This paper focuses on the simple radio frequency transceiver model of the sensor node. We have combined the effect of realistic analytical model with the HEED and H-HEED protocol for wireless sensor network. Under this impact, the performances of the HEED and H-HEED protocol have been evaluated.
Wireless Sensor Network (WSN) consists of small nodes with sensing, computation, and communications capabilities. Sensor node senses the data and sends data to the base station for further processing. These sensor nodes mainly rely upon batteries for energy, which get drained at a quicker rate due to the computation and communication and this decreases the lifetime of the network. In order to solve...
Directional Sensor Network (DSNs) being a subdivision of WSN has attracted researchers a lot due to its wide deployment in visual monitoring applications as the continuous technical advancements have enabled us making use of low-cost camera sensors.

The IEEE INFOCOM community has looked to large-scale computer networking testbeds such as PlanetLab, Emulab, and ORBIT to fulfill an essential role in the testing and validation of innovative ideas. Until very recently, testbeds such as these have existed in separate silos, each with its own authentication mechanisms and experiment support tools. The OneLab experimental facility breaks down the barriers...
Mobile ferries are an alternative way for collecting data from dispersed sensor nodes especially in large-scale networks. Unlike data collection via multi-hop forwarding among the nodes, ferries travel across the sensing field and collect data from the sensing nodes. The advantage of using a ferry based approach is that, it eliminates the need for multi-hop forwarding of data, and as a result energy...

This paper proposes an underwater positioning system (UPS) for remotely operated underwater vehicle (ROV). The system uses two underwater speakers as anchor nodes and a hydrophone as a receiver node. Time-of-arrival (ToA) is locally measured by sensors to identify distances from the hydrophone to the two anchor nodes. Then, using 2-D trilateration algorithm and depth from a pressure sensor, the position...
Any decentralized, distributed network isvulnerable to the Sybil attack wherein a malicious node masquerade as several different nodes, called Sybil nodes disrupting the proper functioning of the network. A Sybil attacker can create more than one identity on a single physical device in order to launch a coordinated attack on the network or can switch identities in order to weaken the detection process,...
In wireless sensor networks, communication cost is higher as compared to computational cost, so it is important to minimize the amount of data transmission to extend the network lifetime. To minimize the volume of data to be transmitted, data aggregation is mostly used. As sensor nodes are being deployed in remote and unattented environments, they are prone to node compromise attacks and various other...
