The power aware routing schemes for mobile ad hoc networks have been developed for increasing network life time by isolating low power nodes from the routing process. This paper presents a survey of some recently proposed power aware routing schemes based on certain characteristics such as multipath support, quality of service support, mobility support and reliability support. It has been learnt that the majority of the proposed power aware routing schemes are not suitable for real-time applications, as they don't support the establishment of multiple simultaneous paths, provision of guaranteed quality of service, and random node mobility. Reliability has also been an important concern in those schemes, which needs to be incorporated in order to find trust aware energy efficient paths.
