EASITEST: A MULTI-RADIO TESTBED FOR HETEROGENEOUS WIRELESS SENSOR NETWORKS

摘要：

In this paper, we propose EasiTest, a multi-radio testbed for heterogeneous wireless sensor networks (WSN).Two types of sensor nodes, specifically, high speed multi-radio node (EZ271) and low speed single radio node (EZ521) are developed.An administration platform is provided to monitor and control the testbed.EasiTest enjoys high flexibility, powerful processing capability and ease of expansion.EasiTest provides a powerful tool not only for the study and evaluation of large scale, heterogeneous sensor networks, but also for quick prototyping of practical WSN applications.To demonstrate the capability of the testbed, we study the co-existence problem of IEEE 802.11 and IEEE 802.15.4.Guidelines are given on channel allocation and network parameter configuration to minimize the interference.
