Ad hoc networks are mobile networks that can be formed spontaneously without the requirement of a centralized access point or an existing infrastructure. There are several unique characteristics of an Ad hoc network that differentiates it from other classes of networks. Most of the TCP variants have been designed in the context of wired networks and the reason of poor performance of TCP is due to ignoring the properties of wireless Ad hoc networks. For TCP to adapt itself to Ad hoc environments, several improvements have been proposed that helps to differentiate between different types of losses. This is because in mobile Ad hoc network losses are not always due to congestion.
