Sleep Scheduling for Energy Efficient Load Balance Routing in Heterogeneous Wireless Sensor Network

In energy constrained Wireless Sensor Networks (WSNs) is very important to preserve energy and prolong energetic network lifetime while ensuring the proper operation of the network. In this paper we propose Sleep Scheduling for Energy Efficient Load Balance Routing in Heterogeneous Wireless Sensor Network (EE_LBR) to extend the lifetime of the network. The Sleep and awake scheduling utilized for reduce the energy consumption in the network. We also using Queue Priority Indicator (QPI) and Geographic Priority Indicator (GPI) are used to select the best relay node and find the efficient path. The QPI method is used the balance load and energy consumption. The Network simulation based performance evaluation shows that the EE_LBR scheme to minimize the packet loss rate and energy consumption as well as increase the lifetime of the network and throughput.
