Coruscations and Requirements for Quality of Services in Mobile Ad hoc Networks

A mobile Ad hoc network (MANET) is an autonomous system of mobile routers (and associated hosts) connected by wireless links. In some applications, the routers are fixed and sometimes mobile free to move randomly and organize themselves arbitrarily. Due to mobile nature, the network’s wireless topology may change rapidly and unpredictably. Such a network may operate in a stand-alone fashion, or may be connected to the larger Internet. MANET’S were initially proposed for use in military and battle field, due to the rapid expansion of the Multimedia Technology, Mobile Technology and civilian applications has to strictly adhere to QoS. The paper presents the description about the QoS and the issues of MANETS like Routing, Medium (or Channel) access, Mobility Management, Security and Reliability, and Power Consumption and also the current approaches including models and solution strategies. The paper presents a literature study on the requirements of Quality of Services (QoS) in Mobile Ad-Hoc Networks (MANET’S) which is universally growing area.
