Abstract
RPL (Routing Protocol for Low Power and Lossy Networks) has been designed for low power networks with high packet loss. Generally, devices with low processing power and limited memory are used in this type of network. IoT (Internet of Things) is a typical example of low power lossy networks. In this technology, objects are interconnected through a network consisted of low-power circuits. Example IoT applications are smart energy grid, smart home, connected car, intelligent transport systems, and smart cities. IoT is different from many similar technologies due to the existence of low power electronic circuits and limited connectivity. Information security is one of the main IoT concerns. The emergence of new types of security vulnerabilities in IoT devices and the escalation of their damages through numerous IoT applications is considered a major deployment drawback for RPL. In this paper, major cyberattacks against RPL, as well as related security solutions are addressed. Then, these solutions are classified and their weaknesses and strengths are investigated. Finally, it discusses the state-of-the-art status of information security in RPL.

Abstract
Wireless network technology made it possible to communicate easily using the electromagnetic waves leading to removing the biggest barrier in portable communications. As these networks use the air as the communication medium which leads to face with more vulnerabilities. Wireless networks play a vital role in our life in a way that all devices ranging from local modems to organizational equipment are utilizing the most common coding approaches to exchange data on the network. As such, if a person could enter this network, he would be able to attack against the users connected to network. In this essay, the penetrating methods in wi-fi wireless network applying the WEP and WPA WPA2 coding protocols would be investigated which are playing the most important role in local and organizational wireless communication. However, the WPA3 is suggested in order to eliminate all the security problems, yet not all the communication instruments in Iran are equipped with this coding system. On the other side, the WEP protocol is the first mostly used to be attacked followed by the first and second versions of WPA.
