Energy efficient CLB approach to find optimum modulation scheme in wireless rechargeable sensor networks

摘要

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 modulation type for Wireless Rechargeable Sensor Networks (WRSNs).
