Energy minimization has become a burning issue for Wireless Sensor Networks (WSNs) which are mainly event based systems and rely on the collective effort of several micro-sensor nodes continuously observing a physical phenomenon. Energy efficient approaches or tools are the key to prolong the lifetime of the sensor nodes. This paper presents a cross-layer approach between the Medium Access Control (MAC) and the network layer to achieve energy efficiency. Ad-hoc On-demand Distance Vector (AODV) is used here as routing protocol in the network layer along with IEEE-802.11 protocol in the MAC layer.
