Abstract There has been a lot of improvement in energy savings in wireless sensor networks (WSNs) resulting in increased lifespan of sensor nodes. Consequently, WSNs has gained its widespread use in various fields like medical services, security, home automation, environmental monitoring, and lot more. However, gaining successes leads to extensive acceptance of WSNs particularly at the places where human beings cannot reach. Being most acceptable, it still faces number of challenges like: battery constraint, low speed communication and harsh environment. Many researchers have come up with innovative ideas or energy management approaches to prolong the lifetime of hungry sensor nodes and to make the network more reliable and operational. In this paper, the CLB (Charging with Load Balancing) scheme is firstly proposed based on Laser power Beaming (LPB,) then it is implemented on various modulation schemes to test the optimum and robust

1 Introduction Wireless Sensor Network (WSN) has seen a remarkable development in the past few years. Nowadays, wide range of applications is based on WSNs such as: military applications, healthcare applications, agriculture and many more. The wireless sensor nodes operates on the battery that has a capacity to sense the data, store and then share the same with other nodes in a network. However, battery limitation restricts the researcher to use the sensor nodes at place of deployment for long time. Thus, optimum utilization of sensor’s battery is vital to minimize the consumption of energy. These sensor nodes make use of various optimization methods to overcome rapid depletion issue. One example of optimization method is to switch the node from its active state to sleep mode when the communication no longer exist. This process of saving the energy is known as energy conservation because by doing so, maximum energy can be significantly saved as the power consumption during communication is
