Objects Communication Behavior on Multihomed Hybrid Ad Hoc Networks

Abstract

When objects connected to the Internet for sharing information move around, they usually need, as communication support, a Mobile Ad Hoc Network ({MANET}), which consists of a number of self-organized mobile nodes with routing capabilities. When a {MANET} connects to a fixed network, it is commonly known as hybrid ad hoc network. When more than one gateway connects a {MANET} to a fixed network, packets that pass from one network to the other may change the gateway they use dynamically. In this chapter, it is examined how the communications established between objects on a {MANET} with nodes on a fixed network are affected when the paths followed for their forwarded packets change the gateway in use. Two different scenarios are considered: one in which a {MANET} reactive routing protocol is used and one in which a proactive protocol is used. It is found that reactive protocols will have better communication behavior when objects are in movement.
