Sensor Coverage Strategy in Underwater Wireless Sensor Networks

open access: yesINTERNATIONAL JOURNAL OF COMPUTERS COMMUNICATIONS & CONTROL, 2020
This paper mainly describes studies hydrophone placement strategy in a complex underwater environment model to compute a set of "good" locations where data sampling will be most effective. Throughout this paper it is assumed that a 3-D underwater topographic map of a workspace is given as input.Since the negative gradient direction is the fastest ...

Stochastic Scheduling for Underwater Sensor Networks [PDF]

open access: yes, 2011
The context of underwater sensor networks (UWSNs) presents special challenges for data transmission. For that context, we examine the merit of using a simple, stochastic transmission strategy based on the ALOHA protocol. The strategy uses a stochastic scheduling approach in which time is slotted, and each network node broadcasts according to some ...
