To deal with the challenges posed by device capacity and capability, and also the nature of ad hoc networks, service discovery model is needed that can resolve security and privacy issues with simple solutions. The use of complex algorithms and powerful fixed infrastructure is infeasible due to the volatile nature of mobile ad hoc environment and mobile devices. This paper presents a Secure and Lightweight...
This paper presents an evaluation of in-network caching strategies for efficient delivery of content to mobile devices that are intermittently connected to the network. Placement of content into in-network caches is formulated as an optimization problem that minimizes access latency under certain cost constraints. Several heuristic solutions (longest lifetime, split & longest lifetime and proportional...
This paper describes middleware that establishes a MANET environment with mobile devices and exchanges contents in the devices. The middleware also provides a sharing function as a common service among mobile devices.
In the area of mobile ad hoc and sensor networks, simulation became the evaluation method of choice. Due to the high number of variables - including transmission range, number of nodes, simulation area, mobility pattern-simulation settings vary largely from work to work, depending on the application scenario focused. The results for two simulations with identical setting, but different mobility models,...
In this paper we introduce a novel scenario for environmental sensing based on the combination of simple and cheap RFID-based sensors and mobile devices like mobile phones with integrated RFID readers. We envision a system that exploits the availability of these devices to cooperatively read sensors installed in the environment, and transmit the data to a server infrastructure. To achieve quality...
Three data communication methods can be provided in a MANET: data broadcast, data query, and peer-to-peer messaging. The formation of heterogeneous distributed mobile databases within a MANET that allows people to submit queries or transactions is becoming a reality. Previously, the DD3M data communication protocol (distributed database with 3 communication modes) has been proposed for providing all...
In this paper an instantaneous, high performance, large-scale video surveillance system is presented. Available and future network technologies are analyzed for the dynamical and flexible use of mobile devices in video surveillance. Based on this analysis, video quality levels are proposed followed by wireless ad hoc video surveillance performance levels (WAD levels). Then the systems' structure as...
New social networks are born each day, at a formal conference, at informal social gathering, at family reunions etc. Internet has already been playing an important role in modern way of socialising. But it is still not the optimal way of interaction as one has to be very active updating profiles. With the easy access to mobile devices, modern technologies have now started to adopt to new ways of socialising...
Advancement in mobile devices makes possible to add more features to them while reducing the size. If we also consider the fact that they posses advance communications features, we can convert these devices into the central manager of userspsila activities. One feature in this line is the ability to control the devices surrounding the user. Problems arise when the devices belong to a shared space...
