Due to exponential requests of users for accessing Internet wireless services, longer delays can incur in full filling requests. So optimizations for delay is required. One such method is using cache and storing frequently accessed pages in local cache. Consistency in cache and server data becomes a major issue. As if cache is not valid then whole optimization will be lost. Many researches have strong...
With an increase in the number of mobile applications, the development of mobile crowdsensing systems has recently attracted a significant attention in both academic researchers and industries. In mobile crowdsensing system, the remote cloud (or back-end server) harvests all the crowdsensing data from the mobile devices, and the crowdsensing data can be uploaded immediately via 3G/4G. To reduce the...
The strong potentials that exist in Vehicular Ad hoc Networks (VANETs) has given birth to the concept of Vehicular Clouds, in which cloud computing services are hosted by vehicles that have sufficient resources to act as mobile cloud servers. In this paper, we design a system that enables vehicles in a VANET to search for mobile cloud servers and discover their services and resources. Roadside units...
We consider a dynamic vehicle routing problem in wireless networks where messages arriving randomly in time and space are collected by a mobile receiver (vehicle or a collector). The collector is responsible for receiving these messages via wireless communication by dynamically adjusting its position in the network. Our goal is to utilize a combination of wireless transmission and controlled mobility...
