In the current world of technology, various physical things can be used for facilitation of a human work. That is why the Internet of Things,an innovative technology and a good solution which allows the connection of the physical things with the digital world through the use of heterogeneous networks and communication technologies, is used. The Internet of Things in smart environments interacts with wireless sensor network (WSN) and mobile ad-hoc network (MANET), making it even more attractive to the users and economically successful. Interaction between wireless sensor and mobile ad-hoc networks with the Internet of Things allows the creation of a new MANET-IoT systems and IT-based networks. Such the system gives the greater mobility for a user and reduces deployment costs of the network. However, at the same time it opens new challenging issues in its networking aspects as well. In this work, the authors propose a routing solution for the Internet of Things system using a combination of MANET protocols and WSN routing principles. The presented results of solution's investigation provide an effective approach to efficient energy consumption in the global MANET-IoT system.And that is a step forward to a reliable provision of services over global Future Internet infrastructure.
