Design an efficient protocol for secured energy efficient routing in large scale wireless sensor networks
Wireless Sensor Network has played a significant role in enabling communication and connectivity to human unreachable area since more than a last decade. Apart from its newlinebeneficial features, it also suffers from various problems that have yet not been solved till date in spite of massive research work in this area. The proposed work jointly addresses the problems of energy efficiency and secure routing in wireless sensor network. The existing literatures are found to provide a less scope of an effective solution to address such issues jointly. Hence, the prime goal of the proposed work is to introduce a mechanism that uses lightweight cryptosystem as a part of new hierarchical routing protocol. The mechanism of the proposed work is discussed in three different modules. Where each module is enhanced version of the previous module. The first module is named as Secured Tree Based Routing with Energy Efficiency (STREE), which newlineintroduces a new energy efficient selection of cluster head along with a very simple and newlinelightweight encryption mechanism for routing message using keccak, a newly launched newlinecryptographic hash function. The second module is named as Secured Authentication Based Routing (SABR) introduces node-to-node authentication along with identification newlineand compensation of network related delay owing to incorporated cryptography. The newlinethird module is named as Secured Anonymous Routing with Digital Signature (SARDS) newlinewhich introduces a distinct mechanism of using enhanced elliptical curve cryptography newlineand a new usage of digital signature. The modelling of proposed study is done using newlineanalytical research methodology and the outcome of the study has been compared with newlineexisting standard routing protocol SecLeach to find that proposed system presents a newlinesuperior mechanism of balancing security, energy efficiency, and communication newlineperformance in wireless sensor network.
