CLBR-Co-operative Load Balancing in Robust Duty Cycle MAC Protocol for Energy Efficient WSNs

Abstract - Despite their limited resources, especially energy, wireless sensor networks (WSNs) are being accepted in many application areas. This makes them a challenging yet an appealing research area. Evidently, prolonging network's lifetime is a major focus. It leads to operate the nodes in low power mode. This duty-cycling results in increased network latency. Dynamic adjustment of duty cycle will improve the lifetime of the network. Bandwidth efficiency is another factor which plays an important role in case of high traffic of data and can be better addressed by dynamically distributing the load to other channels. This protocol CLB-RDMAC enhances the RDMAC protocol by incorporating the dynamic load balancing along with duty cycle adjustment. The simulation results show an improvement in the data delivery along with increased lifetime of the network.
