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 ondemand
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.
