Project Details ₹600.00 – 1,500.00 INR Bidding ends in 6 days, 22 hours Project Scope We would like to proceed with the prototype development of the SoilKare Agricultural Monitoring & Crop Quality Device as described in the engineering specification document we shared earlier. The system includes the following main subsystems: • STM32-based embedded controller • LTE communication module (SIM7600 or equivalent) • Soil monitoring sensors (pH, EC, moisture, temperature) • Water quality sensors (pH, EC/TDS, temperature) • Crop / leaf health sensors (chlorophyll / multispectral sensor) • Agricultural produce quality testing sensors (Brix, nitrate, crop moisture) • External ADC interface (ADS1115 or similar) • RS-485 interface for ind...

Project Overview Designed and implemented an intelligent DDoS detection and mitigation framework for Software-Defined Networking (SDN) based Vehicular Ad-hoc Networks (VANETs) to ensure secure, reliable, and low-latency vehicle-to-infrastructure (V2I) communication. The system leverages SDN’s centralized control to dynamically monitor network traffic and mitigate DDoS attacks in real time, ensuring uninterrupted safety-critical vehicular services. Key Innovations: SDN-Based Centralized Security Control OpenFlow-enabled SDN controller Global view of VANET traffic behavior Intelligent DDoS Detection Flow-level traffic analysis Anomaly detection using ML / Deep Learning (LSTM Autoencoder / Hybrid model) Real-Time Mitigation Strategy Malicious vehicle flow isolation Dynamic ru...

I need a complete technical design that shows how 280 individual water meters, each fitted with an RS485-enabled shut-off valve, can be wired, networked, and surfaced in a single cloud dashboard for a large residential complex. Scope • Network architecture – segmenting the 280 devices into practical RS485 loops, recommended cable types, addressing scheme, surge/grounding considerations, and maximum run lengths. • Gateway selection – please evaluate and recommend a commercially available RS485-to-Ethernet/LTE gateway (no brand preference yet) that can reliably push data to the cloud and withstand a residential plant room environment. • Cloud layer – outline the server or IoT platform setup that will provide real-time consumption graphs, manual/automatic...

ALFA NETWORKS ADAPTOR OR SIMILAR IS A REQUIREMENT I need a cyber sec expert who already owns an Alfa Networks USB adapter (or a comparable injection-capable card) to carry out a controlled WiFi-based denial-of-service exercise. The goal is to you use the Kali Live boot with persistence USB stick, and the Alfa Networks adaptor, to launch a Denial-of-Service attack on your own mobile phone (or smart TV etc) in order to prevent it accessing your home WiFi. its just a simulation so we only need 4 screenshots. I ordered my alfa networks adaptor but it got delayed with the shipment so now need help if you own one. ALFA NETWORKS ADAPTOR OR SIMILAR IS A REQUIREMENT
