A novel method for self management of the energy consumption of nodes dying out of low battery capacity in a NTP based routing environment of MANETs

Abstract

Battery capacity is an important factor that decides the network lifetime. If any node is dying out of low battery capacity then as a consequence there will be dropping of packets. So, it is vital to protect the node from becoming unstable due to reduction in remaining battery capacity. This paper proposes a self management scheme where the node automatically manages its energy consumption thereby saving its battery capacity until its recharge by continuous ‘unstable node’ tracking method at an optimum threshold battery capacity value. This method also rectifies the drawback of the network getting blocked with the help of two methods: either self recovery of nodes or by intelligently adapting to the safest routing point in order to conserve the energy until recharge. The novel ‘unstable node’ tracking method is devised exclusively for Node Transition Probability (NTP) based routing environment and the same technique can be carried over to any protocol by manipulating the corresponding control packets as proposed in the paper. And the intelligent adaptation technique has been extended to universal usage and the performance had been carried out in AODV.
