Hybrid Multilayer Receiver based MAC Protocol for Green Wireless Sensor Networks

Traditional Wireless sensor networks rely on a limited energy source, mostly batteries. But most applications need nodes to be an autonomous and continuous operation for months or years. Power consumption by sensor node is the most important part of WSN. MAC protocols help in reduction of power consumption which increases the node lifetime. But it can extend the lifetime to a certain point only, finally, we have to replace the battery. Energy harvesting along with the duty cycling come to the rescue, but now the MAC layer needs to be redesigned. In battery-based WSN the major emphasis is on lifetime only but Green Energy harvesting based protocol focus on effective energy utilization and improving the quality of the network. In this paper, new MAC protocol is designed known as Hybrid multilayer receiver initiated MAC protocol customized for the solar energy.
