Wireless Sensor Networks (WSNs) have been a current trend in the research field and has many issues when there are multiple mobile sinks. Data dissemination gets critical as their locations have to be repeatedly updated and results in huge consumption of the restricted battery supply in sensor nodes. In this paper, we propose GCCP – NS, a grid based congestion control protocol with N -sinks tha...

Pervasive computing provides an attractive vision for the future of computing. Mobile computing devices such as mobile phones together with a land-based and wireless communication network infrastructure are the existing technical prerequisites for continuous access to networked services. The security of the system is a high concern in this environment, as well as its usability. This paper prese...

Grids provide a uniform interface to a collection of heterogeneous, geographically distributed resources. In recent years, the research on the Grid Monitoring System gets increasingly essential and significant. In this paper we put forward a novel Mobile Agent-based Grid Monitoring Architecture (MA-GMA), which is based on the GMA from GGF and introduces the mobile agents and cache mechanism of ...

Smart mobile devices and advanced wireless networks make the vision of pervasive computing come into reality through context aware services. A wireless spatial data broadcasting is a natural way of pervasive information services by providing information related to mobile clients' location context to an arbitrary number of clients. To support location aware information services efficiently, we p...

Mobile electronic devices, such as Personal Digital Assistants (PDAs), Smart Phones, and wearable computers, have limited processing power, battery life and storage space. These restrictions slow application execution and hinder operability. A non-collaborating collection of mobile devices does not optimally use available resources. With a distributed software system, devices could collaborate ...

The increase in the popularity of small digital mobile devices also implies an increased demand in applications. The limited computing capabilities on the mobile devices and the unreliability of wireless links are barriers to the smooth access of mobile devices to the Grid applications and resources. In this paper a proxy-based approach is presented that is able to support various kinds of appl...

According to a survey by Indian Council of Medical Research, an abysmally low number of people living in rural India have access to specialist care and advice. Telemedicine aims to fill up this gap by enabling specialists deliver medical advice to remote areas. The recent advances in broadband technology for mobile phones add new dimensions to telemedicine by facilitating any time, anywhere acc...

Mobile devices are gradually becoming prevalent in our daily life, enabling users in the physical world to interact with the digital world conveniently. Mobile devices increasingly offer functionality beyond the one provided by traditional resources processor, memory and applications. This includes, for example, integrated multimedia equipment, intelligent positioning systems, and different kin...

Wireless mobile grids are one of the emerging grid types, which help to pool the resources of several willing and cooperative mobile devices to resolve a computationally intensive task. The mobile grids exhibit stronger challenges like mobility management of devices, providing transparent access to grid resources, task management and handling of limited resources so that resources are shared ef...

In addition to the capability to navigate from a point of origin to a given goal and avoiding all static and dynamic obstacles, a mobile robot must posses another two competencies: map building and localization in order to be useful. A mobile robot acquires information of its environment via the process of map building. Map building for mobile robots are commonly divided into occupancy grid and...
