Handovers and Interference Mitigation in Healthcare Environments

October 17, 2005
Author(s)
Nicolas Chevrollier, Nicolas Montavont, Nada T. Golmie
In this article, we consider candidate wireless technologies such as IEEE 802.11b, and IEEE 802.15.4 that can support medical and healthcare informatics applications. The main questions that we try to answer are: (1) is there any potential for significant
