Routing cost versus network stability in MANET

Recent MANET routing protocols minimize power cost because of the battery power limitation of participating mobile devices but may result in network disconnection. On the other hand lifetime prediction based algorithms help to maintain network stability with a cost penalty. In this paper we show how cost effective routing protocols affect network stability of MANET. We also find a tradeoff between routing cost and network stability to get overall best performance. The simulation results show that our proposed scheme needs less cost than in lifetime prediction based routing algorithms and results in a more stable network than cost-effective routing algorithms.
