Experimental Performance Evaluation and Feasibility Study of 6lowpan Based Internet of Things

Abstract

Nowadays, demand for low power, small, mobile and flexible computing machines that interconnects are growing rapidly. This study highlights internet of things (IoT) model regarding sensor node discovery and IPV6 framework using 6LoWPAN. Contiki network simulator (cooja) was used to examine the performance of the proposed network. The simulator was chosen because it provides good graphical user interface environment and allow rapid simulation setup found to be best in simulating network involving 6LoWPAN. Three experiments were carry out with the network topology designed to have 3, 7 and 5 motes respectively. The parameters considered in the simulation were throughput and packet loss which were examined using packet generation rate of 1 to 50 packet/sec with a constant delay. GET requests was sent to the humidity and temperature sensor motes running CoAP servers, and the corresponding throughput were observed in each case per experiment, it was observed that there was a 10 packet per second increase before it finally dropped This was because of the packet loss due to the increase in traffic. GET request was sent to motes to obtain the packet loss and the packet that were not acknowledged determined the packet loss. In this study, the performance of the proposed model in terms of throughput and packet loss was studied and the expected results will aid in planning 6LoWPAN network, A transition flow diagram was evolved for this work to represent packet routing process.
