A system design of connecting wireless sensor networks and WiMAX accessing networks

To connect wireless sensor networks and WiMAX accessing system, a system is proposed in this paper. It is composed of two parts. The first part is used to establish a P2P network of multiple wireless sensor networks (WSNs) named as ¿WSN Peer Group (WPG)¿. This part is implemented by using JXTA platform. In the WPG, sensor informations can be shared peer to peer by sensor networks. The second part is to connect the WPG to the WiMAX accessing network which is implemented by the WiMAX Gateway (WG). As the WG is developed for the WPG, not for certain WSN, this new system proposes a new way for WSNs to access to WiMAX, which avoids developing various gateways for different types of WSNs. The performances on connectivity and delay are tested, and the results validates that the system is feasible.
