This chapter discusses the issues Mobile Ad hoc Network (MANET) integration with the Internet are considered, with particular attention to the handover performance in the scenario where moving objects roam between different multihomed hybrid ad hoc networks. The Internet of Things is evolving to enable the seamless communication of moving smart objects with nodes on the Internet. The chapter provides a performance evaluation of the handover when different adjacent MANET subnetworks are connected to the Internet by means of their own gateway and mobile IP agent. An alternative architectural model for the Internet of Things may be a more loosely coupled, decentralized system of smart objects with sensing, processing, and networking capabilities. The communication between any pairs of objects inside a MANET is handled by ad hoc routing protocols, which were originally created to permit communication between MANET members away from network infrastructures.
