Evaluation of the Performance of IEEE 802.15.4 Based Wireless Sensor Network for Large Scale Application

In this paper, the authors evaluate the performance of IEEE 802.15.4 standard Wireless Sensor Network (WSN) in star, tree and mesh topology for large scale applications. This evaluation is performed to study the effect of deeply employed wireless sensor network on throughput, end to end delay, number of hops and packet drop caused by collisions when the number of nodes is increased. The network simulator OPNET (version 14.5) is used to perform their simulation. Based on this performance analysis, a comparison, and as a result a decision can be made on choosing the appropriate topology for the required application.
