IPv6 Wireless Sensor Network Gateway Design and End-to-End Performance Analysis

摘要

The need for low power personal area network (LoWPAN) devices to be connected to the Internet is increasing due to the demand and proliferation of new applications. Previously, these devices didn't have the need to be connected to Internet With the introduction of IPv6 over Low power personal area network (6LoWPAN), and the push for Internet of Things(IoT), these devices are now reachable using the common TCP/IP stack. Gateway is an important component to ensure that the packets from LoWPAN network are properly routed to the Internet This paper provides a new gateway architecture to support 6LoWPAN stack and the performance analysis for end-to-end communication in an office environment The architecture can be used for implementation in various 6LoWPAN related applications. Performance is measured on the latency and transmission success rate. The experiment results shows that the communication between WSN and client using the 6LoWPAN gateway is successful. Besides that the success rate is 100% for 1 hop and slightly lower in 2 hops. The latency rate between 100 and 135 ms is acceptable and comparable with existing prior art which is 125 ms on average.
