A survey of TCP over ad hoc networks

The Transmission Control Protocol (TCP) was designed to provide reliable-to-end delivery of data over unreliable networks. In practice, most TCP have been carefully designed in the context of wired networks. Ignoring properties of wireless ad hoc networks can lead to TCP implementations with performance. In order to adapt TCP to the ad hoc environment, improvements been proposed in the literature to help TCP to differentiate between the types of losses. Indeed, in mobile or static ad hoc networks losses are not due to network congestion, as it is mostly the case in wired networks. In this, we present an overview of this issue and a detailed discussion of the major involved. In particular, we show how TCP can be affected by mobility and-layer protocols. In addition, we survey the main proposals that are intended to TCP to mobile and static ad hoc environments
