Mobile ad hoc networks (MANETs) have dynamic irregular topologies by nature, and suffer from inherent limitations such as limited bandwidth and power. A number of routing protocols have been proposed in the past few years to deal with these issues efficiently. The paper proposes and evaluates a new routing protocol, referred to here as the vector routing(More)
There has been a lot of research effort on developing reactive routing algorithms for mobile ad hoc networks (MANETs) over the past few years. Most of these algorithms consider finding the shortest path from source to destination in building a route. However, this can lead to some network nodes being more overloaded than the others. In MANETs resources,(More)
Cloud computing is a very useful solution to many individual users and organizations. It can provide many services based on different needs and requirements. However, there are many issues related to the user data that need to be addressed when using cloud computing. Among the most important issues are: data ownership, data privacy, and storage. The users(More)
In this paper, we propose a new DES variant named Hashed Data Encryption Standard (or HDES for short), with an objective to enhance the limitation of static S-boxes arrangement in DES. The proposed HDES combines several techniques and components into one new algorithm to enhance the original DES. The HDES uses a hash function at the beginning of each block(More)
