A gateway-based framework for transparent interconnection between WSN and IP network

Wireless Sensor Network (WSN) envisions ubiquitous computing future in many fields, such as environmental monitoring, military surveillance, and inventory tracking. These applications need -in many cases- to interconnect with IP networks. The fact that the WSN has its own application-specific non-standardized protocols presents a significant challenge to establish such interconnection. In this paper, we propose a generic gateway-based framework allows access to individual sensor nodes and enables network-based query for data-centric WSN. It also provides transparent access from one network to the other without modifying protocols running in either network. Moreover, this framework can be extended to use multi-gateways to provide fault tolerance and load balancing.
