Balancing communication workloads is a perennial performance issue in the area of Distributed Virtual Environments (DVE). The stringent time constraints of Multiplayer Online Games (MOG) complicate efforts to effectively distribute the networking load amongst servers. This issue becomes ever more exacting, when we move towards a fully Peer-to-peer virtual world (P2P-VE). We are consequently forced...
Most organizations exchange, collect, store and process data over the Internet. Many hospital networks deploy Web services to send and receive patient information. SOAP (Simple Object Access Protocol) is the most usable communication protocol for Web services. XML is the standard encoding language of SOAP messages. However, the major drawback of XML messages is the high network traffic caused by large...
Monitoring of physiological signals of disaster affected patients inherit several challenges. First of all, the care providers of a disaster zone are susceptible to health hazards for themselves. Fast and easy transportation of monitoring equipments is crucial for survival of the injured. Moreover, Enormous physiological data transmission from the disaster zone to the medical server needs to be regulated...
With the advent of high-speed internet bandwidth consuming video conferencing applications will rapidly become attractive to e-patients seeking real-time video consultations from e-doctors. In a conventional system patients connect to a known server in a medical center of his choice. If the server (i.e. a server via which a medical consultant communicates with a patient) is busy, the patient must...
Commercial Content Delivery Networks create their own network of servers around the globe to effectively deliver Web content to the end-users. The peering of Content Delivery Networks (CDN) would increase the efficiency of commercial CDNs. But still the high rental rates resulting from huge infrastructure cost make it inaccessible to medium and low profile clients . Academic models of peer-to-peer...
In cooperative P2P Web caching if the Web cache first receiving a request does not have the document in its memory, it starts searching for it in other nearby cooperating Web caches, retrieving and sending it to the client before contacting the origin (content) server. The advantages of cooperative caching are clear: it reduces the network bandwidth consumption, actual traffic on the origin servers,...
Due to deployment difficulty of network layer multicast, application layer multicast is considered to be a good substitute for massive P2P video/audio streaming in large networks. However, in application layer multicast, the participating users join and leave the on-going session at will. Therefore, a scalable and reliable group membership management algorithm is necessary due to the highly dynamic...
