Typically, a WSN consists of hundreds to thousands of tiny sensor nodes that communicate over wireless channels and perform distributed sensing and
collaborative data processing.
In this situation, Wireless Mesh Networks (WMN) [3-8] can be used to transmit vital information arising form the wireless Body sensor Network (WBSN) to the backbone network.
WMN are considered cost-effective alternatives to wireless LANs, as there is no necessity to deploy any wired infrastructure to support a mesh network.
The integration of WBSN and WMN technologies, results in Wireless Sensor Mesh
Network (WSMN) and this technique has already been proposed [9] by one of the authors of this paper, for usage in the medical field.
