In this paper, we propose an algorithm to alleviate coverage hole problem using geographic routing strategy for wireless sensor networks (WSNs). In order to accomplish desired results, an optimal number of forwarder nodes is computed along with the selection of path that has minimum energy consumption. Moreover, at each hop residual energy of a sensor is calculated and knowledge up-to one hop neighbors...
In this paper, we exploit cooperative communication for designing an energy-efficient routing algorithm in underwater wireless sensor networks (UWSNs). Each network node is equipped with a single omnidirectional antenna and multiple node coordinates while taking advantage of spatial diversity. This research work is limited in scope to amplify-and-forward (AF) scheme at the relay node and fixed ratio...
For the design of a network layer routing scheme for Underwater Wireless Sensor Network (UWSN), physical layer cooperation is used in this paper which ensures energy efficiency. For achieving major goal of efficient data routing, a key factor is reliability for application-oriented UWSNs. All the nodes of network fortified by a unidirectional antenna cooperatively perform their propagation of data...
