With the development of shipping industry, GPS has become an important guarantee for the safety of navigation in the ship ocean navigation. GPS can be widely used in the ship ocean voyages, because it provides accurate location information of the ship, exact timing. GPS can make an accurate calculation for the ship’s navigation parameters, in

The eventual emergence of Ad Hoc network provided an effective solution for any person exchange information at any time, any place with anyone in any way, its role under special circumstances is also can not be replaced by a wired network or cellular mobile networks and, therefore, attracted much attention of researchers. Ad Hoc network

In traditional ways, when we need to do the data acquisition, we often use the equipment to do this and go to the field. This way costs lots of human input and money. To solve these problems, a data acquisition based on wireless sensor networks is introduced in this paper. This solution realizes a four

With the rapid development of Internet, data traffic on backbone increases explosively, so does the demand of IP service. For the reason that IP traffic is burst, changeful, uncertain and unpredictable, the bandwidth can not be fully used in SDH or WDM optical networks, and it is hard to allocation and it is complicate to

The IC layout is a necessary step in the IC manufacturing process.It not only decides function of IC,but also affects performance,cost and power of IC at a large degree.In deep submicron technology,as the ratio of interconnect delay rises dramatically in whole chip delay,the timing closure become the most important issue of layout.The main task of
