An Integrated Framework for Wireless Sensor Web Service and Its Performance Analysis Based on Queue Theory

Abstract

Abstract. Wireless sensor networks (WSNs) have unlimited and extensive potential application in different areas. Right now, how to integrate WSNs into the web service or grid computing framework is becoming an issue in related research areas. In this paper, we proposed an integrated web service framework for WSNs, and built mobile device hosted web service, moreover we built its corresponding queueing model and gave it performance analysis. Analysis and simulation show that our framework is practical in QoS guaranteed messages transmitting with different priority.

Modeling and Performance Analysis on a Delay Tolerant Differentiated Wireless Sensor Web Service Framework

“…In WSNs, it is impossible for all nodes to be connected with wired network or Internet, usually only the sink nodes in WSNs which have high battery energy will connect with wired network or Internet (See Fig.1 in [1]). Different from the computer hosted wired web service provider, web service hosted wireless sensor nodes only have limited battery , to save the energy, if there is no data request, nodes in WSNs are usually in power saving state which will lead intermitted network connection and the service may be unavailable.…”

“…Apart from this, most of current studies did not provide their corresponding mathematics model and give performance analysis. Though [1] put forward a framework for integrating sensor web service and gave corresponding model and performance analysis for it, [1] did not address the issue of delay tolerant web service from the protocol layer, moreover [1] the queueing model for [1] framework is M/G/1 non-preemptive priority with vacations. As in real world, the buffer size for any queueing is finite; we think a delay tolerant network similar protocol and M/G/1/k nonpreemptive priority with vacations queueing system would be more practical.…”

“…Considering nodes in WSNs are resource constrained embedded devices, [1] gave an integrated web sensor framework.…”

“…As in real world, the buffer size for any queueing is finite; we think a delay tolerant network similar protocol and M/G/1/k nonpreemptive priority with vacations queueing system would be more practical. Due to these issues we think the following challenges need to be addressed: (1). The delay tolerant sensor web service framework for WSN; (2).…”

“…Right now, there are many research works on some specific applications. These research usually put forward some frameworks [1][2][3][4][5][6][7][8][9][10][11] under the assumption of the network connection is reliable and the latency is small. Actually in real WSNs, these assumptions do not hold.…”
