The following Java APIs are used for fast Code 39 decoding from image file source. The first group allows you to choose Code 39 as target barcode symbol and direct our Java barcode decoder control to detect and read this barcode type only.

Any other node that hears the RTS and/or CTS message defers its transmission until the ongoing transmission is over The CTS message prevents collisions with the data packet at the destination node B, while the RTS message prevents collisions with the ACK message at the source node A Nodes transmit their control and data packets at a xed (maximum) power level The carrier sensing MAC protocols are simple, but overly conservative This leads to low spatial reuse, low energy ef ciency, and high cochannel interference For example, consider the situation in Figure 113, where node A uses its maximum transmit power (TP) to send packets to node B If omnidirectional antennas are used, the region reversed for the communication between node A and B is the union of the regions circled by the RTS transmission range, the CTS transmission range, and the physical carrier sensing range.

It pays for the media to embellish on the past and promote what I call the gossip for the game You need to learn how to filter out the gossip-for-the-game syndrome versus acquiring a true market consensus It is a different situation when you listen to one person s opinion and follow that advice It helps to know that person s record of accomplishment If he or she is reasonably good, you may have more confidence as a trader to put on a trade But remember, verify, verify, verify Listen, form an opinion, check the fundamentals, verify that by looking at the charts, and then verify that by looking at some technical indicators This is a technique that will help in your trading discipline and help filter out these opinions, which can distract you from making good trading decisions.

92 STATIC POSITIONING OF NODES Node placement schemes prior to network startup usually base their choice of the particular nodes positions on metrics that are independent of the network state or assume a xed network operation pattern that stays unchanged throughout the lifetime of the network Examples of such static metrics are area coverage, internode distance, and so on Static network operation models often assume periodic data collection over preset routes In this section we give an overview of the different categories of static node positioning and discuss sample work from the literature We cover both sensor and base-station placement in distinct subsections 921 Sensor Node Placement As mentioned before, the position of nodes have dramatic impact on the effectiveness of the WSN and the ef ciency of its operation In this section we discuss contemporary sensor placement strategies in the literature.

According to CSMA/CA, since nodes D and E fall into the reserved region, they have to refrain from transmission (either data or control packet) to avoid interfering with the ongoing transmission between A and B However, it is easy to verify that the three data transmission A B, D C, and F E can be active simultaneously if nodes are able to synchronize locally and select appropriate transmission powers Furthermore, all the necessary transmit power will be less than the maximum transmit power level de ned in 80211, which means that much energy can be saved..

We classify them according to the deployment schemes, the optimization objective of the placement, and how they relate to the network topology Deployment Schemes Sensors can generally be placed in an area of interest either deterministically or randomly The choice of the deployment scheme depends highly on the type of sensors, application, and the environment in which the sensors will operate Controlled node deployment is viable and often necessary when sensors are expensive or when their operation is signi cantly affected by their position Examples of such scenarios include when populating an area with highly precise seismic nodes and when placing imaging and video sensors On the other hand, in some applications, random deployment schemes are the only feasible option This is particularly true for harsh environments such as a battle eld or a disaster region.

Due to the bene ts of increasing spatial reuse and energy conservation, powercontrolled MAC protocols have been intensively studied The basic idea of powercontrolled MAC protocols in the literature is as follows Nodes exchange their control packets (eg, RTS/CTS packets) at the maximum allowable power level in order to reduce the collision probability of DATA and ACK packets, but send their DATA and ACK packets at the minimum power level necessary for reliable communication They can be classi ed into three categories: contention-based, interference-based, and scheduling-based schemes, which will be discussed in detail in the following subsections Contention-Based MAC Schemes BASIC Schemes In BASIC power control schemes [2 5], RTS and CTS packets are sent at the highest( xed) power level (Pmax ), and DATA and ACK packets are sent at the minimum power level necessary to communicate with each other.

Depending on the node distribution and the level of redundancy, random node deployment can achieve the required performance goals Deterministic deployment is usually pursued for indoor applications of WSNs Examples of indoor networks include the Active Sensor Network (ASN) project at the University of Sydney in Australia [15], the Multiple Sensor Indoor Surveillance (MSIS) project at Accenture Technology Labs in Chicago [16], and the Sensor Network Technology projects at Intel [17] The ASN and MSIS projects gear for serving surveillance applications such as secure installations and enterprise asset management At Intel, the main focus is on applications in manufacturing plants and engineering facilities for example, preventative equipment maintenance (Figure 92)..
