Análise de desempenho dos protocolos CTP e RPL em ambiente móvel

Abstract

As the advancement of the Internet of Things, new devices will be able to connect to the internet and with this the challenges that arise to allow the network to absorb these new devices is huge. The current Internet still does not support in a wide and well sedimented way the Internet of Things deployment. There are several technological problems in the areas of security, mobility, quality of service and mainly scalability. Currently, companies works on the development of protocols to meet the new applications and the new traffic profile that the network will have, an area that has been much studied and will have a very deep impact on the Internet of Things viability is the new routing protocols development and adaptation, to have an idea if we only look at a wireless sensor network, where the energy availability is low, the routing protocol needs to take this issue into consideration, in order to make it a viable application. An example of a protocol that has evolved, not only but most because the increased demand for addressing, was the IP protocol, IPv4 supports approximately 4 billion (2 ^ 32) addresses, while IPv6 has an astronomic address numbers (2 ^ 128). The Internet of things is not limited to static objects, it is also made up for mobile devices, such as sensors that will be installed in cars, accompanying patients in their daily lives, in several harvesters, etc. The objective of this monography is to study the CTP and RPL protocols performance, developed for wireless sensor networks where the requirements related to the energy consumption are very constrained. To fully study and understand the protocols, simulations will be taken using a network simulator named COOJA that is installed in the operational system CONTIKI. Simulations will be made using static devices and mobile devices, and the performance will be compared on both cases.
