Reliable efficient cluster routing protocol based HTDE scheme for UWSN

<p>Underwater sensor networks (UWSNs) are recently recognized as a promising method for monitoring and exploring the underwater environment. Due to real-time remote data requirements, UWSN has become preferred network large extent. But reliable efficient secure transmission receiver is one of most important challenges UWSNs, often suffer from irreplaceable batteries high latency long-distance communications. The challenging task extending life, shortening distances each node. Thus, this paper presents cluster routing (RECR) protocol, optimal shortest path finding (OSPF) algorithm hill transformation encryption (HTDE) UWSNs. proposed encrypts source node, RECR protocol used delivery destination. To extend network's employs autonomous vehicle (AUV) sink node (SN) collection. OSPF find avoid latency. HTDE enhance efficiency, minimizing energy consumption improves life time. decreases end-to-end latency, packet loss.</p>
