- Sensor Networks for Emergency Response:Challenges and Opportunities
The major problem that researchers are experiencing with sensor networks is that sensor nodes have extreme resource limitations in protocol design, application development, and security models. Senor nodes are extremely limited in communication and computational capabilities. Amongst the obvious concerns with sensor networks, there are other issues that arise in these systems. The main issues are discovery and naming, robust routing, prioritization of critical data, security, and tracking device locations. Researchers have proposed methods to help solve these key issues. For discovery and naming, researches believe that is if the discovery process is decentralized then this will help avoid any single point of failure. To enhance the robustness of routing protocols, ad hoc routing techniques should be implemented to extend an effective communication range by having devices relay messages for one another. When many devices share this bandwidth, the critical data should be given priority over other traffic, and by employing this method the issue of prioritization of critical data is solved. Using many wireless devices such as GPS, RF signals, and ultrasounds will help with location awareness. Security is an essential concern with many sensor networks so having an efficient establishment of security credentials will significantly help secure such systems.
The CodeBlue infrastructure integrates sensor nodes and other wireless devices into a disaster response setting and provides facilities for ad hoc network formation, resources naming and discovery, security, and in-network aggregation of sensor-produced data. CodeBlue is designed for rapidly changing, critical care environments. Nevertheless, MoteTrack is a RF-based location tracking system specifically designed for disaster response. It operates using the low-power, single chip radio transceivers founding networks nodes, which rescue personnel can easily wear or embed in wearable vital sign sensors. These two methods are strongly emphasized due to the fact that using these kinds of protocol and software in disaster response scenarios will help track and monitor patients and responders.
The issue of a lost of batter power during rescue missions needs to be further examined. How much are these devices going to cost the medical community to employ in their field?
The authors should strongly emphasize more about the security attacks and countermeasures associated with the CodeBlue and MoteTrack systems. Security is a key issue in any sensor networks where outside influence can be embedded. Hostile threats can come from anywhere at anytime and security features have to be able to protect the system from any breaches that may occur. Privacy is what each job is to provide to the end user.
