The fact that all this validation magic happens with just a single hidden form field for each field that you re validating is pretty impressive. But in practice, certain aspects of the result may not be entirely satisfactory. You need to get back to the validation error message that was automatically formatted for you. It tells the user what s wrong (for example, A value must be entered for the USERNAME field). Are you entirely happy with that result And how about that simple blackon-white message display Finally, it tells users to Please go back and correct the problem. Is that a good thing to recommend We look at each of these issues in the following sections.

known. Depending on the envisioned applications, the number of servers, sensors, and associated resources may vary signi cantly. For the scenario considered in Figure 16.2, each BSN has a controller, which is a sensor node equipped with more advanced processing capabilities. Only the controller is destined to communicate directly with external devices. Therefore, while the individual sensors may or may not communicate with one another, they all need to communicate with the controller. Overall, this hierarchical arrangement allows for a scalable design, with more ef cient resource utilization. 16.3.3.3 Resource Constraints in a BSN

Recall that the validation error message in Figure 20-2 read, A value must be entered for the USERNAME field. That happened automatically, and ColdFusion simply used the name of the form field that was being validated. It did uppercase the entire field name for us (we just used username), and the on-screen prompt does simply ask for USERNAME.

Caution Although it s not really about validation per se, consider that some users may be confused by a prompt on-screen requesting their Username. Most computer people recognize that as a prompt for the user s authentication identifier, often called a username or userid. A user may possibly enter his real name (bob or bob smith) rather than what you were expecting (perhaps bsmith ). This raises the issues of usability and human factors that are beyond the scope of this discussion, but at a minimum, consider prompting users for their Login or LoginID. Consider, too, that if you re developing an application from scratch, you may have better ways to uniquely identify a user than to force him to create and remember a contrived username. Perhaps the user s e-mail address would suffice, or an employee number if that s commonly known by all users of a corporate application. Of course, if this is leveraging the username of an enterprise security domain (see 40), prompting for that username or userid, however, it s known in that environment may make perfect sense.

According to the proposed prototypes and test beds found in the existing literature [4, 10 12], BSNs are envisioned to have computational and bandwidth resources on par with those found in the so-called microsensor networks [25, 26]. For example, the computational and storage capabilities of a BSN have been prototyped using UC Berkeley MICA2 motes [4], each of which provides an 8-MHz ATMega-128L microcontroller with 128 Kbytes of programmable ash and 4 KBytes of RAM. In fact, these motes may exceed the resources found in smaller BSN sensors. As such, to be safe, a proposed design should not overstep the capabilities offered by these prototype designs. Energy is ultimately the limiting factor in a BSN. And according to studies assessing the energy dispensed per bit of information, it is found that the most expensive resource is the communication operation [3, 11, 12, 26, 27]. By comparison, the computational costs are typically much smaller. As such, only information bits that are truly necessary should be sent over the channel. This guideline has profound repercussions for the security protocols to be adopted in a BSN. It essentially rules out many conventional asymmetric cryptographic algorithms [6, 8]. In fact, as in a
