Security protocols used in today’s communication are complex and it is very difficult to analyze and optimize them. Literature reports some results which optimize security protocols. In the case of devices with limited resources (mobile phones, PDA, sensors) the speed and efficiency of the process is crucial for their stable work. Security methods used during transporting the data between parti...

how does a journalist or an editor decide which news is worthy and which is not? according to some media researchers, they refer to a set of news values. one of the best known lists of such news values have been supplied by johan galtung and marie h. ruge. an analytical discussion on news values always refers to this list, which initially intended to cover international events. these factors i...

Recently, the mobile community has focused on techniques for reducing energy consumption for mobile hosts. These power management techniques typically target communication devices such as wireless network interfaces, aiming to reduce usage, and thus energy consumption , of the particular device itself. We observe that optimization of a single device's energy consumption, without considering the...

Users of mobile computers will soon have online access to a large number of databases via wireless networks. Because of limited bandwidth, wireless communication is more expensive than wire communication. In this paper we present and analyze various static and dynamic data allocation methods. The objective is to optimize the communication cost between a mobile computer and the stationary comput...

Multi-agents systems communication is a technology, which provides a way for multiple interacting intelligent agents to communicate with each other and with environment. Multiple-agent systems are used to solve problems that are difficult for solving by individual agent. Multiple-agent communication technologies can be used for management and organization of computing fog and act as a global, d...

The cellular network is one of the emerging areas of communication, in which the mobile nodes act as member for one base station. The cluster based communication is now an emerging area of wireless cellular multimedia networks. The cluster renders fast communication and also a convenient way to work with connectivity. In our scheme we have proposed an optimization technique for the fuzzy cluste...

Locality of reference is an important aspect of many computer operations. It is often exploited to optimize the performance of computer functions. In this paper, we apply the locality concept to the communication patterns of parallel programs operating over an interconnection network with a fixed communication latency between any pair of attached nodes. Unbuffered multistage networks and all-op...

Emerging low power, embedded, wireless sensor devices are useful for wide range of applications, yet have very limited processing, storage, and especially energy resources. Thus, a key design challenge is to support application-specific optimizations in a highly flexible manner. Power consumption and capabilities of the radio communication layer are the dominant factors in overall system perfor...

Two of the most important aspects in the design of multi-robot systems are the allocation of tasks among the robots and the robots’ communication in a productive and efficient manner. Task allocation methodologies must ensure that not only the global mission is achieved, but also that the tasks are well distributed among the robots. An effective task allocation approach considers the available ...

The Hybrid method of parallelization (using MPI for internode communication and OpenMP for intra-node communication) seems a natural fit for the way most clusters are built today. It is generally expected to help programs run faster due to factors like availability of greater bandwidth for intra-node communication. However, optimizing hybrid applications for maximum speedup is difficult primari...
