The novel coronavirus or officially known as SARS-CoV 2 (Severe Acute Respiratory Syndrome Coronavirus 2) has caused a severe pandemic over the world affecting not only the economy of the countries but also the lifestyle of the people worldwide. As on 31.12.2020, Covid-19 (coronavirus disease) has infecting more than 10266674 people and causing about 148738 deaths in India. It has been seen through various statistics of various countries that the number of Covid-19 cases grows exponentially as the number of test increases then after some period, the rate of new cases decreases. In this research paper, researchers have created deep learning-based model to predict the curve of the new Covid-19 cases vs the total number of tests conducted in India. There is still lockdown in some part of the country while some states have partially relaxed the rules and some states totally lifted the lockdown. Predicting the number of new cases and their trend can help in deciding what is the optimal time to release the lockdown. It will also help in determining when the coronavirus will loosen its grip from India.

Routing in MANET (Mobile Ad hoc Network) is a challenging task because of the mobile nature of the nodes in a network and topology changes very often and developing effective routing protocols for MANET is also a highly challenging task. To fulfil the multiple routing requirements as low control overhead, low packet delay, high packet delivery rate and adapting effectively to network topology changes and so on, are the issues which are emerging. Amidst lots of problems which are found to be NP-hard in routing, new ways to find approximate solutions have to be investigated. A lot of attention was attracted by Swarm intelligence inspired algorithms which are based on the Ant Colony Optimization meta heuristic technique because they can offer optimized solutions ensuring low control overhead, robustness etc. and presents framework for approximating solutions to NP-hard problems. This paper includes 1) Introducing the ACO technique and its principles 2) Various ACO based routing protocols 3) summary and conclusion.
