Bluetooth-based Mobile Gateway for Wireless Sensor Network

چکیده
Sensor nodes are being increasingly deployed for monitoring different phenomena in a stand-alone manner or as a part of larger wireless sensor networks (WSN). In addition to protocols for communication within the WSN, sensor nodes may also support communication with other devices. These devices either represent gateways for exposing data and metadata to external networks, or serve as connection points to WSN for onsite calibration and maintenance. Advanced mobile terminals appear particularly suitable for such manners. This paper presents the implementation of a mobile gateway consisting of a Samsung i8910 smartphone and a Versatile Sensor Node (VSN) connected via Bluetooth, whose role is to interface between WSN using proprietary networking protocol and mobile network. The data obtained from WSN can be enriched using smartphone’s embedded sensors before being sent to the remote server. We show this on an example of geo-tagging with smartphone’s GPSbased location data. Keywords-mobile gateway; wireless sensor networks; metadata; adaptation layer; testbed

The mobile sink can increase the efficiency of wireless sensor networks. It moves in a monitored environment and collects the network nodes information. Thus, by the sink we can balance the power consumption and increases the network lifetime. Determining path of the sink's movement is usually modeled as an optimization problem where finding optimal solutions require collecting value of all the...

In this paper we proposed a Cellular Automaton based local algorithm to solve the autonomously sensor gathering problem in Mobile Wireless Sensor Networks (MWSN). In this problem initially the connected mobile sensors deployed in the network and goal is gather all sensors into one location. The sensors decide to move only based on their local information. Cellular Automaton (CA) as dynamical sy...
