Introduction
Wireless sensor networks (WSNs) [1][2] are a significant
technology attracting considerable research attention in
recent years. Recently it has started attracting attention
towards the health industry for monitoring the health of the
patient. 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. The sensors being low powered and
low memory devices can transmit the information to the
nearest mesh nodes and these mesh nodes can use
multihop routing to transmit the information to the
backbone networks like the PDA or the servers for health
