Abstract
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 for WSN-IP network interconnection. This 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.
