Coverage: In WSN, each sensor node is given a glimpse of the environment. This follows are limited in range and accuracy (Figure 1), it can only include a limited physical area of environment. Therefore, coverage is also an important design parameter in WSNs. Each node receives a local view of its environment, limited by the scope and accuracy of it. the coverage of a large area composed by the union of a number of smaller insurance. Connectivity: Most of the high density of WSNs sensor, thus preventing the isolation of the nodes. However, mobility deployment, and other failures of the network topology, so does not guarantee connectivity. | ADVANCES IN MECHATRONICS Edited by Horacio Martinez-Alfaro Advances in Mechatronics Edited by Horacio Martinez-Alfaro Published by InTech Janeza Trdine 9 51000 Rijeka Croatia Copyright 2011 InTech All chapters are Open Access articles distributed under the Creative Commons Non Commercial Share Alike Attribution license which permits to copy distribute transmit and adapt the work in any medium so long as the original work is properly cited.
