Mobile Ad-hoc Network one of the prominent area for the researchers and practitioners in assorted domains including security, routing, addressing and many others. A Mobile Ad-hoc Network (MANET) refers to an autonomous group or cluster of mobile users that communicate over relatively bandwidth constrained wireless links. Mobile ad hoc network refers to the moving node rather than any fixed infrastructure, act as a mobile router. These mobile routers are responsible for the network mobility. The history of mobile network begin after the invention of 802.11 or WiFi they are mostly used for connecting among themselves and for connecting to the internet via any fixed infrastructure. Vehicles like car, buses and trains equipped with router acts as nested Mobile Ad-hoc Network. Vehicles today consists many embedded devices like build in routers, electronic devices like Sensors PDAs build in GPS, providing internet connection to it gives, information and infotainment to the users. These advances in MANET helps the vehicle to communicate with each other, at the time of emergency like accident, or during climatic changes like snow fall, and at the time of road block, this information will be informed to the nearby vehicles. Now days technologies rising to provide efficiency to MANET users like providing enough storage space, as we all know the cloud computing is the next generation computing paradigm many researches are conducting experiments on Mobile Ad-hoc Network to provide the cloud service securely. This paper attempts to propose and implement the security based algorithmic approach in the mobile adhoc networks.

We are proposing enhancements in one of the most popular data compression algorithm named LZW algorithm to increase overall performance of the algorithm. We have achieved this by applying three modification schemes to LZW algorithm. First two enhancement schemes eliminate the frequent flushing of dictionary, thus lowering processing time and third enhancement improves the compression ratio by reducing number of bits transferred over the communication channel

In spite of various research endeavors, phishing assaults stay common and exceedingly successful in attracting clueless clients to uncover delicate data, including account details and government managed savings numbers. Misfortunes due to phishing are developing consistently. A solitary methodology isn't effective for distinguishing a wide range of phishing assaults. So we propose a hybrid approach to deal with the classification of URLs as phishing or real. The investigation aftereffects of our proposed methodology, in view of a dataset gathered from phishing and legitimate URLs, have demonstrated that PhishAlert framework can successfully counteract phishing assaults and can thus ensure system security.
