Data management in TestBed for large scale wireless sensor networks

Wireless sensor network (WSN) testbed design challenges can be divided into three main sub-categories: architectural, hardware and software. By considering all these challenges, an optimal solution was found and EDI TestBed created. In this paper, a method, which solves software related problems in large scale WSN testbed, such as how to distribute computational resources, control all of the testbed devices and how to efficiently acquire and structure the data, is described. The experimental test results shows that proposed method is advantageous for large scale testbeds (more than 20 sensor nodes), and its efficiency increases rapidly if the number of sensor nodes in testbed increases.
