Doctrine of Estoppel

The object of every law is to render justice. But sometimes the strict implementation of low may result in injustice. Under such circumstances equity will step in to prevent the injustice. Estoppel is one such concept evolved by equity for rendering justice even deviating from strict legal principles. This study is an analysis of the essence of the principle of estoppel, its scope, circumstances and application. The related principles known as estoppel by record, estoppel by deed, estoppel by representation, promissory estoppel, estoppel against public authority is also considered. Estoppel, originated from the sense of justice, equity and good consciousness has since developed through various judicial pronouncements. Further section 115 of the Evidence Act has statutorily recognized and laid down the principles of estoppel. But Section 115 of the Evidence Act or any other statute does not cover the modern development of estoppel in the form of promissory estoppel.

Cooperative Caching Framework for Mobile Cloud Computing

Due to the advancement in mobile devices and wireless networks mobile cloud computing, which combines mobile computing and cloud computing has gained momentum since 2009. The characteristics of mobile devices and wireless network makes the implementation of mobile cloud computing more complicated than for fixed clouds. This section lists some of the major issues in Mobile Cloud Computing. One of the key issues in mobile cloud computing is the end to end delay in servicing a request. Data caching is one of the techniques widely used in wired and wireless networks to improve data access efficiency. In this paper we explore the possibility of a cooperative caching approach to enhance data access efficiency in mobile cloud computing. The proposed approach is based on cloudlets, one of the architecture designed for mobile cloud computing.
