MOTEL: Mobility Enabled Wireless Sensor Network Testbed.

摘要

We propose a novel architecture for wireless sensor network testbeds, called MOTEL. The main novelty compared to existing architectures is the possibility to include mobile sensor nodes. To support mobility, we deal with two main challenges: controlled mobility of sensor nodes, and the need to operate sensor nodes in the absence of a backchannel. We address these challenges together with traditional testbed requirements such as experiment repeatability, on-node logging, debugging and re-programming. MOTEL consists of two main components: MuRobA, a coordinated multi-robot architecture for enabling controlled mobility of the sensor nodes, and FLEXOR, a flexible sensor network architecture for enabling backchannel-free WSN experiments. MOTEL is work in progress and here we present the general architecture design of both MuRobA and FLEXOR, along with our first implementation and evaluation.
