated with better economic performance, and that the marginal benefits of larger shares are greater when the banks are more efficient. Only mixed support is found for hypothesized transmission mechanisms through improved financing for SMEs or greater overall bank credit flows. The data from developing nations is also consistent with favourable economic effects from foreign-owned banks, but unfavourable effects from state-owned banks.banks, community banking, SMEs, financial development, economic growth, international
