Maintenance of old city infrastructure such as bridges, roads and sewer pipes is one of important issues. We have proposed drifting sensor network architecture designed for observing gases and images in sewer pipes inexpensively and safely. This paper describes the implementation of active node selection algorithms designed for drifting sensor networks on Arduino/XBee based sensor nodes and the experimentation...
Wireless sensor network is a kind of data centric network, which transmit sensing data to sink nodes. Considering energy constraints, how to make full use of the limited energy to work reliably becomes a main research area in wireless sensor networks. In this paper, we propose a vote based cluster head election algorithm. In this algorithm, nodes vote to others who owning more remaining energy, and...
Wireless sensor network (WSN) has become monitoring solution of variety of applications. As one of the key technologies involved in WSNs, node fault detection is indispensable in most WSN applications. Faults occurring to sensor nodes are common due to the sensor device itself and the harsh environment where the sensor nodes are deployed. The goal of this paper is to locate the faulty sensors in the...
