An energy efficient routing and MAC protocol for Bridge Monitoring

Wireless sensor networks require protocols which are energy efficient to improve the network lifetime. This work mainly focuses on the cross-layer implementation that takes routing module and MAC module for the required application. At the routing layer unequal clustering is taken, which employe tunable range for cluster radius and eliminates the burden on nodes which are near to base station. At the MAC layer Timeout MAC is taken, which employe dynamic duty cycle that reduces the power consumption of node by making it to go to sleep state. This proposed model for the joint optimization system is tested by simulations in order to quantitatively evaluate the benefits of proposal. Castalia, which is based on OMNeT++ platform is used to evaluate the performance of the proposed protocol.
