Chapter
Underwater wireless sensor networks (UWSNs) are capable of providing facilities for the wide range of aquatic applications. However, due to the adverse environment, UWSNs face huge challenges and issues i.e., limited bandwidth, node mobility, higher propagation delay, high manufacturer and deployment costs etc. In this paper, we propose two techniq...

With the passage of time, the scope of freelancing is increasing and so many people tend to prefer freelancing over a permanent job due to the ease it offers. Freelancing is helpful in earning additional money without going through the social biasness which is common in traditional organizational environment. In this paper, we performed a systemati...

Due to the limited availability of battery power of the acoustic node, an efficient utilization is desired. Additionally, the aquatic environment is harsh; therefore, the battery cannot be replaced, which leaves the network prone to sudden failures. Thus, an efficient node battery dissipation is required to prolong the network lifespan and optimize...

Conference Paper
Underwater Wireless Sensor Networks (UWSNs) have been considered as an emerging and promising method for exploring and monitoring deep ocean. UWSNs face many challenges due to harsh underwater environment such as noise, high transmission delays, high deployment cost, movement of nodes, energy constraints, etc. In UWSNs nodes are mostly sparsely and...
Chapter
Underwater Acoustic Sensor Networks (UASNs) have gained interest of many researches due to its challenges like long propagation delay, high bit error rate, limited battery power and bandwidth. Node mobility and the uneven load distribution of sensor nodes results in creation of void holes in UASNs. Avoiding void holes benefits better coverage over...
Chapter
Underwater wireless sensor networks (UWSNs) find applications in various aspect of life like the tsunami and earthquake monitoring, pollution monitoring, ocean surveillance for defense strategies, seismic monitoring, equipment monitoring etc. The sensor node consumes more energy and load distribution suffer from imbalance at long distance. In this...

Underwater Wireless Sensor Networks (UWSNs) have been considered as an emerging and promising method for exploring and monitoring deep ocean. The UWSNs face many challenges due to high transmission delays, high deployment cost, movement of nodes, energy constraints, etc. In UWSNs nodes are sparsely and unevenly deployed, that may results in void ho...
Conference Paper
Energy conservation is one of the most important factors in Wireless Sensor Networks (WSNs) for reliability since nodes have limited resources of energy. There is a need to design such routing protocols, which efficiently use available energy and prolong network lifetime and stability period. We implement sink mobility in Clusterless Stable Electio...
Article
Sink Mobility is becoming popular due to excellent load balancing between nodes and ultimately resulting in prolonged network lifetime and throughput. A major challenge is to provide reliable and energy-efficient operations are to be taken into consideration for differentmobility patterns of sink. Aim of this paper is lifetime maximization of Delay...

Moving Sink (MS) in Wireless Sensor Networks (WSNs) has appeared as a blessing because it collects data directly from the nodes where the concept of relay nodes is becomes obsolete. There are, however, a few challenges to be taken care of, like data delay tolerance and trajectory of MS which is NP-hard. In our proposed scheme, we divide the square...
Article
Wireless Sensor Networks (WSNs) are increasing to handle complex situations and functions. In these networks some of the nodes become Cluster Heads (CHs) which are responsible to aggregate data of from cluster members and transmit it to Base Stations (BS). Those clustering techniques which are designed for homogenous network are not enough efficien...
