Underwater sensor networks are envisioned to enable a broad category of underwater applications such as pollution tracking, offshore exploration, and oil spilling. Such applications require precise location information as otherwise the sensed data might be meaningless. On the other hand, security critical issue as underwater sensor networks are typically deployed in harsh environments. Localiza...

Recently, Underwater Sensor Networks (UWSNs) have attracted researchers’ attention due to the challenges and the peculiar characteristics of the underwater environment. The initial random deployment of UWSN where sensors are scattered over the area via planes or ships is inefficient, and it doesn’t achieve full coverage nor maintain network connectivity. Moreover, energy efficiency in underwate...

In particular, the problem of supporting f...

This paper addresses distributed multi-target tracking over a network of sensors having different fields-of-view (FoVs). Specifically, cardinalized probability hypothesis density (CPHD) filter is run at each sensor node. Due to the fact that node has limited FoV, standard fusion methods need be suitably modified. In fact, monitored area multiple nodes consists several parts are either exclusive...

Routing is a critical function in adhoc network which claim special attention and support extended by the trustable neighbor nodes. The peril of Gratuitous detour on routing process in ad hoc network is manifold which culminates in the deterioration of network performance amounting to deplorable network behavior. Routing in ad hoc network is a cooperative process as it requires periodic assista...

For event dynamic K-coverage algorithms, each management node selects its assistant node by using a greedy algorithm without considering the residual energy and situations in which a node is selected by several events. This approach affects network energy consumption and balance. Therefore, this study proposes a distributed and energy-efficient event K-coverage algorithm (DEEKA). After the netw...

This paper develops and compares different sensor network architecture designs that can be used for monitoring underwater pipeline infrastructures. These architectures are underwater wired sensor networks, underwater acoustic wireless sensor networks, RF (radio frequency) wireless sensor networks, integrated wired/acoustic wireless sensor networks, and integrated wired/RF wireless sensor networ...

Underwater environments are quite different from terrestrial environments in terms of the communication media and operating conditions associated with those environments. In underwater sensor networks, the probability of node failure is high because sensor nodes are deployed in harsher environments than ground-based networks. The sensor nodes are surrounded by salt water and moved around by wav...
