Displacement. While crackdowns do not inevitably lead to displacement of crime and disorder, it does occur in some cases. The same rationality that police count on to deter some offenders causes others to adapt to police tactics and continue offending at the same rate. 21 Depending on the extent and direction of displacement, police risk criticism for creating problems in areas previously unaffected. Once again, the potential for criticism does not necessarily make crackdowns inadvisable; sometimes, displacing a problem from an area that has suffered disproportionately, to other areas that haven't, can be justified as a more equitable distribution of suffering. Displacement, where and when it does occur, seldom occurs at 100 percent. That is, the problem usually decreases in some way, even as it shifts. The key is to be aware of the various possibilities for displacement, develop intelligence systems that inform you how the problem is shifting, and counteract it if possible.
How will having three main points help me write my paper? As you do your research, you can concentrate on sources that give you statistics, examples, reasons, and opinions to support each point. You can ignore material that is not related to your main points. (See The KU Handbook for Writers , pp. 60-64.) As you write your draft, you can expand each of the bullet points in the Content section into a full paragraph. (See The KU Handbook for Writers , pp. 107-110, for a more detailed explanation.)
WSN nodes resource constrained. In order to keep the size and the cost of the nodes down, the nodes have limited processing power, memory and radio range. However, the resource constraint which has the most significant impact on many WSNs is the constraint on energy. WSN nodes are battery operated. Many wireless sensor networks are deployed in locations where battery replacement is not feasible. A node has to be discarded when the battery depletes. Energy scavenging may alleviate this problem in some sensor networks. Most WSN protocols are very conscious of the limited supply of energy, and try to conserve energy.
