In this paper, we propose a data forwarding method for efficient data gathering in wireless sensor networks with multiple mobile sinks which freely move in the target region. In our proposed method, each sensor node forwards data packets based on information on connectivity (the status of connection with mobile sinks). As the way to share information on connectivity among neighboring nodes, we integrate...
Newer models for interacting with wireless sensors such as Internet of Things and Sensor Cloud aim to overcome restricted resources and efficiency. The Missouri S&T (science and technology) sensor cloud enables different networks, spread in a huge geographical area, to connect together and be employed simultaneously by multiple users on demand. Virtual sensors, which are at the core of this...
In recent days the advancement in the wireless communication is with that of wireless sensor networks. In Wireless Sensor Networks (WSNs) the data are collected from many sensor nodes by the base station which is the goal of the network. In this type of WSNs, the major constraints are low energy, limited bandwidth and less memory. With these constraints in mind we propose a method to reduce the energy...
This paper proposes a mobile sensing platform that provides context-aware services for mobile users by accessing surrounding wireless sensor networks. The platform provides the following facilities: 1) communicating to wireless sensor networks via a mobile sensor router attached to a userpsilas mobile phone, 2) analyzing the sensed data derived from networks by cooperating with sensor middleware on...
The seamless combining with context-aware sensors and numerous devices and e-home server will soon become a part of our home environment in the near future. We name it as a context-aware home based on ubiquitous computing concept. This context-aware home reduces participations of users in order to realize a ubiquitous computing and automates various services. Therefore, the risk of privacy violation...
In-Motes Bins is an agent based real time In-Motes application developed for sensing light and temperature variations in an environment. In-Motes is a mobile agent middleware that facilitates the rapid deployment of adaptive applications in wireless sensor networks (WSNpsilas). In-Motes Bins is based on the injection of mobile agents into the WSN that can migrate or clone following specific rules...
A principal factor in sensor network design is energy efficiency. In this work, we propose to extend the lifetime of sensor networks using appropriate choice of sensor node distribution. The key idea of our scheme is to deploy more nodes in areas of extensive energy usage. Using this scheme of sensor node distribution, we use probabilistic angular routing to route data packets from the sensor nodes...
This paper presents a distributed fermat-point range estimation strategy, which is important in the moving sensor localization applications. The fermat-point is defined as a point which minimizes the sum of distances from three sensors inside a triangle. This point is indeed at the trianglepsilas center of gravity. We solve the problems of large errors and poor performance in the bounding box algorithm...
Sink mobility has become an increasingly important requirement of various sensor network applications. Handling such mobile sink conditions brings new challenges to large-scale sensor networking. This investigation proposed a hybrid-structure routing protocol (HSRP) that combines the benefits of grid-based and cluster-based structures. Grid-based structure is designed to solve the cluster head selection...
