In a mobile ad hoc network, the mobility of a node is unpredictable. The mobility is considered as one of the characteristics of a wireless network. In addition, the energy limit of the nodes must also be taken into consideration when designing routing protocols. This is an essential issue since energy consumption reduces the wireless network connection lifetime. In mobile link packet are often more significant than congestion losses. Congestion avoidance results in a very low utilization of the link when there is an appreciable rate of losses due to link errors. This issue is very significant for wireless links.
