A Secure Routing Algorithm for Underwater Wireless Sensor Networks
Recently, underwater Wireless Sensor Networks (UWSNs) attracted the interest of many researchers and the past three decades have held the rapid progress of underwater acoustic communication. One of the major problems in UWSNs is how to transfer data from the mobile node to the base stations and choosing the optimized route for data transmission. Secure routing in UWSNs is necessary for packet d...
متن کاملmac protocols in underwater wireless sensor networks: issues and simulations
underwater acoustic wireless sensor network (uawsn) use acoustic signalsto transmit data. acoustic signals in underwater environment have high bit errorrate, long propagation delay and limited bandwidth. another constraint in uwasnis energy. due to these constraints, design of energy and bandwidth efficient andpropagation delay aware mac protocol is a great challenge in uwasn.underwater sensor ...
متن کاملAnalyzing Multi-channel MAC Protocols for Underwater Acoustic Sensor Networks
The focus of this paper is on the multi-channel MAC protocols for underwater acoustic sensor networks. We model and analyze two generalized multi-channel MAC protocols: multi-channel access with Aloha on a dedicated control channel and multi-channel access with RTS/CTS on a dedicated control channel. Though the long delay feature of underwater acoustic channels drastically increases the complex...
متن کاملAnalyzing Routing Protocols for Underwater Wireless Sensor Networks
Underwater sensor networks (UWSN) resemble terrestrial sensor networks in many aspects. However, the high propagation delay and limited bandwidth make terrestrial sensor network’s protocols unsuitable for UWSN. For instance, routing protocols proposed for terrestrial networks are not applicable in an underwater network. Therefore, enormous efforts have been made for designing efficient protocol...
