A Heterogeneous Network abbreviated as HetNet is a mix of macrocells, picocells, femtocells, remote radio heads and relays. A HetNet is a network consisting of various wireless access technologies and functionalities. The next generation mobility technique called the 4G deals with the multi-access heterogeneous wireless networks which provide seamless connectivity of multimedia services at a higher data rate to the end users. There are various research challenges like self-organization, backhauling, handover and interference for the 4G The various handover mechanisms with respect to intradomain and interdomain are analyzed.
