Implementation and performance comparison of two similar Zig-Bee 802.15.4 WPANs in Mobile Subnet and satellite subnet using OPNET Modeler

The latter half of the twenty first century in India will witness the nascent technological advancements and the same will offer a highly complex and competitive environment. Service providers will be experimenting new options for ensuring seamless services in minimum time with the motif of spearheading competitiveness. Wireless technology revolutionized technical environment by offering many more options and Zig-Bee 802.15.4 has been one among the same. Zig-Bee 802.15.4, a IEEE specification for a high level protocol stack that uses small low-power and low-cost radios based on IEEE 802.15.4 standard for Wireless Personal Area Network (WPAN). In this work, performance of a network created in Mobile Subnet and satellite subnet is compared for MAC layer and Application layer. The parameters which are significantly assessed are delay, throughput, data traffic received and load. Both the scenarios are simulated using OPNET Modeler 14.5. The study compares the performance level of Zig- Bee in Mobile Subnet and Satellite Subnet.
