MANETs are infrastructure less and can be set up anytime anywhere. One of the main design constraints in Mobile Ad Hoc NETworks (MANETs) is that they are power constrained. Hence, every effort is to be channeled towards reducing power. More precisely, network lifetime is a key design metric in MANETs. In this kind of network the mobility rate of nodes is high, so excessive use of energy and also switching off of nodes will cut links between nodes.
