Energy-Aware Architecture for Wireless Ad Hoc Networks

Abstract

Wireless Ad Hoc networking is a developing new field in technology; that is widely spread in a variety of civil and military applications. Ad Hoc network means a group of mobile terminals connected together wirelessly, and free to move in a bounded area. The battery life of those terminals is limited, therefore the energy efficiency of mobile terminal becomes an important consideration for mobile Ad Hoc wireless networks. Determining a power conservation protocol that minimizes the power consumption, will help the designer of such networks to design more efficient networks with longer life time. This paper presents a simulation study of sleep/ wake up, power save protocol (Modified Multilevel power save protocol MM3) based on IEEE 802.11b standard protocol. This protocol conducted to save more power with the acceptable network performance compared with earlier work; standard IEEE 802.11 power save mode (PSM) and two levels of multi-level power save protocols.
