Reposition Scheme of improving quality of server in Heterogeneous Wireless Sensor Networks
Reducing power consumption, improving quality of server and prolonging the network lifetime were important targets of wireless sensor networks. So an Energy Preserving Reposition (EPR) algorithm based on Heterogeneous Wireless Sensor Networks was proposed. The need for repositioning of the Principal Node (PN) is emphasized in terms of energy and other QoS parameters such as latency and throughput. EPR is to pursue relocation of PN to a safe location on demand. EPR performs reposition based on the minimum energy concept of sensor nodes. The simulation results illustrated that this algorithm had better load balance between nodes, prolongs the stability period and lifetime of networks and increased the efficiency of the communication in the whole network system.
