Energy is one of the most precious resource in Wireless Sensor Networks (WSNs) which is mainly consumed in communication, sensing and processing. Performance evaluation of WSN routing protocols primarily rely on simulation-based studies. Most of these studies only assume oversimplified First Order Radio Model (FORM) and ignore node's energy consumed in sensing and processing. This paper presents an...
In this paper, we propose an optimization scheme for avoiding void zone and minimization of uncertainty in glider's position estimation. Gliders stay at sojourn positions for predefined time. At these stops, self-confidence (s-confidence) and neighbor-confidence (n-confidence) regions are estimated. On the basis of present state of glider, it estimates s-confidence region and share control information...
Due to unique characteristics of underwater environment, it is difficult to achieve energy efficiency, high throughput and low bit error rate. Radio signals do not propagate well in underwater environment so acoustic signals are used for communication. Acoustic signals offer low bandwidth, high bit error rate, low throughput and high end-to-end delay. Data packets often loose their path which effect...

It is designed on the bases of two bioinspiredalgorithms, genetic algorithm (GA), bacterial...
Impairments of the acoustic channel impose the requirement of improvement in throughput efficiency of the network. Therefore, efficient mechanisms must be proposed to increase throughput while conserving energy at the same time. In this paper, we propose two energy efficient geographic opportunistic routing protocols for underwater wireless sensor networks called improved Distributed Topology Control...
In this paper, we have proposed a two-tiered wireless sensor network (WSN) in which sensor nodes transmit data packets to their connected relay nodes (cluster heads). Each sensor node is associated with at least one relay node in the network. The proposed strategy determines the best set of relay nodes for upper-tier communication. These relay nodes are periodically reselected on the basis of residual...
In this paper, we propose a routing protocol AVN-AHH-VBF for underwater wireless sensor networks (UWSNs). Sensor nodes forward data packets in multi-hop fashion within a virtual pipeline. As nodes outside pipeline do not forward data packets, thus, flooding is avoided in the network. Mitigating flooding in network, in turn, decreases energy consumption and improves delivery ratio. Moreover, on each...
In this paper, we propose a reliable and interference-aware routing protocol for underwater wireless sensor networks (UWSNs). Proposed protocol follows end-to-end path from source node to sink and selects next forwarder node of a data packet on the basis, having already established a path to sink. In this way, the problem of encounters void hole in depth based routing protocol is eliminated. Furthermore,...
Developing an energy efficient routing protocol for underwater wireless sensor networks (UWSNs) is a challenging task due to long propagation delay, low bandwidth, high error probability, and most importantly limited energy. Unlike ter-restrial sensor networks, UWSN environment is harsh. Nodes are provided with limited energy. The replacement or charging of batteries is not an easy task. By minimizing...
In this paper, we propose Geographic and Opportunistic Clustering (GOC) protocol for Underwater Wireless Sensor Networks. GOC is an improved version of Geographic and Opportunistic Routing for UWSNs (GEDAR). GOC uses a hybrid system in which the recovery algorithm of GEDAR is implemented alongside the clustering approach depending on the neighbor list of the void node. Similar to the architecture...
The acoustic environment suffers from a number of impairments which effect transmitted data reliability and integrity leads toward low-quality routing. Integral part of cooperative routing is reliable data delivery with trade-off energy consumption is high, because of multiple transmissions. In order to overcome this problem and getting advantage of cooperation routing, we proposed a scheme Sink Mobility...
Smart grid is one of the most advanced technologies which plays a key role in maintaining balance between demand and supply by implementing demand response (DR). Residential users basically effect the overall performance of traditional grid due to maximum requirement of their energy demand. Home energy management (HEM) benefit the end user by monitoring, managing and controlling their energy consumption...

In this paper, we propose depth and reliability aware delay sensitive (DRADS) routing protocol for underwater wireless sensor networks (UWSNs). We take motivation from underwater opportunistic routing (UWOR) protocol which introduces a new E E L|success (Fi) metric, i.e., the expected end-to-end latency from sender node i to sink. We consider two flaws in UWOR. First, in UWOR protocol, sensor node...
Today, energy is the most valuable resource, new methods and techniques are being discovered to fulfill the demand of energy. However, energy demand growth causes a serious energy crisis, especially when demand is comparatively high and creates the peak load. This problem can be handled by integrating Demand Side Management (DSM) with traditional Smart Grid (SG) through two way communication between...
