A survey on congestion control mechanism in multi-hop wireless network

Mobile Ad-Hoc Network (MANET) is an autonomous system of collection of mobile nodes connected by wireless links. Nodes are free to move, frequently change their position and organize themselves into a network. Nodes contain wireless transmitter and receiver that allow them to take part in wireless network. Nodes in MANET having dual behavior, they act as routers as well as computing devices. Limited bandwidth and changing topology results the problem of Congestion in MANETs. Congestion detection is quite difficult in wireless network, because there are several reasons behind packet drop. In mobile networks, unsuccessful delivery could be due to the route breakdown as well because of the mobility of nodes. So congestion is not the only reason for packet losses. The congestion control approaches that are used in wired network cannot be directly applicable in wireless networks. This paper contains a survey on various existing congestion control techniques.
