Billions of objects connect to the internet by using Internet of Things (IoT). Current trends of IoT are developing protocols, platforms make objects accessible across domains. The purpose of these studies is to combine all IoT devices on main host systems. However, the host systems have a problem about the mismatch between devices and the host. To solve this problem we have designed the Information...
Vehicular adhoc networks come out to be a promising solution for ensuring traffic and road safety on highways. However this area induces communication challenges such as topology dynamics, and connectivity losses. Today's Vanet demand a sound planning to make architectural level decisions. Integrating Vanet with emerging Software defined Networking brings ground-breaking networking innovation. Recent...
Underwater environment suffers from a number of impairments which effect reliability and integrity of data being transmitted. Cooperative transmission is well known for reliable data transfer. Hence, cooperative routing can be implemented in Underwater Wireless Sensor Networks (UWSNs) in order to reduce the impact of existing link impairments on transmitted data. Cooperative routing involves data...
Design and development of adaptive, scalable and energy-efficient routing protocols for Wireless Sensor Networks (WSNs) is an active area of research. Many protocols and techniques have been proposed and implemented for energy efficient routing. In this research work, we present Bio inspired Distributed Energy Efficient Clustering (B-DEEC) protocol for WSNs. It is based upon Artificial Bee Colony...
Optimal utilization of resources in present-day communication networks is a challenging task. Routing plays an important role in achieving optimal resource utilization. The open shortest path first (OSPF) routing protocol is widely used for routing packets from a source node to a destination node. This protocol assigns weights (or costs) to the links of a network. These weights are used to determine...
Cluster based routing technique is most popular routing technique in Wireless Sensor Networks (WSNs). Due to varying need of WSN applications efficient energy utilization in routing protocols is still a potential area of research. In this research work we introduced a new energy efficient cluster based routing technique. In this technique we tried to overcome the problem of coverage hole and energy...
In this paper, we evaluate and analyze the impact of different network loads and varying no. of nodes on distance vector and link state routing algorithms. We select three well known proactive protocols; Destination Sequenced Distance Vector (DSDV) operates on distance vector routing, while Fish-eye State Routing (FSR) and Optimized Link State Routing (OLSR) protocols are based on link state routing...
In case of high dynamic topology, reactive routing protocols provide quick convergence by faster route discoveries and route maintenance. Frequent broadcasts reduce routing efficiency in terms of broadcast cost; Bk, and expected time cost; E[t]. These costs are optimized using different mechanisms. So, we select three reactive routing protocols; Ad-hoc On-demand Distance Vector (AODV), Dynamic Source...
In this paper, we compare and analyze performance of five quality link metrics for Wireless Multi-hop Networks (WMhNs). The metrics are based on loss probability measurements; ETX, ETT, InvETX, ML and MD, in a distance vector routing protocol; DSDV. Among these selected metrics, we have implemented ML, MD, InvETX and ETT in DSDV which are previously implemented with different protocols; ML, MD, InvETX...
Random Access Scan, which addresses individual flip-flops in a design using a memory array like row and column decoder architecture, has recently attracted widespread attention, due to its potential for lower test application time, test data volume and test power dissipation when compared to traditional Serial Scan. This is because typically only a very limited number of random "care" bits...
In many network and IT systems, users submit loosely-defined (or fuzzy) requests to obtain answers, solutions or resources. In this paper, we focus on trouble-shooting problem tickets in an IT service management system. In such a system, problems are typically reported using vague user-generated descriptions of the symptoms (e.g., 'my email is not working!') in a ticket. IT Specialists are then responsible...
The ability to effectively communicate underwater has numerous applications, such as oceanographic data collection, pollution monitoring, disaster prevention, assisted navigation, tactical surveillance applications, and exploration of natural underwater sea resources. In this paper, we have developed a completely decentralized ad-hoc wireless sensor network for the ocean pollution detection. We mainly...
