PERFORMANCE EVALUATION OF AN IoT PROTOCOL

Abstract

The Internet of things is defined as making different things connected to the Internet as phone, refrigerator, traffic lights, smart home,street lights and even the person himself, where these things can communicate with each other and accomplished various tasks without human intervention. The goal of this technology is to improve individual life, making it safer and more luxurious, and helping him to save time and effort. IoT technologies areapplying in a lot of fields as health field, agricultural field, industrial field, self-driving cars and smart homes and cities, … etc And by virtue of the fact that devices in the Internet of Things are small and restricted in terms of energy, processing power and battery life and depend on wireless sensor networks (WSN)that are characterized by low-bandwidth and unreliable communication, the result is that many of these devices cannot provide an efficient and acceptable communication.In this work we have evaluated CoAP protocol, by evaluating the parameters: energy consumption, throughput, successfully delivered packets and delays, by simulating the protocol using the COOJA simulator, and studying the results obtained from the simulation then analyzing them to find its weakness and adventages. We have concluded, at the end of our work, that the CoAP protocol acheeve interoperability, reliability, and scalability. One of its weaknesses is the energy consumption in abundance
