Abstract

It is important to provide energy-balanced routing protocols, since a critical limiting factor for a mobile host is its operation time, which is restricted by its battery capacity. We propose a scheme in which each mobile host maintains an energy tree and uses it to evaluate the amount of energy remaining in other mobile hosts. Our proposed algorithm extends the lifetime and upgrades the performance of the system, in that the amount of energy consumed by each mobile host in wireless ad-hoc network is balanced, thereby prolonging the lifetime of those mobile hosts whose energy capacity is limited.
