Performance Evaluation of Zig-Bee 802.15.4 WPAN Designed in Satellite Subnet Using Opnet Modeler

In this advanced generation of science and technologies, nothing seems to be impossible. The new emerging technologies have made every dream possible. This paper deals with Zig-Bee wireless technique. The Zig-Bee wireless personal area networks (WPANs) are ad-hoc low power networks that are basically applicable in short range distance in low cost. These networks are made up of several to large number of devices/nodes which include a coordinator, routers and end devices.

The efficiency of these networks is based on the routing protocol implemented. The purpose of this work is to study the network performance created in satellite subnet in Opnet modeler 14.5. In satellite subnet, the network communicates with the satellite. The global network parameters which are evaluated for the performance of the network are Throughput, Traffic Data Sent, Traffic Received and Load.
