Abstract
Previous work on routing in MANETs has resulted innumerous routing protocols that aim at satisfying constraints such asminimum hop or low energy. Existing routing protocols often fail todiscover stable routes between source and sink when route availabilityis transient, i.e., due to mobile devices switching their network cardsinto low-power sleep modes whenever no communication is takingplace. In this thesis, we introduce a new approach stability awaresource routing protocol that is capable of predicting the stability (i.e.,expiration time) of multiple routes. Proposed protocol selects the routethat minimizes hop count while staying available for the expectedduration of packet transmission. The stability aware routing (SAR)resolve the problem of SADSR protocol indicate a significant increasein route discovery success rate with comparable route establishmentand maintenance overheads.

A Mobile Ad-Hoc Network (MANET) is a collection of mobile nodes forming as arbitrary networks without the support of any fixed infrastructure such as base station or access point
A new approach in Stability Aware Routing (SAR) is based on the prediction of future sleep times of mobile nodes
Sleep modes can lead to loss of network connectivity and lower the packet delivery ratio. This paper3 focuses on routing in MANETs with transient route availabilities, i.e., route establishment takes into consideration the expiration time and the stability of a potential route. This new approach is based on the prediction of future sleep times of mobile nodes
Summary
A Mobile Ad-Hoc Network (MANET) is a collection of mobile nodes (such as laptops, PDAs) forming as arbitrary networks without the support of any fixed infrastructure such as base station or access point. Existing routing protocols often fail to discover stable routes between source and sink when route availability is transient, e.g., due to mobile devices switching their network cards into low-power sleep modes whenever no communication is taking place. A new approach in Stability Aware Routing (SAR) is based on the prediction of future sleep times of mobile nodes (i.e., the times when mobile nodes' DPM techniques will turn off their network cards). The goal of this approach is to introduce DPM-awareness in routing decisions and thereby to increase the number of successful packet transmissions
