Routing in MANET has attracted numerous research efforts in the last decade. The MANET routing protocols may be broadly classified into the following four main categories: (1) Reactive – such as Ad-hoc On-demand Distance Vector protocol (AODV) (Perkins et al. 2003), (2) Proactive (Table-driven) – such as Optimized Link State Routing protocol (OLSR) (Clausen et al., 2001), (3) hybrid – such as Zone Routing Protocol (ZRP) (Beijar, 2002), and (4) hierarchical – such as Dynamic Address Routing (DART) (Eriksson et al., 2004). Many existing works however does not explicitly consider energy efficiency in their designs. Few of them have integrated a layer-2 medium access control (MAC) protocol with power-awareness in their design or evaluation.
