Performance Evaluation of CoAP and UDP using NS-2 for Fire Alarm System


Objective: In this work, we measure the performance metrics for the combination of Constrained Application Protocol (CoAP) and User Datagram Protocol (UDP) protocols. Method: In this work, number of nodes is changed to check the performance of CoAP and UDP and ns-2 simulator is used to simulate Fire Alarm System. Findings: Throughput values are high for multiple servers compared to single server and the values increase with the number of nodes. It is helpful in saving a person’s life and prevents property loss when there is a fire accident since the packets are processed at a faster rate. Overhead, delay and packet loss values are less for multiple servers compared to single server which is an advantage but the values increase when the number of nodes increase which is disadvantageous in case of fire accidents as the packets might not reach on time or it might be lost during transmission. For single server, the values for overhead, delay and packet loss kept fluctuating for different number of nodes. Novelty: CoAP protocol implementation in ns-2 and comparison of performance for single server and multiple servers.
