WECalc: A Network Life Time Predictor Tool for WSN Applications
並列摘要
The aim of this study is to design a software tool for lifetime estimation for Wireless Sensor Network (WSN) applications simulated using Global Mobile System Simulator (GloMoSim). WSN are emerging because of the developments in wireless communication technology and miniaturization of the hardware. The solutions developed for WSN applications focus more on maximizing the lifetime of the network. The parameters such as number of nodes, data rate, MAC protocols, sampling rate, etc., influence the lifetime of a WSN application. In this paper, a sophisticated GUI based software tool called WECalc: Wireless Energy Calculator is designed to accept user inputs and to invoke GloMoSim. The advantages of WECalc tool are threefold. 1. Easy simulation of WSN applications through this GUI. 2. Flexible changes to various parameters that influence the lifetime and calculation of network lifetime prior to real time deployment. 3. A value addition to GloMoSim for WSN applications. The designed tool was experimented with changes in number of nodes, node position, MAC protocol, routing protocol, traffic pattern, etc., and the network lifetime was calculated which extends the utility of GloMoSim to WSN applications also. From the results obtained using this tool, it is observed that the MAC protocol with RTS-CTS mechanism performs well and routing protocol with on-demand route establishment mechanism increases the lifetime in WSN applications. Also, lifetime of the network depends on number of nodes involved in the path between source to sink and network lifetime is reduced when the sampling rate is increased.
