We have seen that Mesh Networks which is 802.11S – an
extension of Wireless LAN can cover the entire city and
use multi hop routing in communication with very minimal
amount cabling used at the backbone. The nodes in mesh
networks can be mobile which can be a PDA, PC or laptop
and even wireless sensor networks. The mobile nodes
which in our case are wireless sensors can transmit the
sensed information to the nearest access point i.e. mesh
node which use multihop routing to transmit the
information to the wired network or even to mobile
devices like PDA or laptop. An integration of these two
technologies is Wireless Sensor based Mesh Network [11]
which is shown in Fig.4. Based on this background, a
Wireless sensor based Mesh Network architecture has been
proposed for health application and the same will be
discussed in the next section
