Md. Imran Hossain Jony, Mohammad Rakibul Islam . Energy Efficient Cross-Layer Approach for Wireless Sensor Networks. International Journal of Computer Applications. 127, 10 ( October 2015), 31-37. DOI=10.5120/ijca2015906519
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. Simulation results show that cross-layer approach obtains significant energy savings compared with traditional approaches.
