In underwater sensor networks (UWSNs), information transmission is extremely challenging because of the underwater channel. Underwater acoustic channel suffers from long propagation delay and low bandwidth is inclined to packet losses. Hence, the design of an energy efficient communication system is challenging under the water. In this paper, we present an energy efficient clustered multi-hop routing...
Nowadays in wireless network the energy consumption and sensor node energy renewable is major challenge. Which make sensor network weak and more critical. The problem of node reachability is considered and Amended Ant colony optimization technique is proposed for optimization. The proposed technique is used for the search of estimated solutions to distinct and endless optimization problems and for...
In geographical network systems, face routing is the unique recovery solution for local minimum problem. A node in local minimum could not choose its neighbor node closer to the destination. Since the face routing is based on novel graph named planar graph, the nodes search a link between adjacent nodes in the graph and send their data via the link. During the planarization of the topology, many links...
The limited battery supply of a sensor node is one of the most important factors that limit the lifetime of the WSNs. As a consequence, increasing the lifetime of WSNs through energy efficient mechanisms has become a challenging research area. Previous studies have shown that instead of implementing direct transmission or multi-hop routing, clustering can significantly improve the total energy dissipation...
Wireless Sensor Networks consist of sensor nodes with wireless communication devices and sink nodes (here-inafter referred to as destination nodes). Intermediate nodes relay the source nodes' data packets to destination nodes. When an intermediate node steals a source node's ID within relayed data packets, it can impersonate the source node. In this paper, we have proposed a new detection method against...
This paper explores the attributes, layering models and objective functions in cross layer designs for mobile ad hoc wireless networks by taking all the statistical characteristics and constraints from the physical (PHY) layer, media access control (MAC) layer and network (NET) layer into consideration. This paper reviews the entire network optimization across all the PHY/MAC/NET layers. At the PHY...
