With the world turning into a global village due to technological advancements, automation in all aspects of life is gaining momentum. Wireless technologies address everincreasing demands portable and flexible communications. ad-hoc networks, which allow communication between devices without need for any central infrastructure, are significance, particularly monitoring surveillance applications. A relatively new research area networks flying (FANETs), governing autonomous movement unmanned...
Recently, Flying Ad-hoc Networks (FANETs), enabling ad-hoc networking between Unmanned Aerial Vehicles (UAVs) is gaining importance in several military and civilian applications. The sensitivity of the applications requires adaptive; efficient; delay bounded scalable communication network among UAVs for data transmission. Due to protocol complexity; rigidity; cost commercial-off-the-shelf (COT) components; limited radio bandwidth; high mobility computational resources; maintaining desired...
One of the critical parameters Wireless Sensor Networks (WSNs) is node lifetime. There are various methods to increase WSN lifetime, clustering technique being one them. In clustering, selection a desired percentage Cluster Heads (CHs) performed among sensor nodes (SNs). Selected CHs responsible for collecting data from their member nodes, aggregating and finally sending it sink. this paper, we propose Fuzzy-TOPSIS technique, based on multi criteria decision making, choose CH efficiently...
Wireless based sensor networks contain sensors for environment monitoring but have restricted resources. Many clustering protocols are designed to prolong network lifetime problems of inadequate cluster head selection criteria, fixed clustering, and static rounds which consume more energy. It is needed develop an adaptive strategy better CH load balancing. In this article, we introduced energy-efficient mobility mechanism overcome these limitations. on dedicated parameters that a huge impact...
Satellite communication (SATCOM) is crucial for global connectivity, particularly in remote far-flung areas. Typically, these links are established by connecting a Satcom Remote Terminal to Hub Station. However, relying on single Station does not offer redundancy, leaving terminals isolated case of failure. To provide the shifted secondary several limitations and challenges associated with available methodologies shifting remotes This research addresses implementation redundancy/ Disaster...

In reactive routing protocols, active routes for connections retain their topological structure even when node movements over time make the route sub-optimal (in terms of path length). AODV, example, a connection is recomputed only one its constituent links suffers catastrophic failure-at which point repair initiated, often requiring global discovery and introducing significant control traffic overhead. this paper, we propose extensions to AODV perform continuous optimization. The objective...

Training algorithms, broadly construed, are an essential part of every deep learning pipeline. algorithm improvements that speed up training across a wide variety workloads (e.g., better update rules, tuning protocols, rate schedules, or data selection schemes) could save time, computational resources, and lead to better, more accurate, models. Unfortunately, as community, we currently unable reliably identify improvements, even determine the state-of-the-art algorithm. In this work, using...
