Image Transmission Scheme with Joint Routing and HWT-based Compression in Wireless Sensor Networks

Abstract

The network topology one of the most important techniques has been used to reduce energy consumption and increase prolong lifetime of WSN. Reduce packet size before transmitting is another important technique to increase prolong lifetime of WSN. From this perspective, this paper study and analysis routing protocols under different network topology and compressed method. Theoretical analysis and experimental results show that our CPF protocol and compressed method are superior to several earlier network topology protocols for extending network lifetime. The simulation results show significantly enhancement in: the big gap in the network has been gone; the number of died nodes reduced so much, which means increase network life time; maintain on network connectivity even with nodes died; 66% of died nodes have been reduced. This study has been applied with number of different network topology and with different standard pictures. Also, the result shows that our two methodologies regarding to CPF protocol and compressed method produce better connectivity and less died nodes if they are compared with the previous experiments.
